Theory	Citations	Notes
Peter will gain his scar and then reacquire regeneration, but the scar will not go away.	None.	+ It seems Peter cannot scar when he has Claire's ability, but Peter no longer has that ability. + Both versions of future Peter had a scar. - Future Peter did not seem to know Arthur was alive and could still retain multiple abilities; he likely never had his abilites stolen by Arthur. • It is possible that exposed future Peter lost his powers to his father and somehow regained them. He knows the only way to stop Arthur, and the Earth from exploding, is to give him access to Sylar's power. + Peter's ability only allows him to hold one power at a time now, so he may be scarred when not holding Claire's ability. - Claire's ability can cure damage done before the ability is activated. Her ability herself when the eclipse was gone and the ability back. + If Peter gets a wound that originates the scar and it heals before he gets Claire's ability, the ability won't heal it, since scar tissue from a healed injury isn't an injured tissue. - In 1961, Linderman heals an old scar on the back of Angela's leg, though it is unsure if his healing ability works similarly to Claire's regeneration. + It has been shown in Turn and Face the Strange by Sylar that Claire's regeneration can be suppressed. + If the wound was cauterized, it might not be able to heal correctly.
Peter will always "aid" or inconsequentially be the villain.	"The only future I've ever seen is the one caused by you." - Angela to Future Peter in The Second Coming	+ Peter was the bomb in Season One. + Peter almost released the virus in Season Two. • Angela claims that Peter is the cause of all of her futuristic dreams which has a certain implication of dark futures. - Peter was shown dead in Angela's dream of villains in Level 5. + Future Peter causes a Butterfly Effect which leads to Angela's newest foreshadowing of destruction and chaos. + It was because Peter told Claire to stay at home that Sylar obtained her power. Even Angela stated she "wasn't where she was supposed to be." (The Second Coming) - In the original exposed timeline, Nathan was the cause of the events of that timeline (e.g. evolved humans in camps, experimentation and being hunted down). + Peter has a ability-control percentile of 27% (Assignment Tracker 2.0, under Gabriel Gray's profile), thus sort of making him predisposed to blundering and losing control.
Peter cannot obtain the the Haitian's power because the Haitian would block Peter's innate ability before Peter could use it.	None.	+ Peter has not displayed the Haitian's ability. - It is just as likely the act of having the Haitian remove his memories allowed Peter to absorb the Haitian's abilities - memory/mind manipulation on self as well as others. - Peter was able to use telekinesis and/or space/time manipulation to stop taser darts shot by Noah Bennet and the Haitian from hitting him despite the fact that the Haitian was close enough to block him from using his abilities, this seems to indicate that Peter was automatically blocking the Haitian from blocking him (Peter at that time didn't know about the Haitian's ability). + The Haitian was able to erase Peter's mind and stop him from using an ability in Four Months Ago. Having the Haitian's ability might make Peter immune to this. - The Haitian's ability is inactive if he is dead or unconscious, so Peter could absorb his power, if he could knock him unconscious. - In Resistance, Future Peter says he won't make Claire forget "again". At this point, he apparently has already absorbed and learned to use the Haitian's memory-erasing abilities, if not the power-suppressing ones. - It is likely that the Haitian's power to block abilities requires his conscious effort to exercise. It would explain why Peter was able to block said darts, as well as the reason why, in One of Us, One of Them, Daphne was able to flee the theatre while Hiro's ability was blocked. + Guillame, Daphne and Hiro were blocked without the Haitian specifically trying to block them specifically. - The Haitian was on an assignment; it would be logical for him to automatically block any ability he might come across, so as long as it's within his reach, every ability would be blocked, even if he didn't know who had an ability and which. • When blocking Arthur's abilities the Haitian is straining to keep them in check, though this may only be because Arthur is too strong for him to passively block the abilities. - It is possible that the Haitian, as with other heroes with passive abilities, can suppress his power dampening if he wants to.
Peter absorbed the power of persuasion from Eden McCain.	When Peter visited Mohinder Suresh's apartment, Eden McCain was present. They were in the same room for some time, even coming in physical contact with each other. (Collision)	+ Eden could use her power at her discretion; it's possible Peter duplicated it and simply didn't know how to activate it. + Additionally, the fact that Peter was able to convince Mohinder to visit Isaac, but later fail to do it again may suggest that Peter tapped into Eden's power, but later did not. + He doesn't need to know that someone has a power to absorb it; but still needs some knowledge of what the power is if it is a active power. + He absorbed Bob and Elle Bishop's abilities, Elle used hers on Peter, so he knew what she could do; however he doesn't know Bob can do. + He used D.L. Hawkins phase shifting ability to escape with Adam Monroe, even though Peter hasn't meet him before "How to Stop and Exploding Man". It seems that once he knows how to tap into an ability, he can do it again. - They could've met before in an unaired encounter and he saw him use his phase shifting ability. + Peter seemed immune to Parkman's suggestions in Powerless. - He had telepathy, the same ability that was being used against him. • Maury and Matt have trapped each other in illusions made by telepathy. Telepathic illusions aren't an example of ability immunity. • Peter has nowhere near as much experience with the ability as Maury had.
In the original timeline (Nov 8, 2007), Peter Petrelli mimicked density manipulation from one of the Moab prison ambush agents.	Graphic Novel snapshot:	+ In Walls, Part 2, everyone is accounted for except for Peter and the agent with enhanced speed. + The agent looks to be stepping backwards (not running), and the silhouette for Peter resembles the image of the larger ambush agent. + If Peter was using enhanced speed, the artist would have drawn jet-trails to indicate this. - There is little evidence of anything from the shadows of the image. That being said, it is clear that the female agent with super speed is running towards the source of light while Peter is running perpendicular to the source of light. Furthermore, people rarely draw jet-trails on shadows. Instead, the shape and size of the shadows are exaggerated to give the illusion of being "in two places at once".
Peter Petrelli's name is a reference to the many Marvel characters having first and last names that begin with the same letter.	None.	+ Many of the Marvel comics characters have names beginning with the same letter (e.g. Peter Parker, Reed Richards, Sue Storm, Matt Murdock, Scott Summers, Warren Worthington, Bruce Banner, Stephen Strange). • Many characters in DC Comics also have this naming convention, with most characters having initials L.L., not to mention characters like Guy Gardner (the Green Lantern) and J'onn J'onzz (Martian Manhunter). + The show's writers have referenced popular culture with other character names: Claude Rains is a reference to the original actor to play a character who was invisible. - Tim Kring does not read comics. • Yet many Comics have entered many other forms of media including film, T.V, games, etc. Why a few characters have a "superstar" fame such as Spider-man or Batman, is unlikely that Kring has not come across a comic character in any media form. - It's not just Marvel that uses this style of name; in fact, the first to do so was Detective Comics, with Clark Kent, Lex Luthor, Lois Lane, Lana Lang, etc. Alliterative names are very common because they are easy to remember and sound nice.
Peter absorbed the power to heal from Linderman at some point in the past.	This could be how Nathan was healed from the brink of death.	- Peter has never shown that he can use Linderman's power. + It may simply be dormant, if Peter is either unaware Linderman had a power or is somehow unable to empathize with Linderman, and, thus, cannot use his power. + Future Peter may have used this ability to heal Nathan in The Second Coming. - Future Peter had four years to absorb this ability elsewhere. - Nathan believes God directly healed him, and the writers say they are sticking with that explanation. + Since it seems to have taken Linderman years to perfect his power, Peter might not be skilled enough to use it, and if he can, not very well. - Peter has absorbed abilities from others who haven't been able to control it well and he uses it fine. + He could have absorbed it at Arthur and Angela's 41st anniversary party in Villains. - Peter's absorption may not have manifested yet at this point. Peter's earliest known power use was in April 2006, when he used his mother's ability to see Heidi and Nathan's accident. + He could have had the ability for years, only not known he had it until he healed Nathan. As far as we know, he didn't know Linderman had the ability, so he wouldn't have realized he absorbed it.
Peter could have been able to use Charlie's enhanced memory through his contact with Sylar.	None.	+ His mother told him to remember, and shortly after he appeared to remember all the moments that he spent with his mother in his entire life. (Out of Time) - Adam helped Peter remember who he was and how they got to Montreal by simply explaining his brain cells needed to heal. The instance in the future seems more along the lines of the same principle.
Someone wanted Peter to come into contact with Ricky's gang.	Ricky commented on the unlikeliness of Peter showing up in the one container that they were set to rob. (Lizards)	+ Ricky and his gang specifically planned to break into one container out of the hundreds in the storage lot. It would be a ridiculous coincidence if Peter just happened to be in that container. + Peter's container was empty, but, according to Ricky, it was supposed to be filled with iPods. + Peter is often considered to be the most powerful hero, due to his ability to absorb the powers of others. It is therefore likely that someone hopes to manipulate him into helping them. + The Company was able to trace Peter to Ireland, without Molly or radioactive isotopes. - Why would Ricky try to hide Peter from Elle if they were on the same side? - Why would Elle kill Ricky if they were on the same side? + Ricky and his gang are not necessarily the ones manipulated the situation. The Haitian or some other character may have wanted Peter to interact with Ricky's gang for reasons of his own, possibly something to do with Caitlin. - The Haitian trapped Peter in a random container, it was just pure luck. • If Arthur Petrelli does have the ability of luck manipulation, this could just explain the pure luck. - Elle was looking for containers at the dock first. If she knew Ricky and his gang had him, she would have gone there first. • This is assuming that the Haitian was working with the company.
Peter exhibited a new use of his dream power by bringing back the evacuation notice in Truth and Consequences.	None.	+ Peter has used this dream power before in connection with Charles Deveaux (see Theory:Charles Deveaux), however this time he brought back a physical object from that place/time. Thus, he is not just a astral projection, but can physically interact with that location. + This can not be an example of space-time manipulation because Adam does not see him "leave" his present location in the building in Montreal. In a sense, he is in two places at once. - Peter could have simply returned to the exact time he left. + Adam claims to have heard Peter screaming Caitlin's name while Peter was gone - this could not have happened if time was frozen because he would have been gone and back in an instant. • Peter continued to yell her name when he was with Adam in the present. • Adam heard Peter, but neither Caitlin nor the version of Peter with her seemed to hear Peter, which may indicate some sort of transcendent or dream-like state because he was apparently audible and physically present for Adam, but he obtained a flyer from the future and brought it back to the past with him.
The Haitian, by removing Peter's memories, has irreversibly enabled Peter to access multiple powers at a single time.	In many episodes (Kindred, Truth and Consequences, Powerless, etc.), Peter has used multiple abilities at once.	- This could have initially been an ability to use all passive abilities (or a constant use of all passive abilities), because rapid cell regeneration, immunity to space-time freezing, and immunity to telepathic suggestion do not necessarily require the intent to use an ability. + Peter was able to actively simultaneously implant a thought into Matt's head and telekinetically throw Matt backwards in Powerless. • Peter was not able to recover his memory until Adam told him to use his ability. • This may have been a use of the Haitian's ability, reversing damage, but it also could have been Adam's rapid cell regeneration.
Peter absorbed Candice's illusion ability, Micah's technopathy and Molly's clairvoyance.	He was quite close to them both during the final scene of "How To Stop An Exploding Man".	+ Peter absorbed phasing from D.L. by only being in the same general area. D.L. was sitting with Micah and Molly at the time. + Candice dragged Sylar away. - Candice only dragged Sylar after Nathan flew with Peter, so she was probably out of his mimicking range. + Future Peter was able to cast illusions (The Second Coming). Maybe he learned to access Candice's ability like he learned to access Sylar's intuitive aptitude.
Peter will go insane.	None.	+ It has been suggested that the numerous alterations to Sylar's DNA has unbalanced his mind. The same might happen to Peter. + He's already started to feel the "hunger" that comes with Sylar's power, even killing Nathan in a potential future. - It has been said that the Hunger is a part of Sylar's power, so it only makes sense that Peter would gain this alongside the intuitive aptitude.
Peter has absorbed the powers of people that were walking down the street, at stores and other public places near him.	None.	- This would be a poor explanation by the writers, as many potentially exciting plot twists will no longer be able to occur. + It might not give the show the same story line development, but the person he walks by could be a character we will meet later, like Harry Fletcher or Sparrow Redhouse; perhaps even someone we have seen but Peter has not met. • Peter has said that he has to remember how the person made him feel to use their power. Most likely, he won't remember how someone made him feel if he only walked by them. • There have been occasions where Peter was able to use his ability without prolonged interaction with the person, such as with DL and Claude.
Peter, and Nathan Petrelli are brothers with Hiro Nakamura.	Hiro's biological mother may actually be Angela Petrelli, since we know she slept with Kaito Nakamura. (Lizards)
The ability Future Peter used to transform is illusion from Candice Wilmer.	None.	+ The effects used are exactly the same. - Future Peter may have acquired the power from another person.
Peter will have to kill himself in the past to stop the exposed future from happening.	None.	Future Peter references stepping on too many butterflies. In The Butterfly Effect (movie) (directors cut), the main character Evan Treborn (Ashton Kutcher) realizes that the only way to save everyone is to eliminate himself and goes back to his birth and kills himself. - The phrase "Butterfly Effect" predates the film, and the writers stealing the film's plot is unlikely. - That might cause a paradox. + Paradoxes have never been shown to exist in Heroes. - The formula, the main problem with the exposed future, has already been destroyed.
Peter is able to use Sylar's telekinesis and intuitive aptitude because he sees Sylar and Gabriel Gray as two separate persons.	Peter did not know of or use intuitive aptitude until he met Sylar in the exposed future.	+ The first (and only) power Peter mimicked from Sylar had been telekinesis (Unexpected), until Gabriel Gray taught him how to use intuitive aptitude. He may forever associate telekinesis with Sylar and intuitive aptitude with Gabriel Gray. - Peter never knew of intuitive aptitude, and therefore never tried to use it, until I Am Become Death.
Peter still has intuitive aptitude.	None.	+ The Company was unable to detect it in Sylar (Godsend), so the ability may be undetectable to Arthur as well. - Arthur may not have to detect all of Peter's copied abilities to absorb them. • Arthur stole Peter's base ability of empathic mimicry, which he presumably needs to run the rest of his abilities.
Peter has kept his mother's precognitive dreaming ability.	Peter had visions after losing his powers.	+ This is the first power Peter copied, which may have made it his "natural power" or simply made it have a stronger link to him. + The first power Sylar stole was telekinesis and this was the only ability The Company was able to detect in him, despite having others. - Sylar retained his telekinesis because of latent guilt over killing Brian Davis; Peter does not feel guilty about taking his mother's ability. + Despite the Shanti virus, Sylar was able to regain telekinesis, as well as his natural ability. - Sylar did not regain telekinesis until his other ability was restored. - This is because Sylar absorbed telekinesis through empathy; the abilities Peter lost were gained through empathic mimicry. - The visions were flashbacks to help further the plot.
Peter automatically 'connects' with everyone he meets.	None.	+ Peter is able to use the powers of anyone he meets, regardless of how long he knows them. + His parents may have treated him the way they did in order to make him ultra-sensitive so that he'd absorb powers easily. • In a Behind the Eclipse interview, Joe Pokaski and Aron Coleite stated that "Peter has learned and will continue to learn that's it's more about his heart than his memory". + Peter has an empathic personality; Charles says Peter can love unconditionally.
When Future Peter brought his present self to 2011, he lost his powers at once.	None.	+ By bringing his present self along, Future Peter forced him to acquire intuitive aptitude. Thus present-day Peter became aggressive and impatient, he went to Pinehearst and lost his powers. This could have affected Future Peter as well, so when they time traveled to 2011, he rendered himself powerless. - By traveling to the explosion future, Hiro became determined to stop it, and succeeded. By the same logic, Future Hiro should have been affected as well, forgetting that he was from the explosion future. + Future Peter did not heal from the bullet to his chest. - The Haitian was suppressing his ability. That's what allowed Claire to kill him. She even said, "Trying to teleport? That won't work with my friend here." + Future Peter wasn't shot in his head. And he was shown laying on a table dead without the Haitian present. Obviously he didn't have regeneration. - Future Peter was physically close to Future Claire in the first scene of Volume Three, if he didn't have regeneration until then he had it after that moment. • This could be because Peter needs his empathic mimicry in order to use his acquired abilities, and if the Haitian suppresses it and he dies, he can no longer tap into it. If he dies and his mimicry is working, then he can come back to life due to his passive powers being constantly active. + Peter was able to come back to life when Claire removed the shard of glass from his head. Dead evolved humans cannot access their abilities, so the Haitian had nothing to block.
Peter's empathic mimicry is still the same, it appears to work differently because he no longer connects to people like he used to.	He didn't want to get involved when Claire was on the phone and now he can only mimic an ability through touch.	+ Being betrayed by your brother after having to kill the father who is a manipulative villain could very well make Peter less willing to connect with people. + Hiro's ability weakened when he lost confidence in himself, proving abilities can be affected by ones state of mind. + Arthur said that he would regain his abilities. - Arthur said something like "You'll regain your abilities", yours refering to Peter's abilities. - If Peter's DNA changes like Sylar's when he gains a new ability, then the changes in Peter's DNA could have affected his original ability. + Peter had already mimicked several abilities, none of which affected his original ability. + Peter's ability is changing his DNA to incorporate new abilities, not altering the DNA responsible for his original ability. + Peter mentions in the first episode of Volume 4 that he isn't strong enough, which indicates that if he were stronger he could have kept all of his powers at one time, and saved that person. + Peter doesn't quite know why his ability works the way it does now. If it were an altogether different ability, he should have realized it.
Peter has consciously or subconsciously limited the scope of his ability to prevent himself from acquiring new abilities, ensuring he has a better control over the abilities he chooses to acquire.	Peter made a choice to get Mohinder's ability.	+ The events on the airplane can lead to this theory. - Peter told Tracy about the limitation of his new ability (one power for another). + If the effect is due to a subconscious decision, Peter might not be aware of that, he might be limiting his ability without knowing. + Hiro's ability was similarly affected when he lost his confidence when he could not save Charlie from Sylar. With his trust broken by Nathan, Peter would not be able to hold more than one ability until he regains his confidence and makes amends with his brother.
Peter's original ability was sympathetic mimicry and Sylar's is empathic.	Each have their own method of gaining abilities.	+ Tim Kring described Peter and Sylar as "two halves of a similar coin." + Arthur Petrelli described Sylar's ability as "accessing his empathy". Empathy usually applies when you share a trait with someone. + Peter never had to touch people to gain their abilities. He simply could absorb them. Sympathizing does not require you to share a trait with other people. - Sylar's Assignment tracker page specifically lists his ability as Intuitive aptitude. - What Kring may have referred to was Peter's heart, Sylar's lack of one, and their shared ability of copying/taking abilities.
If Peter meets Arthur again (if he is alive or using some form of time travel) Peter could use his current ability to copy the power-stealing power and steal back all of his powers.	None.	• He could also have his current mimicry stolen first.
Aside from the fact Peter has to touch a person to get their powers, Peter's new power works the same as his original power.	None.	+ He could only use one power at a time until Claude taught him how to access multiple powers at the same time, and out of the absorbee presence. - This is probably only because multiple evolved humans were rarely in Peter's presence at the same time, back then.
If Peter travels back in time and uses his current ability on his past self he can gain back his empathic mimicry.	None.	• This would only be possible if Hiro gains back his Space-time manipulation ability back or Peter meets another time traveler. • Should Peter absorb empathic mimicry, he'd lose it again if he used ability replication on another evolved human. + Not if he doesn't use ability replication, he could learn to rely only on his original ability. • Time travel is currently impossible.
If Peter has Ando supercharge his ability, he will be able to retain multiple abilities at once.	None.	+ Supercharging enhances abilities, so it only makes sense that if you supercharge ability replication, you would end up with at least the ability to hold multiple powers at once. • So far, the Ando's enhancements of others abilities are temporary. + However, if Ando charged Peter every time he touched someone, Peter could theoretically hold that power in addition to the ones he already has.
When Arthur stole Peter's ability he removed the ability genes from his DNA. And when he used the formula, it gave him new ability genes which gave him his current ability.	None.	- Alternatively, he could have turned the DNA responsible for Peter's ability in non-coding DNA, a.k.a. junk DNA. - The formula doesn't "give" genes, it "unlocks" those which are inactive in DNA of every non-powered human. Otherwise it would be impossible to give abilities to people. + Peter and Sylar alter their DNA, which results in acquiring new abilities. - Mohinder said that a synthetic ability depends upon an individuum's unique DNA chemistry. Peter shouldn't have acquired an ability different from the old one. + But Peter's DNA was changed - Arthur must have removed the ability genes from it and insert in his own. Sylar himself refused to kill Peter because the latter had no powers, he couldn't even find them in Peter's brain. • Sylar didn't even look for powers in Peter, he knew Peter had been depowered.
Peter's weakened ability represents his disgust towards himself for acquiring it, as well as his brothers betrayal.	None.	+ Peter has a very fragile psyche, and it tends to manifest itself in his powers. He wanted to become a hero without them, yet still had to inject himself with a serum he was trying to destroy to save a brother who only rejected him. This could cause him to lose his empathy, hence the necessity of contact for his new ability to work, as well as make him lose confidence in himself, explaining why it's been weakened. As the writers have said before, it's more about what's in his heart.
Peter will come into contact with Sylar and replicate all of Sylar's abilities one by one, at some point gaining Sylar's intuitive aptitude, then use it to empathically gain other evolved humans' powers in a manner similar to his empathic mimicry.	None.	- Remembering the experience of absorbing intuitive aptitude, Peter might never attempt to acquire it again. + Since Peter doesn't know that Nathan is Sylar, he might accidentally obtain it by coming into contact with him.
Peter's ability is simply in it's early stages, similar to how Peter had to learn to use empathic mimicry.	None.	+ Peter had to learn how to recall abilities, this took a great deal of time. + Peter's ability is still the copying of others, assuming his "blood chemistry" hasn't changed his ability should have similar traits to his original. + Abilities evolve over time, telepathy, induced radioactivity, electric manipulation and others have all been shown to increase in power, and have the user develop a higher control over it as time progresses. + As stated earlier, Peter's psyche is somewhat scarred from his brother's betrayal of the evolved humans, and, as such, he may have empathic mimicry but may not be able to totally access it because of this mental strife. Hiro went through a similar weakening of his powers in season one, but recovered them after dealing with his inner turmoil by receiving his father's blessing.
Peter Petrelli's original power was ability replication, and he replicated Sylar's empathic mimicry in "Homecoming".	Peter touched Sylar before becoming proficient with abilities. (Homecoming)	- Sylar's ability has been explicitly shown to be intuitive aptitude in his assignment tracker profile. + Sylar could have mimicked intuitive aptitude from Samson Gray. - Sylar might have been too young for his ability to manifest in order to copy his father's. + There is no explicit proof that the assignment tracker profiles are 100% correct. As far as we know, they are merely what the Company knows about the person. - Peter hadn't met Sylar when he first flew because of Nathan. + Peter could have used ability replication by touching evolved humans, before coming into contact with Sylar. - Peter's ability has been explicitly shown to be empathic mimicry in the assignment tracker map. + As stated above, there is no explicit proof that the assignment trackers are 100% correct. - In Villains, Angela tells Arthur that Peter will become a very powerful man when his ability manifests. Ability replication can hardly lead to gaining a great power, since it allows to hold only one ability at a time. + It's possible Peter's ability will evolve, and he will be able to replicate multiple abilities. • Then it would only differ from empathic mimicry through the physical contact. + Angela could have foreseen that Peter's would ultimately end up with empathic mimicry. - Peter apparently didn't touch Future Hiro, but successfully mimicked his power. • The Hiro Nakamura from the explosion future demonstrated an immense control over his ability, it is not hard to believe that he controlled the temporal state of Peter as well. - Peter was shown to be immune to time-freezing after mimicking that ability, present day Hiro was unable to freeze him when Peter was helping Adam. Peter was the one responsible for his not freezing in time, not future Hiro. • Such a thing was never observed anywhere else. - Peter managed to stop time with Claude, when he had not met any known time stoppers since meeting Sylar. (Unexpected)
The Future Peter from the exposed future had ability replication, not empathic mimicry.	Future Peter did not regenerate, while the Haitian did not stop present-day Peter from killing Nathan. (I Am Become Death)	- The future Peter has displayed more than one ability at a time on numerous occasions. + The future Peter could have learned to attain more than one ability at a time. - The future had not been changed yet, so that Peter probably never lost his ability, or injected himself with the formula, getting a new ability. + Future Peter had a scar, which seems to imply that he had lost his ability to regenerate at some point. • See the theory page about Peter's scar for more on this.
Peter would regain his original ability if he came in contact with Matt Parkman, Jr..	Matt Jr.'s power was able to jumpstart Hiro's ability, even after it was stolen by Arthur.	- Matt Parkman, Jr. gave Hiro a weakened version of his previous ability. The formula gave Peter a weakened version of his previous ability. There is no reason to think that he would get a different ability with Matt Parkman Jr. than with the formula. + Hiro was completely depowered when Matt Jr. jumpstarted him, Peter already has something, Matt Jr.'s ability could "finish the work" the formula started. + Since Hiro's ability was removed by Arthur Petrelli and yet he was able to regain his ability from Matt Jr.'s ability (however it is not been clear as to whether Hiro has gained control of his ability without being in contact with Matt Jr.) then the same may be true for Peter being able to regain his ability by touching Matt Jr. + Matt Jr.'s power can develop and get stronger. - IT has been stated by the writers that Peter's current ability is not a weakened version of his old one but a new ability altogether.
If Peter engaged in a group hug with other evolved humans, he could retain multiple powers at once.	None.	+ He has demonstrated the ability to hold a power upon physical contact. - Peter loses his retained ability when he replicates a new one. + He might be able to retain multiple abilities if he replicates them at the same time. - Peter could only replicate one power from Sylar in An Invisible Thread, and he chose to replicate shape shifting. • Sylar is not multiple people. - It hasn't been confirmed that Peter only absorbed one ability from Sylar, or the whole package. + Obviously, he did not absorb the whole package or else he would have healed from his injuries after he fought with Sylar. • Matt Parkman may have suppressed Sylar, so now he only has: intuitive aptitude, telekinesis, electric manipulation and shape shifting. Because they were mimicked empathically, while intuitive abilites are lost.
Peter has, in fact, acquired all of Sylar's abilities.	None.	+ In Four Months Later... when Peter healed from the beating he had received, he didn't appear to be healed until after Caitlin wiped the blood off of his face. This could be the same reason it didn't seem like Peter had healed after absorbing Sylar's powers: the blood from the battle was still there. - Peter has healed with blood before. + Nathan told a government security official that Peter could do what Sylar can do. - Nathan could be talking about shape shifting. - Claire asked Peter if he could fly, and he said no. • It is unknown if Sylar had flight or was using telekenisis to levitate himself. If he was, Peter might not be able to use TK to fly just yet. + Apparently Peter used Regeneration to heal his injuries from the fight. - No, he didn't, the wounds are still there when James Martin's body is burned. + Peter gained as much control as Sylar had over shape shifting in minutes--while the original bearer of the power (who had it for a much longer time) never gained that much control of it. This suggests that Peter gained some degree of intuitive aptitude. + It seems when Peter replicated other peoples power that he actually gets the same amount of control over the power that the person he replicated it from had. Which would explain how he had such fine control when he replicated shape shifting from Sylar (he was able shift within seconds which is about as fast as Sylar was able to), and when he replicated telepathy from Matt Parkman. - Peter didn't display the Hunger that comes with it, implying he didn't get it. + He didn't come in contact with anyone with an ability he didn't already have. - Peter uses the abilities he absorbs at much higher level without intuitive aptitude. • Peter has had experience with empathy, so he could use the empathy aspect of intuitive aptitude to gain powers, and not suffer from the hunger. + Both were blasted by electricity. Nathan was shown to have at least a little bit of burning, while Peter showed little, if not none.
