Knox may also be able to convert fear to enhanced speed.	There appears to be some sort visual change in speed when he attacks the German and Peter.	- It seems unlikely that his ability would also have the effect of granting him enhanced speed such as the ability Daphne has. At the most it would probably only grant him some form of enhanced reflexes. Though it was more likely just a visual effect to show the level of strength he was granted from being near so many frightened people.
Knox's ability also allows him improved reflexes.	None.	+ He is able to reach up and break the neck of Daphne's illusion despite her running at super speeds. (Eris Quod Sum) - Matt presumably wanted Knox to believe that both he and Daphne were dead, so his success at "killing" the Daphne illusion is not necessarily an indication of what would really happen.
Knox's ability involves a limited form of telepathy.	None.	+ There are no significant physical changes in the human body when a person is scared. Knox's ability to detect fear must be limited to the mind and not the body. - On the contrary, there are numerous physical changes in the human body when a person is scared. A change in heartbeat and breathing pattern, sweating, eye movement changes. There are lots of things he could be basing it off. It seems clear he smells fear. + These factors don't hold true for everyone. + Matt and Maury can hear thoughts, yet those sounds aren't actually real. The "smell" of fear could just be manufactured by Knox's brain. - He seems to smell fear, like a dog can. + Perhaps his ability to smell fear is a result of his fear-detecting telepathy, which would probably be located in the olfactory part of his brain, causing him to smell things that are intangible and don't actually give off any odors. • Animals such as dogs and horses do have an olfactory sense developed to the point the can smell fear, the human body releases chemicals that these animals can detect. - This would be closer to empathy (sensing emotions) than telepathy (detecting thoughts).
Knox suffers from intense nasal congestion.	None.	+ Knox deeply inhales through his nose, trying to smell things, but he can't. This might give him enhanced strength. - His power might be augmented by the aroma of waffles. + Villains do not like waffles.
Knox's ability is weaker than Niki's strength.	None.	+ In a one on one fight between them, Niki would have her strength completely and Knox would only have it if she was afraid of him. + Knox isn't that scary. - The more people there are the more stronger he would be. - It could depend on the situation. Niki has proven to be a somewhat timid individual, so Knox would probably make her scared. + Niki was no longer timid after defeating Candace Wilmer. • If Niki were in trouble, not-so-timid-Jessica would take over and snap Knox like a twig. • Niki is likely not timid. In How to Stop an Exploding Man, Niki was brave enough to help Peter against Sylar. • Knox has demonstrated incredible strength with only one scared person near him at the time.
Knox is going to be a heroe.	None.	+ The only reason Knox is a killer is because he was raised in a murderous Los Angeles gang, he will probably become good at some point.
