She was a famous mercenary in the hidden world of evolved human. After the death of Daniel Linderman, she becomes the chairperson of Linderman Group. She is the wife of Aaron Houston and girlfriend of Carlos Mendez, and mother of Kelly Houston and Isaac Mendez. She is an evolved human with the ability to duplicate object and ability.
In the Company
When she was a senior agent of the Company, she joined the war with Dark Knight. She had duplicated Richard Drucker's power and killed him because of his betrayal to the Company. Also, She had written a self-defense system for the Company's satellite.
In 1979, Millie was assigned to capture Mindy Sprague with Agent Haram, Agent Norris and Elle Gracia, Bob's wife. They found that Mindy was hiding in a cabin in Nevada desert. Millie disliked Bob and his plan of conducting research on Mindy and her son, so she tried to rescue Mindy from this.
First, she got help from Victoria Pratt, who provided her some Shanti Virus. By using the virus, Elle became powerless. Then, she persuaded Haram to help her because Haram sympathized with Mindy's situation. But Norris was passionate of catching Mindy, which made him difficult to be handled, since he thought that all evolved humans are potenial dangers to the world, and they should be tied up and locked down forever.
Millie couldn't figure out ways to deal with Norris, but, fortunately, Charles Deveaux was sent to replace Elle. Charles knew their plan of releasing Mindy, and he agreed that, because he thought that the Company should help evolved humans. In the raid on the cabin, Millie tied up Norris with Water manipulation|water-made rope on his bed and flew Spragues to LA. After they released Mindy, Norris escaped and intended to shoot Millie. Before he could pull the trigger, he was brainwashed by Charles Deveaux. Later, they reported that "Mindy Sprague had escaped from her cabin long time ago. There was no clue could find her whereabouts unless using special powers."
As a mercenary
Millie is sitting in a restaurant, reading a book, when Angela walks in. She makes a comment about Angela being late and then looks up from her book to look at Angela. When she does so, Millie tells Angela that she looks like she has been mugged and her dignity was the first thing to be taken. Angela responds by saying that she has been having a bad day. To this Millie response by telling Angela that she was detained by men with badges, and that they were questioning her about the company that she might or might not have kept. Angela tells Millie that she is in trouble, to which Millie response by saying that she (and others) knew that she has not been the same since Arthur has died. Millie continues by asking, "What did you do?" In response, Angela tells Millie that she is just trying to get her sons out of the trouble that she placed them in. Angela goes on to tell Millie that she needs some clothes, a car and whatever cash Millie has so that she can disappear. Millie tells Angela that she should give herself over to the authorities and just stop running. Angela tells Millie that she is sorry to have bothered her and that it was good to see her; she then gets up to leave. Millie tells Angela to wait and gives her a couple hundred dollars. Angela tells Millie to enjoy her lunch, steals Millie's umbrella and then leaves.
"Nathan" comes to see Millie and asks if she knows anything about the disappearance of her daughter, Kelly Houston. Millie admits she thought Nathan may have been involved and hired a private investigator, who confirmed that Millie bought tickets to London and picked up her luggage using a claim ticket at Heathrow. Millie admits she was an inattentive mother and Kelly grew up to be a spiteful child as a result. She invites "Nathan" to find his own way out.
Later, "Nathan" returns and tells her that he has remembered that he was involved in Kelly's accidental death in the pool. Millie seemingly believes that he's playing some sick game and tells him to go away.
Subsequently, Millie meets Angela for dinner. She tells Angela what "Nathan" told her and Angela apologizes for her son, saying he hasn't been himself recently. Millie receives a call from her hired assassin, who has abducted who they believe to be Nathan, taken him out into the woods, and killed and buried him. Millie offers a toast for "closure". After the meal with Angela, she waits for the assassin, and murders him by using metallized bone spike.
