Background[]
Eve was created in a government lab as a project to make the ultimate superhero, but under control of the U.S. military. The project was spearheaded by Dr. Elias Brandyworth who utilized a down on their luck woman named Polly in the experiments. However, Polly eventually grew attached to her unborn child and wished to protect her from the government and Elias soon came to feel the same way.
At some point, the building that Elias and Polly resided in came under attack by the Lizard League who dueled with the Guardians of the Globe. This event was in actuality created by Elias to serve as a distraction so he and Polly could escape. The two fled to the Valley Hospital but during the trip, Polly started going into early labor and due to the baby's unique nature, powerful energy was being generated inside Polly which was slowly killing her. During this time, the government leader, Erickson, attempted to make Dr. Brandyworth bring Polly and her soon to be born baby back to the lab. Brandyworth refused and continued taking her to the hospital where the child would be born and swapped with the stillborn baby of Betsy and Adam Wilkins to get her out of the life of being used as a weapon by the U.S. military.

Betsy reads to her daughter.
Samantha Eve Wilkins, as they named her would be raised by them and throughout her early life she would stare at the molecules in the world around her. Her parents thought this behavior was odd however. She would also draw molecules and build them out of LEGOs. She helped her babysitter Zack study for his chemistry test which he presumably did well on. After this, her parents decided to enroll her in a special school for gifted children, though Samantha did not really enjoy it, as she had no real friends there.

Samantha Eve Wilkins, discovers her powers, have turned a book into solid glass!
Samantha eventually made her first real friend in a girl named Val and a few years later, the former would discover her powers. However, when she showed off her powers to Val, it only scared her away which resulted in their friendship ending. Samantha would then get dismissed of her special school and then enroll in a public one.

Samantha Eve Wilkins' first night as a superhero.
Sometime later, Samantha would start her career as a superhero known as Atom Eve, aiming to use her powers to fight crime. However, this would draw the attention of Dr. Elias Brandyworth who went into hiding to avoid the government which sought to use her as a weapon in the first place. He warned her not to use her powers since it would risk revealing her existence to the government, though they eventually did discover that Sam was alive from witnessing her use her powers after she chose not to listen to Elias.
The government immediately sent their creations and failed attempts to replicate Samantha's powers, her siblings, to retrieve her. Samantha fought against them but due to their unstable nature, they all soon perished one-by-one throughout the battle. Distraught and weakened from the fight, Samantha was captured alongside Elias by the government.
Inside their lab, the government intended to use both Samantha and Elias to create more of the former. They then revealed that Polly, Sam's biological mother was still alive, but put in horrific condition all so they could use her to create her unfortunate siblings. Elias fought against the government but was accidentally killed alongside Polly in the ensuing fight. Their two deaths bolstered Sam's powers and enraged her to the point where she would use them to erase the government officials' memories of ever trying to create her. Sam fled the scene and returned home only to find out she had missed her birthday party. She then got into a fight with her father and retreated to her room, still mourning over the loss of all those involved in her birth and was then comforted by her adopted mom.
Sam would continue her superhero career as Atom Eve and soon she became part of group of heroes known as the Teen Team. She would enter a relationship with one her fellow members named Rex Splode.

Teen Team attacks the aliens, who were fighting with superior technology than they were. Eve was able to drive many of them back, but had something thrown to her face which covered it, compromising her concentration and leaving Eve helpless. Mark deflected beams thrown at him by cannons and was taken out by a kind of glue which didn't let him move. Robot tells the team that the Flaxans seemed to have used their time wisely. When the Flaxans' leader was about to kill Eve, Invincible let out a yell which blew everything at a certain radius away from him. He punched the Flaxan leader, who started aging once his bracelet broke and saved Eve.

He's told by Eve that the actual bodies were elsewhere since people looking for souvenirs later. Nolan tells the people gathered that the people who had died were his friends and mentors. He mentions that at least the fallen heroes would rest together and Olga was upset that she couldn't see her late husband. When she threw herself at the ground, Debbie rushed to help her.

Mark asks if Cecil if he had been spying on him, but Cecil tells him that if he wants to be a hero, privacy isn't an option. Mark points out that he didn't even work for him, but Cecil counters by telling him he never would if he never showed respect or decided if he wanted to be a hero. Mark is forced to decide then, and he says he does want to be a hero. Cecil hands him a comm device and tells him Eve would be there as well. Cecil tells him that he needs to go to Mount Rushmore, which Mark doesn't know where to find. His boss complains that schools didn't teach enough and leaves. Amber walks back in and Mark makes up a lame excuse to leave. As Debbie walked in with snacks, Mark smiled nervously and left.

Invincible and Atom Eve fought Doc Seismic, who was threatening Mount Rushmore.
Invincible and Atom Eve flew towards Mount Rushmore. As they did, Cecil told them that he wouldn't be asking for their help, but Omni-Man was busy and the new Guardians were a shitshow. He tells them their target was Doc Seismic, who was doing things which made no sense. They believe that the gloves causes him a concussion every time he uses them.
Doc Seismic causes eruptions, and causes Mount Rushmore to split. As Abraham Lincoln's face fell, Invincible caught it just in time before it hurt anybody, putting it back. Invincible and Eve fight Doc Seismic, who uses his bracelets to escape from them at a high speed, and telling them that they should be on his side.

Eve breaks up with Rex definitively when he tried to apologize.
Eve takes down her pictures with Rex and cries as she does so. When she goes outside, she sees fireworks while smiling. She meets Rex, who made them with his powers. He tells her he knew he had screwed up, but didn't know why since he loved her. He asks for a do-over, but Eve declines and wishes him luck with his new team and leaves.
Eve goes to Mark's house, only to find him on his bed with Amber, kissing her. She tells herself that that was good for Mark and is glad he found someone and then flies away.

Mark and Eve talk about Amber.
Finding her own path[]
At school, Mark tells Eve that he didn't want to lie to Amber but also couldn't tell her the truth. Eve tells him that that was why dating normal people sucked, but Mark counters by saying that things between her and Rex hadn't worked out, which angered her. Mark apologizes to her. She tells him that she had a lot of things to deal with, so he asks her to help him out with Amber stuff and he would help her out with her stuff. However, she mentions that she doesn't know if she wants to be a superhero at the moment, so Mark tells her that he would be there for her if she needed to talk about it. She leaves but turns around to tell him that he should only tell Amber his identity if he was serious about her.
After class, Mark complains about a test, but Eve tells him it's important. When Mark asks if she was okay, she tells him she had left home and didn't know what she was doing. Amber joins them and asks Mark if he would be joining her. Mark tells her he would and Amber tells Eve that Mark had volunteered to help at the Beckwell Community Center, where they cooked dinners for anyone who was hungry, which impressed Mark.
After Mark left, Amber invites Eve, who tried to excuse herself, but couldn't since she was no longer busy saving the world. Before she left, Amber asks Eve if she had seen Mark acting weird since he was always late and didn't show at times. Eve defends Mark, however, telling her that even though Mark was bad at time management, he was a good guy.
Eve meets Amber at Beckwell Community Center, where the latter shows her around. When Eve asks if Mark was there, she's told that he had 15 minutes to be there or he would be dumped. Eve is handed an apron and is put on chopping duty.
Amber and Eve pour soup for everybody, who Amber knows. Eve tells her that being so involved was impressive, but Amber says that she had thought Mark would be there with her.
Later Eve gets a call telling that Mark is injured and tells Amber that she knows it's hard to love someone even when it seems that they don't love you back but assured her that Mark loves her and be there if he could.
When Mark wakes after having nearly died, Nolan tells him he knew he would pull through and tells him he was out for six days, which shocks Mark. Eve tells him he covered for him with Amber, telling her he had gotten hit by a bus and mentions Monster Girl and Black Samson were still unconscious.
In Mark's room, Eve pays him a visit; he thanks her for talking to Amber when he got hurt and hugs her. He tells her he would be visiting Upstate University and invites her, but she mentions that she wouldn't be going to college. Mark questions why since her grades were way better than his. Eve says that when she was with Amber at the community center something with her and that she didn't need to wait for an alien invasion or the Lizard League's next attack. With her powers she could stop natural disasters and make peoples lives better. Mark understands understand, which somewhat surprises Eve, but he tells her that he had messed up downtown and that Black Samson and Monster Girl nearly died because of him and wonders if both of them need a fresh start. Debbie calls Mark, telling him that William and Amber were there and Eve looks at him for moment then leaves.
Eve's mother asks why Eve couldn't do her superhero work from home, but she tells her that she knew why as she made the door disappear on her father. Her father comes from around the back and tells her that he wouldn't allow it since she would die and tells her that the worst day of his life was the day she got powers. Eve leaves and her father orders her to go back, but she doesn't listen.
Eve makes herself coffee at her tree house and browses her phone while looking at the view. Later in the day, Mark runs into Eve, and she realizes that she would be helping him today.

Mark told Eve about his breakup with Amber, which she sympathized with.
Mark tells Eve what happened with Amber, which she empathizes with. He says he doesn't know who he has to be, and she says that the same had happened to her. She tells him that a lot had changed for her as well and she felt she had upgraded since living with her parents.
Later, Mark and Eve hear an explosion and Eve tells him that they should call Cecil. He tells her that it wasn't their problem anymore, since she had run away from Rex and being a superhero. However, she tells him that she didn't ignore the world when it needed her. He says that the world was fine without him, but she tells him that he should do something to help and leaves.
As they flew, Eve tells him that she was glad he came to help, but he tells her that he was only there to make sure she didn't get hurt. Mark saw Nolan being crushed by the creature and raced forward in order to help him.
As Nolan was about to be eaten, Mark punches the creature and sends it flying. Eve gets called by Debbie and asks what was happening. Nolan awoke and Mark happily told him it was about time they teamed up together. When the creature rose, Cecil tells Eve not to help them and get to Guardians HQ.
The Guardians watch the transmission as well. Dupli-Kate suggests going to help them, but Rudy tells them that they needed to follow Cecil's orders and stay in the bunker since the battle was beyond their capabilities. Black Samson agrees, but Eve flies in, asking what was happening. Rex tells her that Omni-Man was fighting him, so Rudy says that he hopes Mark lives up to his name.

Mark told his friends how he was doing at a restaurant.
Mark's friends ask him how his mother is doing, and he tells them that it wasn't good. He doesn't know what to say and tells them that he felt empty inside, and nothing seems real. He asks if they can talk about something else, but William tells him that everybody in the whole world was talking about it, which angers Eve and Amber. Mark gets a call and leaves as Cecil tells him he needs him. Cecil tells him that something was flying towards them from deep space.
As Mark leaves, the whole restaurant shakes, and Eve tells Amber and William she was Atom Eve, which surprises William. However, neither Amber nor William recognized her, much to Eve's dismay.

Fearing for his safety, she quickly left the hospital while yelling that Mark needed her help, causing her parents to realize that Mark was actually Invincible.

But her efforts are futile.
Rushing to Mark's location, Eve fought Conquest despite him warning her she was outclassed.

Atom Eve cheats death.
As she lay barely conscious, she soon floated in the air and the icon of an atom appeared as her body was restored.

Mark brutally beat Conquest to near death before limping over to Eve, wondering what had happened. Cecil and a few other heroes then arrived on the scene.
Post Invincible War/Advent of Conquest[]

Mark and Eve enjoying well deserved rest after the last week.

Much later Eve and her colleagues attended Rex's funeral, where she was too upset to talk about her ex-boyfriend. Mark catches up with her, and she sadly admits she wasn't able to get enough time with Rex, and admitting how sad it is to miss someone despite how they became at first and growing up to be role model.

Thanks to fate, Mark gets lucky.
At night, Eve and Mark undress, and have sex once more.
