Angstrom Levy's History
Origin
Little is known about Angstrom Levy's background; including how and when he developed the power to open up portals to alternate realities. At some point Levy sets out to amass information about the various alternate Earths so as to be able to travel through them more safely. To this end he contacts alternate versions of himself from hundreds of parallel Earths, and convinces them to help him. Next Levy frees the super-villains the Mauler Twins from prison on the condition that they help him create a machine that would allow him to copy the memories of his alternate reality counterparts into his own brain.
With the aid of versions of themselves from other realities, the Mauler Twins are able to construct the machine. Levy is in the process of uploading the memories of his alternate selves when the process was interrupted by Invincible who is trying to apprehend the Maulers. The Maulers are on the verge of killing Invincible when Levy halts the machine to try and stop them, causing it to overload and explode. Unbeknownst to Invincible, Levy survives the explosion but was horribly mutated and suffered internal organ damage all while believing it was Invincible who stopped the machine.
Revenge
Surgeons are able to rebuild and even enhance Levy�??s body but they were unable to correct his monstrous appearance. Levy is left with a burning hatred of Invincible whom he blames for the accident. He is able to discover that Invincible was really Mark Grayson by traveling to realities where his identity is public knowledge.
Levy takes Mark's mother and his toddler baby brother hostage in their home and lures Mark in with a phone message. When Mark arrives to rescue his family, Levy sends him into the Marvel Universe. Levy mistreats his family, tossing the baby (who is caught safely) around and breaking his mother's arms in retaliation for a failed attack with a lamp.
Mark returns but is sent to various other realities, such as one with zombies and some with familiar and not so familiar super-powered beings. On one of his many futile trips back home, Mark learns that Levy intends simply to wear him down and kill him, along with his family. Then he will do the same to all alternate Marks.
Mark, tricking his opponent by waiting on one side of a portal, manages to tackle Levy into an abandoned wasteland of an Earth. Overestimating the success of Levy's enhancements, Mark seemingly beats him to death by accident. Mark is rescued from this wasteland by future versions of his friends, who had traveled through time and space to find him.
Return
At the end of Invincible issue 51, Angstrom is revealed to be spying on Mark as he sits atop his roof, via a small robotic camera. He is showing sitting in a room with many monitors, all with videos of Mark playing, and also with small electrical globes attached in his head. He has adopted a super villain style costume, complete with cape and new scars on his face from the previous encounter with Invincible.
After spying on Mark for a number of months, Levy reveals his plan: gather evil versions of Invincible from other dimensions, and unleash them upon the first Mark's world. While this creates worldwide panic and death, the main goal is to ruin Invincible's reputation and cause him suffering. The world's superheroes unite, some giving their lives to battle and kill most of the Invincibles. In the end, Levy's plan fails as the Earth, though devastated, was not conquered. He escapes and sends the surviving Invincibles to a wasteland dimension, but loses a limb, and upon arrival to the dimension of his doctors, loses their support and is informed that he now 'works for them'.
A few months later Angstrom is allowed to return to the Image Universe and, upon hearing about Invincible's apparent death, decides to live in a suburban neighborhood along with his drones. However, he soon learns that Invincible is not actually dead and in rage heads to Mark's house. Once arriving he waits for someone to arrive the first person being Atom Eve. He quickly detained Eve and wondered whether she had any powers since they had, had no contact. He was very surprised when Invincible suddenly appeared before sending him to the wasteland dimension where only two evil Invincibles remained. While waiting Angstrom talked to Eve who asked him about why he hates Mark so much. Upon hearing Angstrom's response Eve told him how Angstrom's invasion killed her ex-boyfriend Rex-Splode. She states that her life felt ruined, but she didn't go insane, and she swears revenge on him. Angstrom realizes how pointless revenge is and opens a portal allowing Invincible and the last evil Invincible to return. Angstrom apologizes for what he's done and offers to allow the evil Invincible home by opening a portal for him. Instead the evil Invincible decides to bring Angstrom with him to his home dimension where he apparently plans to torture him.
Death
After his last defeat at the hands of Invincible and surrendering after capturing Eve, Levy is taken hostage by a surviving evil version of Mark from another dimension where he is tortured for information on traveling from one dimension to the next. Invincible and Robot travel to said dimension and when they do are shown the horror that Levy is enduring. Robot stuns both Marks and kills the evil one, then kills Levy by slicing off his head, he traps Mark in that dimension, believing him to be too great a threat.
Mark later escapes thanks to the help of the Robot of that dimension.
