Angstrom Levy

Angstrom Levy is a fictional character, a comic book supervillain in the Image Comics series Invincible. His first appearance was in Invincible #16. He was created by Robert Kirkman and Ryan Ottley; his mutated form was designed by Cory Walker.

Character History
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 supervillains 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 travelling 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 the murderous doubles of Invincible. In the end, Levy's plan fails as the Earth, though devastated, was not conquered. He escapes, 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'.
