Allen
Allen is a comic book character that first appeared in Invincible #5Allen the Alien is a Unopan, a race of one eyed aliens that escaped destruction by the Viltrumites.
Origin
Allen is the product of a genetic experiment that would create a super Unopan capable of fighting the Viltrumites. Of all the attempts, Allen was the only fetus that survived the experiment with his mind and body intact. The process gave him super strength and speed, amazing healing abilities, high resistance to injury, the ability to travel in space unaided, near-light speed flight and reflexes and telepathy. He was trained from infancy to fight and was never defeated until his first fight with an actual Viltrumite. When his people learned that the experiment was a failure, they scrapped it and Allen became a "Champion Evaluation Officer" and traveled space looking for beings strong enough to beat him so they could be used against the Viltrumites.
Enter Invincible
Early in Invincible's career he was called by his dad to take care of an attacking alien. When Mark got into space he started to fight Allen. During the fight Allen was saying strange things about having a champion and Mark being a replacement. Eventually Mark asked for a break and then an explanation. It turned out Allen was actually coming to Earth to evaluate it's champion instead of Urath. Thanks to Mark Allen was able to keep his job and he left for Urath.
When Allen returned to the Coalition of Planets he was shocked to hear there was a Viltrumite on Earth. He came back as quick as he could to warn Invincible. Invincible explained that his father was the Viltrumite and had already left Earth. Allen was shocked and confused because a Viltrumite has never done anything of the sort. He explained that the point of the Coalition was was to halt the expansion of the empire. He saw this as an opportunity to strike at the empire. He left Earth and returned to the Coalition.
Home Again
After Allen left Invincible for a second time he returned to his home on Talescria, capital of the Coalition of Planets. Allen immediately told the good news to the council and they were as excited as he was. He left the council and went to his girlfriend's apartment. Telia, his girlfriend, is another species and a very sexual one at that which proves troublesome for Allen whose people have forbid any form of physical love. Allen eventually breaks down and allows himself this moment with Telia. Afterwards Allen and Telia went out to eat where Allen enjoyed some of his favorite food. During the meal a Viltrumite scouting party attacked Allen. The group demanded to know everything about what he told the council but Allen denied them anything they didn't know and the party quickly eviscerated him. Luckily Allen was saved and put into a statis pod that allowed him to heal.
After months of healing Allen awoke and accidentally ripped apart of the machine with his newfound strength. Shortly after a nursebot gave him a physical Thadeus, head of the council, entered and revealed that Allen's body and changed and adapted to his recent beat down making him near or at Viltrumite power levels. Allen questions this because no clearcut power level has ever been found for a Vitrumite. Thadeus asks for the nursebot to leave and reveals he is in fact a Viltrumite rebel. He goes on to say that Invincible may be the key to ending the reign of their empire. However, he explains that Allen must only report to him now because he believes there may be a mole in the council.
Powers & Abilities
In addition to his super strength and speed, amazing healing abilities, high resistance to injury, the ability to travel in space unaided, near-light speed flight and reflexes, telepathy and fighting abilities, Allen has discovered that he has another power. After being beaten past the limits of his body by three, fully trained Viltrumite warriors, Allen didn't die. Instead he healed and came back stronger than ever. He says that for some reason, whatever doesn't kill him, makes him stronger, and since he already survived something that should have killed him, maybe nothing can. He also speculates that since he may be "unkillable", he might be immortal. After coming back from his beat down by the Viltrumite trio, Allen is noticeably bigger and more muscular, but otherwise looks the same.
A Favorite of Fans
Despite Allen's few appearances he is widely considered a favorite character by Invincible fans. Even Robert Kirkman himself has stated Allen is his favorite and will never die. He has even joked about giving Allen his own ongoing title.
