This is Allen the Alien from the TV show. For the comic character, see Allen the Alien.
The Coalition is trying to unite enough worlds to stop the Viltrumite empire. The thing is... no one's even heard of a Viltrumite abandoning their post. It's insane. It just doesn't happen. This could be the advantage we've been looking for. 
History
Origin[]
Allen the Alien is a member of the alien race the Unopians. Allen was born in an Unopian breeding camp due to their borderline extinction at the hands of the Viltrumites. Allen now works for the Coalition of Planets in their battle against the Viltrum Empire.
Background[]
Known only as "Allen", his species, the Unopians, were almost completely wiped out after the Viltrumites destroyed their home planet during their campaign to conquer planets and add them to their empire. The Viltrumites destroyed the Unopians home planet when they could not claim it for empire, due to the Unopians rebelling against them.
After the destruction of their home planet, the Unopians were forced to create breeding camps for themselves to prevent their species' extinction. Allen was born at one of these breeding camps and because of this, never met his own father.
Allen now works as an "evaluation officer" for the Coalition of Planets, a secret anti-Viltrumite alliance dedicated to stop the empires conquest of the galaxy. He travels between planets, challenging them to ensure they have warriors strong enough to defend them against threats.
Whilst working for the Coalition of Planets, Allen would visit Earth several times, actually intending to go to a planet called Urath. Allen would instead going to Earth due misreading his orders and end up challenging Omni-Man, not knowing that he was really a Viltrumite.
Invincible fighting Allen the Alien[]
Invincible fought Allen the Alien only to find out he was testing the wrong planet
Invincible went to space and was attacked from behind. Allen communicated via telepathy and, believing that he was Omni-Man, exclaimed to him that he had shaved the moustache. Invincible fought with Allen, sending him towards a satellite, which was thrown back at him. Mark was punched and teased, told that if that was protecting the planet, then he was sorry for their people.
Invincible took a moment to breathe, and made Allen realize that he was not the same person who had fought him years ago. Invincible sent him crashing into the moon, which only made him laugh. When Invincible told him he only wanted to talk, Allen asks him if he was using his time out, which confused Invincible. However, Allen mentions that he does not make the rules and grabs a rock for both of the to sit on. He tells Invincible that he is an evaluation officer for the Coalition of Planets, making sure that there was somebody capable of defending them.
Invincible told him he did not know what he meant, but Allen tells him that the planet "Urath" was on his list, which makes Invincible tell him that he had gotten the planet wrong since they were on Earth. Allen commented that he was in trouble, and introduced himself. Invincible presented himself, which makes Allen tell him that the name was optimistic, since he believed he was pretty vincible. Invincible is left confused and goes to outer space.
Later, Mark is in space, ready to punch his father, but is met by Allen the Alien. He tells him that when he told the Coalition of Planets he had been going to Earth instead of Urath, they had lost their minds and lets him know there was a Viltrumite on his planet, which was marked for Viltrumite takeover. Mark lands on the moon and tells him to sit down while he explains.
Mark talks to Allen[]
Mark talked to Allen the Alien about his father and defending Earth from the Viltrumites
Allen is confused that Mark is a Viltrumite, but did not work for them and could not believe Omni-Man had just left, since Viltrumites did not give up that easily and were relentless, having destroyed his world when they fought back. Allen literally cannot picture what Mark was going through since his people had to create breeding camps just to stop them from going extinct. He tells Mark that the Coalition of Planets would want to hear about him since the Coalition was trying to unite enough worlds to stop the Viltrumite empire and mentions Mark could be the advantage they were looking for. He tells him that the Viltrumites would come back for him and asks him his plans, to which Mark responds that he'll finish high school, idea which Allen approves of, however, he asks with confusion what high school is.
Appearance[]
Allen is an Unopian, a brick skin colored humanoid with a head that ends in a slight spiked scalp, has small pointed ears and a single large eye on his face with a white sclera and a small pupil. His one eye is protected by a thick brow. Allen's facial features are square shaped and has a strong chin. He has three fingers on each hand, one thumb, one finger in place of an index and middle finger and another finger in place of a ring and little fingers. His likewise only have three thick toes. Allen dresses in a white leotard which exposes his neck and stretches to his wrists and ankles. Over it he wears a tight magenta jacket with an upward facing collar, grey segmented wrist guards and similarly grey segmented ankle guards. He also wears a dark grey belt with with pouches, likely for caring provisions during space travel, and a light grey colored belt buckle.
Personality[]
While devoted to his job, Allen still has a joker attitude and a comic demeanour, evident even when he fights, cracking wits while overpowering Invincible in space. After realizing he had inspected the wrong planet as Invincible pointed out his mistake, he proved to be very friendly, apologised for the assault and struck an alliance with him, later on returning to warn him about the presence of a Viltrumite (Invincible’s father, Omni-Man) on Earth. After hearing Mark’s story Allen was very understanding and connected with him the best he could, sharing how he never met his father, since he was born in a breeding camp which helped to keep his species from extinction after the Viltrumites’ attack on their planet. He also warned Mark that the Viltrumites will surely return to conquer Earth, hence their complete relentlessness in taking over planets. When asked about his future plans, Mark answered he'd like to finish high school, leaving Allen, who wasn't familiar with Earth at all, confused.Attributes
