Allen the Alien, or simply Allen, is a major character in Invincible, debuting from Season 1 and onwards. He is the boyfriend of Telia. Born in a Unopan breeding facilities created to replenish his race after the Viltrum Empire nearly eradicated them, and also to act as a defense against the Viltrumites. Although his function as a defense against the Viltrumites was ineffective, he later assumed the position of a Coalition of Planets' evaluation officer, traveling to different planets in multiple galaxies in search of a warrior capable of defeating the Viltrumites. After a close brush with death, Allen gained increased strength and was able to compete with the strongest of Viltrumites. After effectively recruiting Invincible, he managed to bring his father, Nolan, on board so they could work together to bring the Empire's reign of terror to a permanent end.
