POWERHOUSE IV

Franklin has assumed several aspects over the years as his powers developed from a very young age. In Fantastic Four (1st series) #228, a portion of his power transformed a man into the super-powerful Ego-Spawn. In issue #245, Franklin aged himself to adulthood to better control his powers, dubbing himself Avatar. The adult Franklin returned himself to his true age, with psi-blocks in place to prevent his powers from developing until he was old enough to handle them. However, this only led to Franklin manifesting powers through his subconscious, and he joined Power Pack as Tattletale in Power Pack (1st series) #24.

Franklin was once taken into the future by his grandfather and returned as a teenaged warrior named Psilord. Besides his mental powers, he made use of a heavily-equipped psi-armor stored in a subspace pocket. This timeline was later undone by Hyperstorm, reverting Franklin back to a child. These events covered Fantastic Four (1st series) #376-413. At one point, Psi-Lord's powers became unstable and he manifested multiple bodies for himself as Psi-Lord, Tattletale, Avatar, and Ego-Spawn simultaneously, in Fantastic Force (1st series) #10.

After the Psi-Lord ordeal, Franklin retained his immense reality-warping powers as a child, such as when he created the Heroes Reborn universe. His abilities burnt out during the Abraxas Saga in Fantastic Four (3rd series) #49. Years later, his time-travelling doppleganger helped restore his abilities in Fantastic Four (1st series) #574. After Secret Wars, Franklin used his powers to help restore the multiverse, but they discovered his powers were finite. The more he used his powers, they would eventually vanish entirely. When they did, in Fantastic Four (6th series) #25, Franklin's X-gene disappeared with them. Supposedly, Franklin was never a mutant but instead a cosmic mutate who subconsciously imbued himself with an X-gene out of a desire for community.
