Adiposo (a.k.a. "Fat Man," d. 3978) was a mutant who lived beneath the ruins of New York City in the latter half of the 40th century. His actual name has never been revealed. He was a high-ranking leader of the mutant community, and possessed the ability to project his thoughts directly into the minds of others. Further, the Fat Man could pull abstract mental impressions from a target's mind and visually project them. His projections were always filtered through a haze of red light, oftentimes overlapping psychic impressions created by his fellow mutants. Although he was more than capable of physically speaking, his evolved persona preferred communication through telepathy.
