Flex Mentallo

Flex Mentallo is a superhero who gained incredible muscle-based powers through a fitness program advertised on matchbooks, becoming the self-styled 'Hero of the Beach.' A parody of Charles Atlas-style bodybuilding ads brought to surreal life, he possesses the ability to reshape reality through flexing.

Born from the boundary-pushing imagination of Grant Morrison and Richard Case in Doom Patrol #35 (1990), Flex Mentallo is one of the most fascinatingly singular figures to emerge from the Copper Age's most experimental corner of DC Comics. A character who feels like a living meditation on the mythology of superhero comics itself, he made his mark sharing pages with icons like Cliff Steele, Negative Man, and Larry Trainor before eventually headlining his own series. Spanning over three decades from 1990 to 2023 — and turning up across titles as varied as Detective Comics — Flex Mentallo is a cult treasure, the kind of character who rewards the curious reader willing to dig into comics' stranger, more philosophical depths.
