Mikhlo

Mikhlo is one of three Russian gorillas — alongside Peotor and Igor — transformed into super-powered, intelligent apes by the Soviet scientist the Gorilla Man during the Space Race era, first encountered when the Fantastic Four ventured into space in 1963.

Few characters can claim a Silver Age debut alongside the Fantastic Four themselves, but Mikhlo has exactly that distinction — first appearing in Fantastic Four #13 (1963), brought to life by the legendary Stan Lee and Jack Kirby at the very height of Marvel's creative explosion. A fixture in the orbit of Red Ghost and fellow travelers like Peotr and Igor, Mikhlo has kept remarkable company across six decades of Marvel storytelling, surfacing in Fantastic Four, Fantastic Four Annual, and Marvel Comics Presents with four of those appearances earning key-issue recognition from collectors. Thirty-three catalog appearances spanning 1963 to 2025 make Mikhlo a quietly enduring piece of Marvel's Silver Age foundation — the kind of character that rewards the deep-diving fan who wants to trace the full, fascinating sweep of the House of Ideas from its earliest days.
