Professor Milo

Professor Milo is a brilliant, scheming chemist and scientist who uses his expertise to devise elaborate chemical and psychological threats against Batman and Gotham City, earning him a place among the Dark Knight's rogues as a cerebral rather than physically powerful villain.

A cerebral menace who slithered into Gotham's rogues' gallery at the dawn of the Silver Age, Professor Milo made his mark in the pages of Batman #112 in 1957, conjured by the legendary team of Edmond Hamilton and Dick Sprang. Over an impressive span of six-plus decades, this scheming villain has kept some of the finest company in DC Comics — crossing paths with Batman, Bruce Wayne, Dick Grayson, and Commissioner Gordon himself. His appearances across Batman, Arkham Asylum, and even Batman '66 speak to a quietly enduring presence, the kind of deep-cut antagonist that rewards fans who love the full, rich tapestry of the Dark Knight's world.
