Congo Bill and Congorilla
Congo Bill and Congorilla
Congo Bill (first appearance in More Fun Comics No. 56, Jun 1940: The Search for Africa's Ancient Ruins") is a jungle adventurer who patrols the wilds of the world, mainly Africa. Bill teams with Janu, the Jungle Boy, and following the death of Chief Kawolo, he comes to possess a ring that enables him to inhabit the body of a rare large golden ape named Congorilla.
Superman is aided by Congorilla when Brainiac shrinks the Man of Steel and his friends (Act No. 280, Sep 1961: "Brainiac's Super-Revenge!"). Jimmy Olsen once switches bodies with Congorilla using Bill's ring in order to trap a gang of villains (SPJO No. 49, Dec 1960: "Jimmy's Gorilla Identity!") and later repeats the trick when he is tipped off about a plot to collect kryptonite by scientists in Africa (SPJO No. 86, Dec 1965: "Jimmy Olsen, Ape-Man!").
More recently, Congo Bill and Congorilla are members of the Forgotten Heroes.
