Yango
Yango
The super-intelligent gorilla from Krypton who is the equal to Superboy.
Yango was reared from birth by the "noted anthropologist" Professor An-Kal, who subjected the baby gorilla to "years of intensive-conditional-cybernetic brain-programming" in an effort to prove his "revolutionary 'Genetic Alterance' theory." When Jor-El warned Krypton's Science Council of the planet's imminent destruction, An-Kal was among the few believers, sending Yango to Earth in a rocket to escape the blast at the same moment that Jor-El sends his own son, Kal-El, to Earth. But whereas Kal-El lands near Smallville and is adopted by Jonathan and Martha Kent, Yango lands "in the mountain-fortress of 'Gorilla Country' in Kenya" where he is adopted by a gorilla couple and grows up to be the monarch-protector of a hidden society of powerful and intelligent gorillas headquartered in an 'underground 'Ape City'." It is here that Superboy first encounters Yango while on the trail of some poachers--eventually imprisoned by Yango with the aid of the Boy of Steel (SB No. 172/1, Mar 1971: "The World of the Super-Ape!").
