Gog was discovered and raised by Kraven the Hunter when the spaceship which he was on crashed in the Savage Land. He took Gwen Stacy hostage by order of Kraven when she, J. Jonah Jameson and Peter Parker were on a mission to find Kraven in the Savage Land, with the help of Ka-Zar. Spider-Man seemingly outwitted Gog when he fell into quicksand, but Gog was in fact rescued by The Plunderer, Ka-Zar's brother. The Plunderer used Gog to help commit crimes, until the creature grew bored and wandered away.
