King Oscar was an anthropomorphic lion and a king in the "goode olde days of Merrie England" on Earth-C. Though mostly a lazy bum, Oscar created the Knights of the Round Table at his wife Jennifer's insistence, as she believed it was the only thing the useless piece of furniture (made by their cousin Elmer) was good for. Oscar occasionally sought the advice of Swirlin the Magician.
- This version of King Oscar, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- King Oscar is a parody of King Arthur.
