Rick (Marvel)
From Multiversal Omnipedia
Rick was one of the super-heroes of Earth-238, and one of the last to face the Fury. Rick was in love with Captain UK, and when the Fury broke through to slay the last heroes, Rick put her in a teleportation tube that transported her to Earth-616- but not before the Fury killed Rick in front of her.
Later, Roma changed history, rescuing Rick in the nick of time. Rick and Captain UK, reunited, travelled to the Earth of Sat-yr-nin and eventually overthrew the tyrant.
Comments
Rick was an analogue of Young Marvelman, Marvelman (Miracleman)'s younger partner. Perhaps he was called Young Miracleman?
