Time Diver: Eon Man is a Nintendo Entertainment System video game developed by Atlus for Taito. Despite being completed in 1993, it was never commercially released. The game is completely finished, receiving a four-page strategy guide and review in issue 45 (February 1993) of Nintendo Power. Despite this, the game eventually disappeared from the Pak Watch section and was subsequently unproduced. Eon Man started life as a sequel to Wrath of the Black Manta, according to an interview the Game Developer Research Institute conducted with the game's planner.
