The FINAL Final Battle
The FINAL Final Battle (also known as The True Final Battle in PAL regions) is the final single-player event match in Super Smash Bros. for Wii U. The player must choose a character and initially take on Sonic and Mega Man. After one opponent is defeated or after a certain amount of time has passed (one minute in hard), Pac-Man appears, and Mario appears after another one is defeated or time has passed (one minute thirty seconds in hard). Defeating all opponents clears the event.
This event is unlocked by clearing The Final Battle. Completing the event does not unlock any further paths.
