All-Star Battle: Secret is a single-player event match in Super Smash Bros. for Wii U. In it, the player must choose a character and take on the fighters who were unlockable in previous Smash Bros. games. The first are the first four unlockable characters who have been in every Smash Bros. game, though arranged according to Brawl, Ness, Luigi, Captain Falcon, and Jigglypuff, followed by Dr. Mario, being unlockable in Melee, and the last being Toon Link, R.O.B., and Sonic, who were unlockable in Brawl.


This event is unlocked when Enough with the Kidnapping! is cleared and R.O.B. is unlocked. Completing the event does not unlock any further paths.

Clearing the event on normal or hard difficulty awards an Auto-Healer Tie equipment. Clearing the event on hard difficulty also awards the Shadow trophy on the challenge board.


  • The music used in this event, Credits (Smash Bros.): Ver. 2, normally plays on Battlefield, rather than Onett.
  • Ironically, R.O.B. and Dr. Mario are the only characters faced to be unlockable in Super Smash Bros. for Wii U.
