Notes
Some Bosses may not be present until post-launch, particularly if Adventure Mode is not yet available and Nintendo wants to wait to reveal that boss. This also means that Boss Rush and All-Star Boss Rush may be slightly different before all bosses are released.
Some bosses are used in Classic Mode at the end of certain character routes.
