List of Classic Mode battles in Super Smash Bros. Ultimate

In Super Smash Bros. Ultimate Classic Mode, each character (except Miis) fights against a predefined set of fighters in predefined stages with their own boss battle at the end. Here is the list of battles encountered for each fighter's Classic Mode. Characters that are assigned either Master Hand or Crazy Hand for their boss battles will fight both bosses simultaneously at intensity levels 7.0 or higher, while characters with allies in their final stage will typically be assigned both Giant Hands outright regardless of intensity.
