In Super Smash Bros. Ultimate, various situations can cause some things to be disabled.
Stage restrictions
Certain stages prevent certain items, Assist Trophies, or Poké Ball Pokémon from appearing. Sometimes this is a reference to something (e.g. Alucard not appearing on Wii Fit Studio because vampires don't have reflections in mirrors), technical issues (e.g. Hotheads and Bombchus not pathing properly because of moving surfaces), or to prevent unfair scenarios (e.g. Nikki's drawings being hard to see on dark backgrounds).
Items
- See /ItemStage for a table.
Assist Trophies
- See /AssistStage for a table.
Poké Balls
- See /PokeStage for a table.
Conflicts
Some items, Assist Trophies, or Poké Ball Pokémon can restrict other items, Assist Trophies, or Poké Ball Pokémon from appearing. Sometimes this is because their effects overlap (e.g. Devil and Squid Sisters manipulate the camera, but in different ways) or to prevent unfair scenarios (e.g. Victini granting a Final Smash to someone while Togepi darkens the screen).
Items
- Only 1 of the following can spawn at a time: Smash Ball, Sandbag, Boss Galaga, Cucco. They can all exist at the same time, but there will only ever be one of that item.
- Smash Balls will prevent Black Holes from spawning. All currently spawned and active Black Holes will be deleted when a Final Smash is used.
- Smash Balls will prevent the third Dragoon/Daybreak Part from spawning. A third Dragoon/Daybreak Part will prevent the third Daybreak/Dragoon Part and Smash Balls from spawning.
Assist Trophies
Assist Trophies that can't appear when certain Assist Trophies are present.
Poké Balls
Togepi, Palkia, Victini, and Zoroark can not appear at the same time. All other Poké Ball Pokémon can appear with others.
Assist Trophy/Poké Ball
Assist Trophies that can't appear when certain Poké Balls are present and vice versa.
Other conflicts
Things that aren't items, Assist Trophies, or Poké Balls that are restricted when certain Assist Trophies, Poké Balls, or other items appear.
