This is the list of known changes in version 1.2.0 of Super Smash Bros. Ultimate.

Universal

  •   Invisible Bomb glitch has been removed. Link is mainly affected by this change, though Young Link and Toon Link are technically affected as well.

Kirby

  •   After copying Pac-Man's Bonus Fruit, Key will no longer be discarded when it is recycled.

Luigi

  •   The plunger from his grab aerial now disappears when used while crossing a platform instead of getting stuck inside it.

Villager

Greninja

  •   A visual glitch with Greninja's screen KO has been fixed.

Pac-Man

  •   Bonus Fruit's Key will no longer be discarded when it is recycled.
  •   The universal change removing the ability to Z-drop items out of hitstun reduces Pac-Man's ability to get out of combos when holding a Bonus Fruit.
  •   Dash grab changes Pac-Man's facial expression like his other grabs.

Isabelle

  •   Dream Town Hall grants Isabelle invulnerability after the last hit.
  •   Created the Slingshot Crash glitch where if Villager or Isabelle Pocket one another's slingshot from a Pocket, the game will crash.
