List of Super Smash Bros. Ultimate glitches

This is a list of glitches in Super Smash Bros Ultimate. All names are conjectural unless otherwise specified.

Glitches

Bigmin

If the player throws Pikmin at an opponent's Mother Brain Assist Trophy as Olimar, the Pikmin will grow in size along with Mother Brain. However, these giant Pikmin are only different on a cosmetic level, and will return to normal size once they either fall off Mother Brain or Mother Brain vanishes.

Gale Stab crash

If the player uses a Mii Swordfighter with the following moveset:

• Neutral Special: Shuriken
• Side Special: Gale Stab
• Up Special: Stone Scabbard
• Down Special: Reversal Slash

Then uses Gale Stab while Duck Hunt's Wild Gunman move is active, the game will crash and reset to the home menu.

Indefinite Assist Trophies

To perform this glitch, both the player and at least one opponent has to be playing as Isabelle. Then, they need to wait for an Assist Trophy to appear, and both grab it with their Fishing Rod special move at the same time. If done correctly (with one character reeling it in while the other's line is still attached), the player who successfully reeled in the Assist Trophy will continuously keep spawning copies of the character until they get hit, pushed into a blast zone or KO'd.

This does not work with a few Assist Trophies (like the Squid Sisters) and does not spawn in clones of a few others (like the Moon from The Legend of Zelda: Majora's Mask).

The glitch can also be performed with other items as well. If the player does the same thing with a Warp Star, they'll be trapped and unable to take damage, whereas doing the same trick with a Hammer causes it to do no damage and removes the effect of the lower blast zone.

As of the version 2.0 update, this glitch has been fixed.

Joker Classic crash

In Joker's Classic Mode, if Joker finishes a battle with his Final Smash, the game will crash. This is because Joker's Final Smash usually creates a separate victory screen if he ends with his Final Smash; however, the screen does not appear in Classic Mode.

Piranha Plant single player data corruption

Warning! Performing this action may corrupt your game's save file.

If the player plays as Piranha Plant on a digital copy of the game, then sets a record in All Star Smash, there is the possibility the game will crash and erase all the save data. This has also been reported in other single player modes like Classic Mode, and may come from the game not expecting an additional character to have data associated with it. The same type of issue has also been reported with Duck Hunt and Mii Swordfighter.

Shadow characters

This glitch turns playable characters, Assist Trophies and items into shadows, reminiscent of Dark Link from Super Smash Bros. Melee, while leaving the stage and backgrounds untouched. To use it, the player needs at least one third party controller without gyro/motion control functionality, and to perform one of the two methods outlined below:

The original method

1. Make the Pro Controller player one, and the third party one player two.
2. Start the game and begin a Sudden Death Match with the third party controller
3. Do the same with the stage and character selection
4. Once the match starts, go to the Home menu and select Controllers
5. Change the order and make the third party controller player one
6. Go back to the game, and use the third party controller to select a character
7. Back in the game, pause and press down on the right joystick. This turns the screen black or blue

Then simply press down again to activate the glitch.

The simplified method

1. Start Smash with either the Joy-Con or Pro Controller
2. Then return to the Home menu, and select the Controllers icon
3. Choose Change Grip/Order
4. Connect a third party controller without motion control but with clickable Control sticks (like Hori's Wired GameCube controller) in the first slot
5. Then go back to the game
6. Begin a match in any mode
7. Then pause the game, and choose Camera Control, followed by clicking the left stick

If performed correctly, everything will turn black and the glitch will be activated.

Slingshot crash

For this glitch, the player has to use either Villager or Isabelle, with their opponent using the other character. Then, they need to use their Slingshot special attack on their opponent, and their opponent needs to catch it with Pocket. Once that is done, if the other player releases the Slingshot attack afterwards, the game will crash. This glitch has been fixed as of update 2.0.
