The yo-yo glitch refers to a glitch in Super Smash Bros. Melee done using Ness's yo-yo. It can be used to attack or grab with near limitless range or attach certain single-hitbox attacks to Ness's body. The discovery of the glitch was a collaborative effort between VilNess, LonelyNess, and Dan Smith, and was spurred on by an innocuous video of an unknown Japanese player accidentally dropping a yo-yo hitbox.

The glitch can be performed in all versions of Melee.


Ness's up smash consists of 3 states each with its own hitbox: outreaching, spinning, and swinging. The yo-yo glitch drops the last hitbox of the up smash onto the ground and leaves it there until Ness gets KO'd or uses a non-projectile attack.

How To Perform[edit]

Ness's up smash must first be used and charged up slightly, then hit any opponent or damageable object while in its spinning state before being released. The yo-yo can't hit anything after it is released into its swinging state, although the outcome of the glitch is not affected if it does so while in its outreaching state.

This glitch works with down smash accordingly but requires that said down smash attack be canceled in its ending frames by an attack or effect (such as a Mushroom).


  • Deadline: If Ness uses any non-projectile attack (including a grab) after performing the yo-yo glitch, any characters or damageable stage elements between Ness and the location where the glitch was performed will be hit by said attack. If a grab is used, then only the target closest to Ness will be affected. This followup technique to the yo-yo glitch was discovered by LonelyNess.
  • Thunder Jacket: After performing the yo-yo glitch, if the player blasts with PK Thunder 2 against a floor or a grabbable ledge, the hitbox of the move will be attached to Ness' body. Besides hitting opponents and destructible stage elements, it can also clash with opposing attacks. This followup technique to the yo-yo glitch was discovered by Simna ibn Sind.
  • Spike Jacket: If the player uses Ness' down aerial and lands immediately after its hitbox comes out (which can be done by DJCing or SHFFLing), it will be attached to his lower body, meteor smashing opponents on contact. This followup technique to the yo-yo glitch was discovered by MasterofFlames.
  • Star Jacket: Similar to the Spike Jacket, the hitbox of Ness' up aerial will be stuck to his upper body if he uses the move and lands after the hitbox comes out. It was also discovered by MasterofFlames.
  • Toy Jacket: After performing the glitch, if Ness uses an up smash or down smash on a disappearing platform (such as the awnings in Onett) and times it so that the platform disappears right as the yo-yo comes out, the hitbox of either move will be attached to his feet, causing either weak or strong yo-yo knockback based on the timing of the setup. This followup technique was discovered by Earthbound360.
  • Kirby Jacket: If Ness is Inhaled and spat out by Kirby after performing the glitch, the hitbox of Kirby's star launch will be attached to Ness' lower body. This followup was discovered by Fisac.
  • Throw Jacket: If any other character throws Ness into a wall or ceiling after he performs the glitch, the hitbox of said throw will be attached to Ness body, damaging opponents on contact. Interestingly, KOing them in this way yields the Dead-Weight KO bonus. This followup was discovered by Kahnu.


After using the yoyo glitch, certain other attacks can be used to replace the yo-yo hitbox with the hitbox of the attack used. The rules of the regular yo-yo glitch still apply when using a jacket.

If any non-projectile attack other than the ones listed is used to hit all targets between Ness and the location this glitch was performed, the jacket will be transferred to the opponent, allowing for near-limitless range.
