Burst Grenade

Burst Grenade (, Exploding Pill) is Sheik's side special move in Super Smash Bros. 4 and Super Smash Bros. Ultimate. It replaced Chain from Super Smash Bros. Melee and Super Smash Bros. Brawl.

Overview
When activated, Sheik throws a small grenade connected to a chain, presumably the same one seen in Melee and Brawl. The throwing animation involves Sheik throwing with her left hand, spinning around on one foot, then landing on one knee before standing back up. After being thrown, the grenade will activate a vortex effect, pulling any close by opponents in before exploding and damaging said opponents. Holding down the button can delay the explosion for a brief moment. The vortex also steadily deals minor damage over time.

The throwing animation ends before the grenade explodes, which means Sheik can perform in action around the time the vortex activates. This can be useful for positioning Sheik to tech-chase or combo an exploded opponent. Sheik can also be hit before the grenade activates. If this happens, the grenade will fall to the ground without exploding. This grenade can then be picked up and thrown, similar to Hand Grenade. The grenade deals 6-8% damage, but with no vortex.

In Smash 4, performing this move in the air will put Sheik in a helpless state. This effect was removed in Ultimate.

Item Gravitation glitch
In Ultimate, if Sheik uses Burst Grenade when anyone in the match (including herself) has the spirit effect Item Gravitation or Healing-Item Attraction, the grenade will never explode. The grenade will instead slide across the ground at high speed before disappearing, nearly covering the entire length of. Similar to the grenade's behavior when Sheik is attacked before detonating the grenade, the grenade can be picked up and thrown like an item.

This glitch appears to have been added in and is still present in, the latest version of Ultimate.

Customization
Special Move customization was added in Super Smash Bros. 4. These are the variations:


 * 1) Burst Grenade: Default.
 * 2) Gravity Grenade: No draw in effect before explosion and deals less damage, but enemies hit by the blast are knocked towards Sheik, allowing for combos.
 * 3) Skimming Grenade: Grenade bounces on the ground away from Sheik with a controllable timed delay before exploding. The explosion deals less damage, but the bounces can deal up to triple the damage of the regular version's hit and pull.
