Burst Grenade is Sheik's Side Special Move in Super Smash Bros. 3DS/Wii U. Sheik throws a grenade, and after a while she will pull the pin, making it explode.
The move can be charged, and the longer Sheik charges it, the farther the grenade will go and the later the pin will be pulled. When the grenade explodes, it will create a vacuum effect, pulling anyone it catches toward the center of the explosion.
