Blast Box

The Blast Box (爆薬箱, Explosive Box), is a heavy item that appears in Super Smash Flash 2. It appears as a crate with a Fire hazard warning on the front of the crate. The crate can be hit multiple times before it explodes while it will explode instantly when hit by a fire attack. When hit, it will slide across the stage. When a character is hit by the explosion, they will receive a ton of knockback.

The Blast Box in BETA is more tolerant to attacks than the ones in Brawl or Smash 4.
