The POW Block returns in Super Smash Bros. Brawl in one of the stages based one of the games it actually appeared in (they didn't appear in Super Mario Bros.), namely the stage Mario Bros. This time around, the block deals no damage, but it causes grounded characters to bounce upwards (which interrupts charging smash attacks and the like). It also lands a hit on every grounded enemy on the stage, and disappears in three hits (returning after a while).
