The POW Block is an item that was introduced for Super Smash Bros. for Nintendo 3DS and Wii U. Whenever it hits the ground, it causes an earthquake to harm opponents if they're on the same floor as the item. They can be used up to three times before disappearing.
This special block first appeared way back in Mario Bros. Hitting it will send enemies flying into the air. You can avoid the shock waves by shielding at the right time or jumping into the air. After being triggered three times, a POW Block will vanish into thin air--don't waste it!
