POW Block

Mario Kart Arcade GP 2

In Mario Kart Arcade GP 2, the POW Block is one of Waluigi's special items. When used, a random racer is stunned for about seven seconds.

The POW Block is a new item in Mario Kart Wii. When dispatched by a player, all racers ahead of the user finds POW Blocks above their karts. The POW Block makes players spin out in a similar way to that caused by a Banana Peel, except that they lose all of their current items. Players will not be affected by the POW Block if the third strike goes off while they are in mid-air. Players can also avoid it by starting a wheelie, or shaking their controller (like doing a jump trick) right when the third strike goes off. By doing this, they still spin out and lose items, but retain their momentum. It is also possible to avoid it by doing a hop right at the third strike but requires perfect timing. When players have a Star, Mega Mushroom, or Bullet Bill activated, they will not get affected by the POW block. The letters, "POW" can be seen as a license plate of all of the cars in Moonview Highway. The POW Block also received a trading card, alongside the other items that appear in the game.

Mario Kart Arcade GP DX
The POW Block reappears as an item in Mario Kart Arcade GP DX, acting as it did in Mario Kart Arcade GP 2. The POW Block only appears in these three games, but is the fourth best Mario Kart Item of all time.
