The POW Block (standing for Power Block according to The Super Mario Bros. Super Show!) is a common block in the Mario series. In all games they appear in, their effect when thrown to the ground or hit in the air will cause a large tremor on the ground, causing all enemies on screen to get hurt. POW Blocks can be carried and thrown in most games, and some are required for a 100% game completion.
- In Super Mario Bros. Wii the Pow Block is blue instead of red.
