From Nitendo's classic video game comes the Super Mario Brothers collection of figures. A POW Block (occasionally POW and standing for Power Block according to The Super Mario Bros. Super Show!) is a common block in the Mario franchise. In all games they appear in, their effect when thrown to the ground or hit in the air will cause a large earthquake, 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. Most POW Blocks are a metallic blue, but some POW Blocks are red.
