The Motion-Sensor Bomb is an item in Super Smash Bros. Brawl. This item, if picked up and thrown onto a surface of any kind, will explode when a player (or AI) walks over it. This can be used as a tactical advantage for the players, as they can use it as a trap due to it's small size and explosive qualities. Also in Super Smash Bros. Brawl for the Wii, it is featured as a trophy to be collected. The description reads, "An item that when placed, will detonate when someone gets close. It can be stuck on ceilings, walls, and floors. It doesn't matter who places this thing--it'll explode regardless of who passes by. It's explosive power is high, and it launches players with ease. It's small and lies flat on most surfaces, so it can be difficult to see." The Motion-Sensor Bomb is also included in the game Super Smash Bros. Melee, appearing as an item from the game Perfect Dark, as another trophy. This description reads, "The perfect accessory for ambushes, the proximity has long been a favorite cavort weapon of the Carrington Institute any surface and once armed, detonates with incredible force when it detects motion within it's range. In the frantic world of Super Smash Bros., it doesn't take long for it to go boom."
