Trivia

 * According to its trophy, the Motion-Sensor Bomb originates from "TOP SECRET". It actually first appeared in Rare, Ltd.'s GoldenEye 007.
 * In GoldenEye 007, the Motion-Sensor Bomb did not have the green aura surrounding it when activated; this effect was added exclusively for Super Smash Bros. Melee.
 * In the beta version of Super Smash Bros. Melee, the Motion-Sensor Bomb was actually a Proximity Mine from Perfect Dark. It is unknown why the item was changed to the Motion-Sensor Bomb from GoldenEye 007, although, considering that the Motion-Sensor Bomb is listed to have first appeared in "TOP SECRET", it is possible that Nintendo performed these mysterious actions to avoid copyright-related threats from Rare. Its name in the PAL version is also "Proximity Mine".
 * The beta version Motion-Sensor Bomb is the actual bomb used in the Japanese version of the game.
