The GoldenEye universe (ゴールデンアイ, GoldenEye) refers to the Super Smash Bros. series' collection of properties that hail from the GoldenEye series of first-person shooter games which was first developed by Rare. The games are adaptations of the James Bond film, GoldenEye. Due to Rare's sale to Microsoft and resulting lack of presence on Nintendo platforms afterwards, combined with the video game series being based on a movie franchise and thus involving many other copyright holders, GoldenEye only received limited representation in Smash.
The Motion-Sensor Bomb's design in this game is based on its appearance in GoldenEye 007 for N64.
The Motion-Sensor Bomb in all non-Japanese releases of Melee retains its appearance from GoldenEye 007 for the N64, with the PAL version referring to it by its original name, the Proximity Mine. The Japanese release of Melee, however, redesigned the item to resemble its appearance from a later Rare game on the same engine, Perfect Dark. The item's references to GoldenEye are minimized, with its game of origin listed as "TOP SECRET" in the Western releases. Smash games redesigned the Motion-Sensor Bomb and treat it as an original Super Smash Bros. series property.
Despite many rumors, James Bond was never intended to be playable in Super Smash Bros Melee because Sakurai stated that he would difficult to include, not scrapped.
