The Perfect Dark universe (パーフェクトダーク, Perfect Dark) refers to the Super Smash Bros. series' collection of properties that hail from the Perfect Dark series of first-person shooter games developed by Rare. Due to Rare's sale to Microsoft and resulting lack of presence on Nintendo platforms afterwards, Perfect Dark only received limited representation in Smash.

In Super Smash Bros. Melee

The Cloaking Device item is based on Perfect Dark. Additionally, the Motion-Sensor Bomb in the Japanese release of Melee is based directly on its Perfect Dark appearance. The international releases of Melee redesigned the item to resemble its appearance from an earlier Rare game, Template:Iw, which was the game Perfect Dark had been based on in terms of gameplay and engine. Both items' references to Rare properties are minimized, with their games of origin listed as "TOP SECRET" in the Western releases, and the references to Perfect Dark in the trophy description removed entirely in the American version. All versions still list the game in the credits sequence, however.

Later Smash games redesigned the Motion-Sensor Bomb and treat it as an original Super Smash Bros. series property. The Cloaking Device was removed entirely, although invisibility is still present in certain modes such as Special Smash or by using a Boo in Smash Tour.
