The Poltergust G-00 (オバキューム, Ghost Vacuum), known as Poltergust 5000 in Super Smash Bros. 4, is Luigi's Final Smash in Super Smash Bros. 4 and Super Smash Bros. Ultimate, replacing Negative Zone from Brawl. The Poltergust G-00 is also used in his grab in Ultimate.
As a Final Smash
In Super Smash Bros. 4, when performing this move, Luigi starts by trying to trap opponents and items close to him inside the vacuum. Upon activation, Luigi will automatically sweep the vacuum's suction around him radially - a couple sweeps in front, once behind, then a few more in front - remaining in place for the move's duration, even when used in the air. If any opponents are caught in the initial pass, they receive up to 30% damage before Luigi shoots them out upward diagonally, causing an additional 10% damage and tremendous knockback. Opponents caught will receive the same amount of damage regardless of the time they were sucked in (their percentages increases faster to compensate). Some types of items can be shot out at the end of the move, further damaging opponents as they travel and it is possible to pick them up afterward. Foes sent flying will potentially collide with each other (excluding Team Battles), also causing even more damage. If no opponents or eligible items are caught, the Final Smash will fail. It can't suck in opponents behind solid walls. If used in midair, Luigi will bounce upwards once the move ends to aid recovery.
In Super Smash Bros. Ultimate, it is renamed as it now uses the design of the Poltergust with the same name from Luigi's Mansion 3. It remains functionally identical except that there is a much longer time between the opponents being shot out.
As a grab
In Ultimate, the Poltergust G-00 also acts as Luigi's grab and grab aerial. It is a fairly unconventional grab aerial, as it can't be used as a tether recovery; however, unlike other grab aerials, the plungers shot by the Poltergust are projectiles that will slowly fall down after the move is used with a weak hitbox active.

A ghost-sucking vacuum cleaner created by Professor E. Gadd. In Luigi's ghostly adventures, it's the only thing standing between him and complete terror. In this game, it sucks in enemies, damages them, and then fires them diagonally upward. If it's used in an area with no ceilings, you might send them soaring right off the screen!

Luigi's trusty tool, the Poltergust 3000. This isn't your neighbor's boring, old vacuum—the Poltergust 3000 sucks up ghosts! It also can find them when they are hiding and can blow them around a room! Why doesn't every family own one of these, I wonder...
Unlike your run-of-the-mill vacuum cleaner, this one sucks up...ghosts! And it doesn't just suck them up - it blows them around, draws them to you, and even helps you find them when they're hidden. Talk about convenient! No home should be without one. No Luigi should be without one, either.
The Poltergust 5000 debuted in Luigi's Mansion: Dark Moon, where it was an upgrade of the Poltergust 3000 that was used in Luigi's Mansion for the Nintendo GameCube. It was found by Luigi in the Gloomy Manor inside a car. Luigi also needed to find the Strobulb and the Dark-Light to help him on his quest. Poltergust 5000 is Luigi's weapon for the entire game, constantly gaining upgrades as Luigi collects money throughout the game.
The Poltergust G-00 formally debuted in Luigi's Mansion 3, 11 months after first appearing in Ultimate. Like in Smash, it can shoot plungers that can be used as projectiles or to pull objects towards Luigi. A later upgrade to the Poltergust via an electrical socket allows its suction power to increase to its maximum, referencing the Final Smash with the lightning effects that show up when performing the move.
