Cargo

Cargo is a kind of carrier that hovers above the ground. They are used to transport heavy objects by the Subspace Army.

Wario's Cargo
Wario's Cargo is Wario's second vehicle in Super Smash Bros. Brawl, (the first one being his bike) It has a piece of metal outfitted on the side that resembles Wario's mustache.

Wario is seen driving this vehicle in the Subspace Emissary. He uses it to carry the trophies he captured and collected (namely, Ness and the princess not rescued by Kirby). On his way through a hill, he spots Luigi, who had been defeated and trophicated by King Dedede. Upon taking Luigi's trophy, Wario is attacked by Waddle Dees. He drops the Luigi trophy into the Cargo, which King Dedede then steals and drives off with.

King Dedede later uses the Cargo's mechanical claw to snatch the trophies of either Mario and Pit or Link and Yoshi. Kirby comes however, and slices off the claw, freeing the duo. King Dedede, angered, turns the Cargo around, giving Link or Pit the oppertuinity to shoot an arrow into it, thus causing it to slow down. Mario, Pit, Kirby, Link, and Yoshi proceed to chase after King Dedede.

The Cargo is then seen parked in front of the entrance to a large cavern that leads to King Dedede's Castle, possibly because King Dedede couldn't fit it into the cavern. It is not known what happens to it afterwards.

Bowser's Cargo
Bowser used a Cargo to steal and transport Donkey Kong's Banana Hoard. Bowser's Cargo has two Bullet Bill blasters. They managed too get away, but the Koopa Troop's Bullet Bills were destroyed. It was last seen where DK and Diddy Kong saved the bananas.

Trivia

 * The long claw on the end of Wario's cargo when not used resembles a scorpion's stinger.
