Vacuum Helmet

The Headgear is a device used by Fawful in the game, Mario & Luigi: Superstar Saga. It appeared again in Mario & Luigi: Bowser's Inside Story, during the battle against Dark Fawful.

The Headgear has many functions, and is primarily used by Fawful to fly around or hover. The Headgear's nozzle can both shoot fiery balls of energy at Fawful's opponents and vacuum up other things, which are then stored within the Headgear. Mario & Luigi: Bowser's Inside Story introduces more functions, including the Headgear's ability to function independently from Fawful. It is also revealed that the Headgear's nozzle can morph into a kind of basket, inside of which Mario or Luigi can be trapped and drained of their HP. While Fawful is fighting Bowser, he may use his headgear to avoid some of Bowser's attacks or he can revive some of his own HP. The headgear also morphs it's nozzle into what looks like teeth, allowing Fawful to grab onto objects and swing from them. At some point, the headgear will fly above Fawful's head on the top screen, where Bowser can use his vacuum ability to suck it up into his body, where the bros. will fight it. After taking a certain amount of damage, the headgear will explode and cease to exist.

In Mario & Luigi: Superstar Saga, Fawful uses the Headgear to suck up Princess Peach's voice before the onset of the game. He uses the Headgear's fireball ability to battle Mario and Luigi when they come to reclaim Peach's Voice; he then uses the attack to destroy Bowser's Koopa Cruiser. Later, when Cackletta is defeated by the Mario bros., Fawful sucks her soul up with the Headgear and deposits it inside Bowser's unconscious body, thus saving her from death.

Trivia

 * In Mario and Luigi: Bowser's Inside Story, the "head" of the Headgear looks similiar to that of the head of R.O.B the robot.
