Dropchopper

Dropchopper is Luigi's third available Bros. Attack in Mario & Luigi: Dream Team. Luigi obtains the 10 Attack Pieces for this attack on Mount Pajamaja. It costs 7 BP to use this attack, and its damage is given Jump attributes, doing critical damage on enemies weak to jump attacks.

Upon using the attack, Mario and Luigi will run into the foreground, and the Dropchopper will begin floating in mid-air near the Bros. as they run towards the group of enemies. Tilting the 3DS will make the chopper move in the direction the handheld is tilted in. Once the Dropchopper is above one of the bros, the player must press or, depending on which bro the chopper is above. Once Mario and Luigi have both grabbed onto the Dropchopper, it will slowly rise into the air. The player can continue to tilt the 3DS to change the target area below. Once the Dropchopper hovers above an enemy, either or  must be pressed to cause the Dropchopper to drill down into whatever is currently below it with tremendous force, heavily damaging the enemy it directly hits and moderately damaging enemies in the target circle with the impact's shockwave. The attack will fail if both Mario and Luigi cannot grab onto the chopper in time, and if a single Bro manages to grab on, the attack continues as normal but deals minimal damage.

This move returns in Mario & Luigi: Paper Jam, still used by Luigi, and retains its functions, except it is now controlled by the instead of gyro controls. Oddly, if a stack of Biddybuds were hit, the entire stack will take damage all at once.

Mario & Luigi: Dream Team
''Tilt the 3DS left and right to pilot the craft once Mario and Luigi grab on. Jump up with the A and B buttons! If you grab on quickly, you'll fly higher. Press the prompted button when you're above a foe for a devastating slam!''

Mario & Luigi: Paper Jam
''Move the Dropchopper above Mario's and Luigi's head using the Circle Pad. Press A for Mario to grab on and B for Luigi. The faster they both grab it, the higher it goes. Aim for your enemies using the Circle Pad, and press the top character's button to release!''
