Mighty Meteor

Mighty Meteor is a Special Attack that appears in Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. It is obtained from Dr. Toadley after the 3 Star Cures combine to make the Miracle Cure. After Mario and Luigi destroy the Dark Star's blockade, Dr. Toadley's intern will give Mario and Luigi all 10 Toadley Clinic Attack Pieces required to use this move.

When using this attack, Mario or Luigi sends a huge meteorite up into the sky. The player must control one of the brothers with the D-Pad and press the corresponding button when it falls. If the brother successfully pulls off this command, the meteorite crashes into the enemy, thereby inflicting damage, then going back to the Bros. and the attack continues. If the brother fails, the attack stops. This attack costs eight SP to use. This attack is very similar to the Smash Egg from Mario & Luigi: Partners in Time, except the player uses hammers instead of kicking.

After a successful attack, the meteor bursts open and the Bros. receive a random item. The items are either an Ultra Mushroom, a Max Nut, a Star Candy, or a 1-Up Deluxe. This effect occurs even during the Gauntlet fights, allowing Mario and Luigi to effectively use more items than they are allowed, and since Star Candy replenishes SP fully, with some luck it is possible to attack and gain an item every turn, stopping only to refill SP.

In Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, the meteor is now a 3D model that lacks the "?" icon and explodes into confetti when the attack ends successfully. The Special Attack can also lower enemies' attack power and also plays the last few notes of the classic level complete theme from the original Super Mario Bros. when it reveals an item.
