Mighty Meteor
Mighty Meteor is a Special Attack that appears in Mario & Luigi: Bowser's Inside Story.
It is obtained from Doctor Toadley after the 3 Star Cures combine to make the Miracle Cure. 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 enemy 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. After Mario and Luigi destroy the Dark Star's blockade, Dr. Toadley's intern will give Mario and Luigi all 10 Clinic Attack Pieces required to use this move. This attack is very similar to the Smash Egg from Mario & Luigi: Partners in Time.
If Mario and Luigi manage to get EXCELLENT, or if the Meteor defeats all enemies, then the brothers will receive an item (just like the Smash Egg from the prequel). The items are either an Ultra Mushroom, a Max Nut, a Star Candy, or a 1-Up Deluxe.
