Thunder Bros. is a Bros. Attack used by Mario and Luigi in the game Mario & Luigi: Superstar Saga. The move costs six BP on Modes 1 and 2, and four BP on Mode 3. Luigi learns Thunder Bros. Luigi will start a ball of electricity using Thunderhand. When fully charged, pressing the 
Button results in Luigi jumping on Mario. Another press on Button at this time will send Luigi flying into the air, and one more Button hit will allow Luigi to cast a thunderbolt below him, causing all enemies on the ground some damage. The attack, if performed correctly, always lowers the enemies' defense. The attack can also hit airborne enemies if the second command failed.
Once the attack has been successfully executed eighteen times, the Advanced version is learned. In the Advanced version, Luigi damages only one enemy with more damage. To execute it, the player should press after the initial charge. Before Luigi lands on Mario, pressing the 
button makes Mario step backwards. again to pound Luigi into the ground, and again when Luigi's underneath his target. He'll attack with an electrifying uppercut that can even hit airborne enemies. The Advanced version, when performed correctly, will also lower the enemy's attack power.
