Knockback Bros.

Knockback Bros. is one of Luigi's Bros. Attack during the events of Mario & Luigi: Superstar Saga. It is based off of Mario's Mini-Mario form. The move costs five BP on Modes 1 and 2, and three BP on Mode 3. Luigi smacks Mario with his hammer, making him a ball, and hits him like a golf ball. The buttons pressed are to whack Mario,  again to send him shooting toward an enemy, and  to do damage to the enemy.

After successfully executing the attack forty-three times, Mario and Luigi learn the Advanced version. In the Advanced version, more controls are added. The controls for the standard version are the same, but to execute the Advanced version, must be pressed immediately after the first  press. Then the controls are to hit Mario and  to do damage, which repeats indefinitely. In the 3DS remake, however, the move has been nerfed, as Luigi can only hit Mario up to five times for an "Excellent!" rating (Doing so only once gives a "Good!" rating, and four times gives a "Great!" rating.), and Luigi winds up for the last hit.

This move is also used by the Hammer Bros. in Mario & Luigi: Partners in Time, where they perform it exactly the same as the Mario Bros. did in Superstar Saga. They use it when under influence of the Shroobs mind-control helmets, and are only able to perform it together with both Hammer Bros. standing. Occasionally, their hammers will break, causing the other Hammer Bro to bounce towards Baby Mario and Baby Luigi. To dodge the attack, the Baby Bros. must jump over the Hammer Bro that was hit at them.
