Arm Break (アームブレイク, Āmu Bureiku) is a rush attack used by Nappa. Nappa powers up and then charges at the opponent to deliver a powerful punch to their arm, capable of severing it, causing excruciating pain and major damage to the opponent.
Nappa uses this attack during his battle against Tien Shinhan. After powering up to combat the Z Fighters, Nappa chooses to fight Tien first and attacks him, scorching Tien's arm in the process. Nappa then attacks Tien with the Arm Break rush, severing Tien's arm and mortally wounding him.
