Arm Break is one of Nappa's special moves. By default it is bound to quarter-circle-forward and light, medium, or heavy attack. Nappa will smash the ground with his fist using all of his might. The light variant starts up fastest and does the least damage. The medium variant does more damage over more hits. Nappa will run forward before executing the attack. The heavy variant does the most damage, starts up slightly faster than the medium variant but slower than the light, and costs a half bar of ki. Nappa will run farther and faster during this attack. All hits of all variants of this attack are overhead attacks.
