One-Hundred Arms (百手拳 Hyakushuken) is an attack used by Tambourine.
It is an advanced version of the Hasshu-ken.
At King Chappa's temple during the King Piccolo Saga, after mocking King Chappa's Hasshu-ken, Tambourine uses the One-Hundred Arms to attack King Chappa. The struggle ends up with Tambourine dodging the Hasshu-ken and sending King Chappa to a wall, killing him. After this, some of King Chappa's students attempt to avenge him, but they are murdered as well.
