Demon Brothers (Earth-2356)

The Demon Brothers, Gozu and Meizu, were two rogue Jedi and bounty hunters from Kirigak that assisted Zabuza Momochi in defecting from the Jedi Order. They subsequently worked with Zabuza in assassinations to earn enough funds for a second attempt at the life of Master of the Order Yagura Karatachi.
