His origin a complete remain a mystery, while he apparently came from El Nido and naturally fell into the service of Viper Manor given his physique and mindset were both suited for combat. Something adverse happened to him in the past, but this is never mentioned. He wore a helmet at all times, and little else to show off his muscles. when Serge tried to infiltrate Viper Manor via Shadow Forest, he blocked the party off temporarily by challenging them in battle. Later on, he fought with the party again at Mount Pyre. After the Fort Dragonia double crossed occurred, he helped Karsh take Viper back for recovery. He then wound up on the S.S. Invincible, where he preferred to sleep when not traveling. He often muttered in his sleep, dreaming of something to eat (his utterances included "YUMMY!"). He then accompanied Serge in the fight against the Time Devourer.
while Zoah remains a complete mystery concerning his past and what lies under the helmet. He also probably has a deep and baritone voice, implied by the fact that his dialogue is displayed in all capitals in Chrono Cross. Zoah has a tendency to SHOUT, presumably because he never takes his helmet off.
How to Join
After finishing the Dead Sea, go to the back room of the shop in Termina (Another World) and choose Zoah to help you rescue Riddel. If you choose Karsh, Zoah will join you later after Riddel is rescued.
