Zappa is described as a rough and tough person which later inherits from his son Karsh from his dimensional counterpart in Another World and a very loving husband to his wife Zippa. His desire to find the Rainbow Shell is the most precious to him and his reasons for joining on Serge's group in finding it. If he was in Serge's party at the Dead Sea, Zappa finally shows his grief over the loss of his son Karsh who is among the others were killed in the Dead Sea after three years as well as encountering his dimensional counterpart in Termina in Another World and learns to forge using the Rainbow Shell he had recently found. Zappa was also given along with his wife Zippa high regard from Karsh (when he was in Serge's party) during his visit in Termina at Home World.
Born on the Zenan Mainland, he somehow made his way to El Nido and came into the service of the Dragoons. He probably was a Deva with Radius and Garai; the three tore up the battlefield together. Zappa also cultivated an interest in smithing at this time; he soon met Zippa, his wife, and the three looked far and wide for the Rainbow Shell. They did not succeed in finding it, and after retiring from the Dragoons, Zappa opened his own Smithy in Termina and raised his son Karsh there. He fashioned all kinds of weapons for use with the Acacia Dragoons; his son eventually became a Deva in the same tradition of his father. However, tragedy struck after Lynx led an expedition to the Dead Sea. Karsh was frozen and phased out of time, and never returned; this adversely affected Zappa, whose work was disrupted by bouts of sorrow and loss of motivation. Regardless, Zappa pressed on in his craft until 1020 A.D., when he finally shut down the smithy and dismissed his apprentice. He noted that he would seek the Rainbow Shell once more. He met Serge before his journey began, and decided to accompany the boy; along the way, he found his deceased son among the dead in the Dead Sea. He came to grips with his son's death, and also found the Rainbow Shell, which he learned to forge by working with his dimensional counterpart and using the Master Hammer. He planned to open a new smithy after the journey's end.
How to Join
Talk to Zappa in his smithy in Home World Termina. Zappa will have a short conversation with Radius if he's in your active party, but it's not required for him to join.
Zappa is likely named after the American Musician, Frank Zappa, who composed an album called "Hammersmith Odeon". The former describing Zappa's profession, and the latter detailing the Proper Noun of a Greek Smithy. Since the Greeks are famous for the Olympics and, yet again, the motif of the smithing appears, it is no wonder that his techs resemble Olympic events.
