Zappa
From Chrono Wiki, a database for the Chrono series that anyone can edit
Zappa is a blacksmith from the town of Termina. Karsh, one of General Viper's 4 Dragoon Devas, is his son. The Zappa from the Home World joins forces with Serge, and when he is united with the Zappa from Another World, they can work together, allowing Serge to forge the Rainbow weapons--the strongest weapons in the game, with the exceptions of the dual Einlanzers and of the Mastermune (in practice). Zappa has a Scottish accent.
