Zin Vathek, also known as Zin the Unmovable, is a main character along with Estelle Bight and her friends in the The Legend of Heroes: Trails in the Sky trilogy.
Zin is very huge—which many characters note when they first see him, and his sense of clothes obviously is shown from his descent from the The Republic of Calvard. He wears a yellow scarf over his neck, has a bottle of alcohol for himself to drink, and he has brown hair with some sides sticking up. His weapon of choice are his gauntlets to greatly enhance his martial arts.
Zin's personality is one of that of an honorable man as he helps Joshua Bright and Estelle Bright just because he wanted to help out a couple of good friends of his. He is very chappy with his fellows and he loves to drink a lot. He stills acts like a big brother to everyone despite his excessively huge and scary stature. He is also fond of comely lasses used to help the party out one time.
- Zin's English voice actor, Patrick Seitz, is the same voice of Dogi, a main character from another Falcom series called Ys.
- Initially when the Trails series was localized, his name was changed to Zane with no concrete reason.
