Zepet Roughknight (ゼペット・ラグナイト, lit. Geppetto Ragnite) is a character from Wild Arms and Wild Arms Alter Code: F, who raised Rudy as his grandson and brought him on all of his adventures when Rudy was a small child. He also taught Nicholi about ARMs. Before the story begins, he is already deceased, leaving Rudy a young orphan.
The little screentime he has is mostly during Rudy's flashbacks, though his character model is that of a generic old man that could found in any town. His gravemarker has a pendant shaped like a shard of medal hanging on it in the intro of Wild Arms.
Before the game, he borrowed the book "De La Metallica" from Curan Abbey using the ID "Z. Roughknight", but failed to return the book before his death. When Jack and Cecilia go to the Abbey in search of the book, Trish asks Jack and Cecilia to bring the book back, and gives them his ID.
At the end of Alter Code: F, Rudy waves at his grave before running off to catch up with Jack and Cecilia. The ending/credit movie also has the gravemarker featured in the first seconds.
- As his name is meant to be Geppetto, his relationship with Rudy is meant to be an allusion to Pinocchio, with Rudy, as a Holmcross, taking the role of the puppet himself.
