Feltis (Japanese: フェルティス Romaji: ferutisu) is a minor character who appears in the fifth novel. He's a beast-man-hybrid of a werewolf and something else and a member of the Cult of Shabranigdu. He fights with a long sword. He has not yet appeared in the anime.
He helped assist Balgumon in attacking Lina Inverse and Amelia Wil Tesla Saillune after they interrupted their cult meeting. Just as they had Amelia as a hostage, Xelloss appeared which caused Feltis to fly into a rage and attack him due to an unknown bad history, although it's hinted that it might have something to do with their tussle for the Claire Bible manuscript near Raizeel. Feltis was immediately vaporized into orange powder by Xelloss' Blast Bomb.
