カメレオン·ボナパルト

A French-speaking chameleon who can change shape and color, lives in a forest inside Onimaru's Fortress. He kidnaps Kagetora, Shonosuke and Gerozaemon and turns into a copy of Yaiba to trick the group, but is eventually found out and defeated by the combined efforts of Kojiro and Yaiba.
