Woodchuck (ウッド・チャック) is a thief who is the last member to join Parn's group. Woodchuck has spent 20 years of his life in prison, and laments the loss of those years.

He certainly knows a lot of the tricks of the skullduggery trade, including loaded dice and knife throwing. He actually makes himself very useful once Parn releases him from the dungeon of Fortress Myce.

Woodchuck becomes the new host of Karla after Leylia is freed. In the OVA series Woodchuck is taken against his will, but in the manga Woodchuck goes willingly.
