Captain Vole

Captain Vole used to be a Jägermonster, but he was kicked out of the club for unspecified reasons, some time after the wild Jägers split off from the main group. He has nothing but hatred for House Heterodyne, and would very much like to see Agatha dead; he holds loyal Jägers (or, as he puts it, "slaves") in the utmost contempt. Whether this is a consequence of his disgrace or the reason for it is not yet known.

He appears to be confined to Mechanicsburg, possibly in order to keep him separated from his former companions who aren't allowed in.
