is a corrupt scientist the Saurians hired in "Beaks vs. B.R.A.W.N." to create a flotation device. When the Saurians refused to pay him for his work, he attempted to sell the machine to the highest bidder instead. The highest bidder turned out to be Chameleon, who took the device and left Swindle with a suitcase full of newspapers. A running gag has the Doctor insisting that his name is pronounced "Swindel". Baron Von Licktenstamp (voiced by David Hyde Pierce) is a German hunter who owned his own island. He captures Wildwing, Tanya and Duke and hunts them. Baron Von Licktenstamp had robotic animals to help with his hunt. He collaborated with Dragaunus, giving him the Solaranite substance in exchange for the hunt.
