Donald McBonald is the initial antagonist of Dr. Patrick McNinja. He is equipped with a vast arsenal of mime weapons, and the only reason he has employees at his restaurant is because they are robots. DrMcninja discovered this when he went looking for McBonald after McBonald attempted to use the Doctors name as part of a marketing campaign for the new McNinja Burger.

In more recent issues he has resurfaced by aiding the Radical Regime through his astronaut nuggets, and later he joins the pursuit of Mcninja after the world learns his name.
