The blue Gadgetini, the more intelligent of the two.
The main villain in the series and leader of the evil organization known as M.A.D. He speaks in a deep, menacing, gravelly voice and his face and the majority of his body are never shown throughout the series; only his arms and gloved hands are visible. He is usually at a computer terminal where he monitors his various schemes. Even though he’s aware of Gadget’s stupidity, he believes the Inspector to be his greatest nemesis, never fully realizing that it is actually Penny and Brain who foil his plots in each episode (although he or his M.A.D. agents have captured Penny and sometimes Brain a number of times). His name is Dr. Gang in the French version.
