Marvin the Martian

This little man from Mars with a pet dog has the megalomaniacal ambition to conquer the world and is possibly trying to compensate for his stature, indicating that he suffers from Napoleon Complex. In the process, he can, without remorse, disintegrate anyone who comes in his way, with a calmness that only shows his Antisocial Personality Disorder, further explaining his disregard for safety. Strangely, he believes he can single handedly take over the entire earth, an impossible task even with the most advanced technology at his disposal, clearly stating that he has Delusional Disorder.
