The mouse dictator is the main antagonist in Ninja Cat and Mutt Man. Around the beginning of the first episode, he became radioactive, along with 49 other mice, and got an eyepatch as well as a longer nose, which has an edge to it.
The mouse dictator happens to be clever, as he knows what Ninja Cat's weaknesses are, and used this information to make a trap, involving mutant fish(Trout, to be specific). However, he doesn't know Mutt Man's strengths, as Mutt Man has the ability to move without an outside force, even in time snaps.
The mouse dictator also happens to be the most ruthless of the mouse army, and the mouse army is pretty evil, making the dictator demon-like.
