Nemis the Evil Twin

How can Amos have an evil twin? He’s already evil!

This was spawned in my Psychology class. My teacher has lousy short-hand. She was writing the word “hemisphere” abbreviated “hemis” and the “h” was too short. So my friend says, “Nemis? Sounds like if Amos had an evil twin.” Or something along those lines.
So Amos’ evil twin was born. The only difference is Nemis has a top hat, monocle, mustache and goatee (though it’s hard to see cuz of the pose).
