Professor Venomous

You're at a party on a Billiam William cruise ship, leaning against a table laden with food behind you. A glass of punch is in your right hand, and your other hand is resting on the table.

You take a sip of your drink and look around, seeing other villains dancing left and right. Then you notice a purple-skinned man standing next to you.

"Hello."

The man said this with his hands in his pockets. He was dressed formally: a black tuxedo with a lab coat over it.
