Dr. Wessel is an anthromorphic male Weasel and the main antagonist of Peter Pika. He's a sinister weasel scientist who attempted to take over the world using the energy of nature. He is also the final boss of the game.
Wessel Vilne was born in an unknown city to two rich parents who weren't nurturing in any sense. Wessel found solace in controversial animal science, and was shamed by his parents and cut off. He began to work on a plot to take over the world, but knew that he had to start somewhere isolated with no threats. He thought that Massive Mountain would be just that place. However, Wessel was defeated by a resistance and shot out into space, where he remains, swearing revenge as he floats outward.
Wessel is overconfident, sinister, and scheming. He has little morals or qualms with the nature of his experiments, and simply wishes to conquer the world. However, it is hinted that that is not what he wants inside, but rather to be accepted and loved.
Wessel is a towering Weasel who has large bushy whiskers an wears a classic lab coat at all times. He also wears goggles on his head that are a transparent dark green.
As far as physical abilities, Wessel is incredibly weak and not a great athlete, but can run fast. His main strength is his high intelligence and his ability to operate robots who can attack in ways he cannot.
- Wessel is arguably the only main character who is not an obscure animal. This is because Weasels pray on Pikas, which is why a weasel was chosen(in additon to the stereotype of the weasel being sinister and scheming).
