Apperance: cyborg with a shark-like appearance, though it is never specified what his species is. He has silver skin, sharp jagged teeth, has thick, black eyebrows, and yellow triangular eyes that can turn red white pupils when he is enraged. His pupils resemble pointed-ovals, that can widen when very sad (like when he did that after Katie called him "dad, or after realizing and feeling bad about how he told his kids to "stop gawking" when he said that exact line to Toomp). His upper eyelids are dark gray, while his lower eyelids are dark blue, and he bears an X-shaped scar on his forehead. His feet are notably bulky and modelled after jet-powered blasters, each secured by a single black belt. His hands are asymmetrical, with his left arm being larger than his right but also detachable. His fingers have holes on the tips for where he can use them to shoot. His left hand also has a melded-in piece attached on the back of his hand thats somewhat resembles brass knuckles. For clothing, he wears a white shirt beneath a gray jacket featuring horizontal stripes at the hem with a gray patch on the back. His right sleeve has yellow and blue bands encircling it, while the jacket itself is adorned with metal plates, some shaped like turrets, and several belts. The jacket's teeth are gray, jagged with a collar, fitted with bolt-like details. The bottom section consists of matching pants, including a light blue patch on the right leg, a light blue belt on the left leg, and a gray belt. He also wears a knife around his neck in the place of a tie, a pair of goggles resembling unused turrets, armored shoulder pads and leggings, and robotic gloves. Personality: He is shown to be ruthless and reckless to successfully achieve his goals- His expertise in weaponry and mechanics and his very aggressive behavior makes him extremely dangerous, often requiring multiple people to take him down. Mr. WPNZ, in truth, is a bloodthirsty, sociopathic individual. What stands WPNZ out from other villains in the series is his super serious demeanor and how prone he to becoming incredibly violent and short-tempered and really aggressive. He will fight and seriously injure people when he does so, and displays actual enjoyment in bringing pain to his enemies. He is very persistent and also shows to hold grudges against anyone who has wronged him. He is shown to easily lose his temper and burst into rage very easily too, cursing a lot even for the show's standard, also being incredibly serious when compared to most characters in the series. Despite his homicidal personality, he still values loyalty and friendship. He bonds with Toomp and Mr. Puzzles, treating the former with care and respect while offering genuine advice and support to the latter when noticing his stress. This, alongside his friendly attitude towards "Boxhead", shows that he came to view Puzzles as a genuine "friend"
