Professor Venomous

Professor Venomous is tall with a slender body and lilac skin (due to an experiment trying to get his powers back). He has black, spiky, slicked-back hair, a thin mouth with thin eyebrows, and dark purple eyelids. His nose is pointed and has stubble along his chin and lower jaw. His attire consists of a white coat with matching boots, a navy blue turtleneck underneath his coat, and black pants. Professor Venomous has a deep husky voice and is taller than most people.

Professor Venomous is typically calm and indifferent in his interactions. However, he has a more vicious side beneath his cool exterior that he expresses during interactions such as fights with heroes. He has also repeatedly expressed his admiration towards Boxman's dedication to destroying the plaza. He has been shown to have a softer side to his personality and treats his minion Fink with great care and kindness, even going as far as to act as a parental figure to the young villain.
