The Chainsaw Vigilante was originally based near Deertown and Hobleville. Here, he defeated the Civic-Minded Five. He attempted and failed to defeat the Tick. Haunted by this defeat, he began to hunt the Tick and moved his base of operations to the City.
It is unknown why he hates superheroes. However, it was implied he was the son of socialist villain the Man with Seven Hearts. The Man was forced to flee America when the legendary superhero the Sultan exposed his communist brainwashing. If CV is his son, this might be what inspired his hatred of superheroes.
The Chainsaw Vigilante uses a Sears and Roebuck brand chainsaw as his weapon of choice. He wears a crude homemade mask to hide his identity.
