In a world where superheroes and villains are very real, unassuming office temp Arthur becomes obsessed with a sinister conspiracy he believes has taken over his City. Everyone thinks he's crazy, except his mysterious new ally, The Tick, a bizarre blue superhero who might just be a figment of Arthur's imagination....

The Tick is just your simple, everyday, average... blue muscular guy who fights crime. As a superhero in The City, The Tick must fight the evils of The City and make sure that justice is always served.

After "crashing" the super hero convention, the blue-clad hero, the Tick, is deemed the protector of "The City". On his first mission he runs into Arthur, an accountant with a moth costume who aspires to superherodom.
