The Prowler
Hobie Brown was a bright kid going nowhere. Angry after being fired from his window washing job, Hobie decided to use the safety equipment he developed for window washing to become a burglar. Then, as Hobie, he could return the stolen items and become a hero. Creating a costume, Hobie went out as the Prowler.
But during his first robbery, the Prowler encountered Spider-Man, who easily defeated him. Spidey convinced Hobie being a villain was a bad idea, and Hobie took it to heart. Over the years, Hobie has helped Spider-Man on occasion, and uses the Prowler identity to occasionally fight crime and work as a mercenary.
