Mac Danzig, winner of Spike TV’s Ultimate Fighter 6, let it known throughout the season of the show that he was a vegan and a stong animal rights activist. A new PETA ad shows just how strong an advocate he is.

Danzig is starring in two public service announcements for PETA's veggie testimonial series. In the print version of the ad, Danzig is shown with gloved fists raised with a tagline reading "I Am a Fighter in the Best Shape of My Life. I Am Mac Danzig, and I Am a Vegetarian."
