Rigby is a 23 year-old raccoon. He is one of the protagonist (other being Mordecai) (sometimes the deuteragonist, or even antagonist) of the series. He debuted in the original Pilot episode (where he was the second to speak on the show) working as a groundskeeper of the park. He is voiced by William Salyers. Although Rigby is 23 years old, just like his best friend Mordecai he acts as if he is a wild teenager most of the time.
