Richard Steven Horvitz is a noted voice actor who portrayed Orthopox-13 and Orthopox-14 in the three official installments of the series. He also voiced the suburban crazy in the first game, but did NOT voice The Freak, as many think he did.

He is one of America's most cherished voice actors. He is more famously known for voicing Daggett on The Angry Beavers and Zim from Invader Zim, as well as Grey Matter and Sublimino in Ben 10.

He is presently living in his home in the state of California with his wife, playwright and screenwriter Kristen Lazarian, and their three young sons. The couple's oldest of their three sons, Jake Elliot Horvitz, was born April 11, 1998, an event proudly mentioned in one of his shows, The Angry Beavers. He and his wife also wrote "Keeper of the Reaper", an episode of The Grim Adventures of Billy and Mandy. He also voices Alpha 5 and Alpha 7 on Power Rangers.
