Richard Horvitz is the voice of Zim in Invader Zim. He is also known voicing as Grey Matter from Ben 10, Billy and his father, Harold from both The Grim Adventures of Billy & Mandy, and Grim & Evil, Daggett Beaver from The Angry Beavers and Lugosi from Bunnicula.


He was born in Los Angeles, California in 1966 and currently lives there. His stage and film credits are too numerous to mention.

He has worked on the Cartoon Network series The Grim Adventures of Billy and Mandy and Grim & Evil, playing Billy and Harold, and got the role of Rodney J. Squirrel in another cancelled series, Squirrel Boy. Richard was also the voice of Grey Matter from Ben 10. He is now the voice of several characters in the Skylanders games, and was the voice of Alpha 5 in Mighty Morphin Power Rangers, Zeo and Turbo. Several years later, in 2002, he was called back by Saban to voice Alpha 7 in the 10th anniversary episode Forever Red; however, he was only given one line at the time due to time constraints with the episode's filming.

He is happily married to playwright/screenwriter Kristen Lazarian, and they have three sons: Jake, Cole, and Wyatt. Along with his wife, Richard wrote Keeper of the Reaper, an episode of The Grim Adventures of Billy and Mandy. He also is the voice of Alpha 4, Alpha 5, and Alpha 7 on Power Rangers.

At InvaderCON III: Final Doom, when asked a three-part question about the Power Rangers Christmas special Alpha's Magical Christmas, Richard replied that he thought it was a great idea and that he enjoyed being a part of it, saying that it was "a smart marketing idea" to not have the Power Rangers appear; when asked if he had fun recording all of the songs he replied that it was very difficult to record songs in a character's voice, and when asked if he was impressed and/or confused with the story of the special he said that when Bob Manahan (the voice for Zordon at the time) and he went into the booth to record they are never told an episode's story outright, but go into the booths and record their lines, which slowly builds pieces of the story.[1]

Invader Zim

Initially, when Richard was considered for the role of Zim, Nickelodeon discouraged the choice, since he was busy voicing Daggett on The Angry Beavers, another show that was airing at the time. As such, he did not voice Zim in the Pilot, and Billy West took the role instead. However, when Angry Beavers got cancelled, he was able to snatch up the part. Richard then recorded his own performance of the Pilot and some of his lines have been intermingled with West's.[2]

At InvaderCON, when asked a question about Zim wanting Gaz as his "love-pig" (based on the various things they have in common with each other like hating the world and Dib), he joked that Zim loves Tak.[3] The show itself, however, never confirmed this, and Jhonen Vasquez himself has said countless times that Zim and Tak will always be enemies.[Citation Needed] A fan also pressed him at a signing to say he loved Dib in Zim's voice, but instead hesitated, then said: "I hate Dib! I am Zim!"
