Dee Bradley Baker
Dee Bradley Baker (born August 31, 1962) is an American voice actor, known for roles such as Klaus on American Dad!, all the clone troopers including Captain Rex and Commander Cody in various Star Wars cartoons and games, and a vast array of characters and Omnitrix aliens in the Ben 10 franchise. He has also worked in game shows, voicing of Olmec the stone head from Nickelodeon's Legends of the Hidden Temple, and the announcer/sidekick on the Family Channel and PAX TV runs of Shop 'Til You Drop.
Much like Frank Welker, Baker is known for his ability to "voice" non-talking animal characters, such as all the animals in Avatar: The Last Airbender and The Legend of Korra, Waddles the pig from Gravity Falls, Perry the Platypus from Phineas and Ferb, and Lion and the Gem Monsters from Steven Universe.
