EXCLUSIVE: The sci-fi adventure has been Disney XD‘s No. 1 series among total viewers and key kid demos this year. Now the channel has ordered a third season of Lab Rats, which follows an ordinary teenager (Tyrel Jackson Williams) who attends high school with his older teen siblings (Spencer Boldman, Kelli Berglund, Billy Unger) — who happen to be super-humans with bionic powers. “The comedic storytelling coupled with the chemistry between our incredibly talented creative team and ensemble cast has created a show that resonates with our Disney XD audience,” said Disney Channels EVP Adam Bonnett. Lab Rats was created by Chris Peterson and Bryan Moore, who exec produce along with Hayes Jackson. Production on Season 3 of the series from It’s A Laugh Productions begins in September in LA for a winter 2014 premiere. Lab Rats got a 26-episode order for Season 2 in November.
