Theresa (Terry) Cherry Perry, formerly called Principal Perry before her retirement, was the principal of Mission Creek High School in Lab Rats, but is now in the position of Head of Security at the Davenport Bionic Academy. She has been shown to treat her students very poorly, especially Adam, Bree, Chase and Leo. She also blackmailed Donald after she found out about the Lab Rats bionic secret, though lost her leverage after their secret got out. It is unknown who became principal at Mission Creek High School after her retirement, since the school will not be shown in Season 4.
