Disney XD's Lab Rats Wiki
I'm here because I heard what happened to you guys, and I'm just glad you're okay.
— Perry to Donald, Adam, Bree, Douglas, Chase, and Leo in The Vanishing

Theresa "Terry" Cherry Perry is a major character and the main anti-hero of Lab Rats. She used to be the principal of Mission Creek High School, 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 was not shown in Season 4.

She is portrayed by Maile Flanagan.


Perry was born under Centium City, which was confirmed in the Lab Rats: Elite Force episode Follow the Leader. She grew up in a rivalry with her identical twin sister and got made fun of as a kid at school. Her fellow students made fun of her name; "Is Terry a boys' name? (Chip Switch)." Perry has had several side jobs, including the "Jammer" on the North Pacific Roller Derby Championship Team, a prison guard (though she was also in prison once), and a "flag lady", seen in The Bionic 500. She lives with her eight cats and mother. She loves tormenting kids and is Irish. It is also mentioned that she was a street fighter in Bangkok (You Posted What?!?).


Initially, Terry Perry absolutely loved tormenting the overall student body, showing that she is quite sadistic. She particularly enjoys tormenting Leo, along with Adam, Bree and Chase. She also loves calling people nicknames. Despite her rather tough demeanor, Perry is shown to be rather childish as she quivered in fear when her mother came by and pouted when Adam, Bree and Chase told her to simply stand guard. She also thinks she's very appealing to people, such as when she described herself as "hot rod" calendar girl in (The Bionic 500), and in (Spy Fly), when she tried to apply in beauty pageant, however, when they didn't accept her, she said "but my bikini tells a different story." There are numerous layers to her overall personality as she can be human at times and then resuming her mild sadistic personality. She loves blackmailing "Daddy Big Bucks" by saying that she's going to "spill the beans" about the "3 Bionic Freaks" (But now it's the "4 Bionic Freaks" because Leo got bionics in "You Posted What?!"). But when their secret is exposed she can't blackmail them, so she joined their side. She is also very flirty towards her crushes and calls them nicknames (just like everyone) and follows them around. Besides her bad nature, she did good things to the Davenport family, such as in (Twas the Mission Before Christmas), when she cooked dinner for them since she knew that she ruined their holiday. Even so, she still made them pay for the dinner. In addition, she will help the Lab Rats to an extent, but only if the situation is dangerous enough for her.

Later on, Perry developed a soft side for the Lab Rats, to the point where she felt tormenting them brought her closer to them. When they left Mission Creek, Perry admitted to missing them, because tormenting them was the one thing that meant so much in her life, which led her to completely lose interest in tormenting other students.

In "Space Colony", Perry showed that she has become to love the Lab Rats deeply, despite entertaining the idea of them getting killed. As when Adam, Bree, Chase and Leo were taking on Krane and Gao while trying to rescue the space colonists, Perry could have ditched the Lab Rats and left in Davenport's spaceship, but stayed and waited for them to get on board. And when she thought Adam had died, she was heartbroken and comforted a grieving Bree. And was overjoyed to know he was alive.

  • Skilled Wrestler: Terry Perry is a former Luchador (masked wrestler) and has shown to have retained some (or possibly all) of her skills. She easily proved to be more than a match for Spike, who is already skilled fighter (although more along the lines of a martial artist than a wrestler). She frequently keeps herself in shape, as shown in Space Elevator.
  • Peak Human Durability: She easily shrugged off all of Spike's hits, even when being slammed into a wall. She also shrugged off Krane's electric attack, though this could be partly because she has metal parts in her left side and skull. Despite this, she can still suffer concussions.
    • Tranquilizer Immunity: Perry is mostly immune to neuromuscular-blocking drugs, such that it takes three tranquilizer dart guns to take her down.  
  • Tactical Thinking: In the episode, Unauthorized Mission, she is shown to be a very wise thinker and very cunning. She's able to pass all of Donald Davenport's security without them noticing. She is able to outsmart Donald and became the Head of Security after convincing Donald that he needs a Head of Security and that she's qualified for it. As a former principal and prison guard, it is possible that she is very intelligent in many other ways.
    • Detective Skills: In the episode, Bionic Rebellion, she is shown to be an expert at investigation as she was able to figure out the Sebastian stole explosives from the vault. Perry was also able to predict Sebastian's next move, due to being an ex-criminal herself.
  • Peak Human Strength: Perry has the strength of a Dutch Belted Ox, the grip of a Kodiak Bear, and the kick of a Kangaroo. With this, Perry is strong enough to pry open the hydro-loop door, which was made of Titanium. Apparently, when she dropped a dumbbell on her toe, she shook the entire academy. She also somehow managed to overpower Spike, despite him being stronger than Adam.
  • Acute Scent: Perry has the nasal cavity of a bomb-sniffing dog, due to a nose job.


  • Douglas Davenport: In You Posted What?!?, when she was around Douglas, she got red cheeks forsaking her abilities of being skilled wrestler and not being focused.
  • Mother: In My Little Brother, it's shown that she fears her mother. This is proven when she said, "Sorry, mother. I didn't mean to raise my voice" in a very shy and scared tone.
  • Anger: Her greatest weakness is her anger, which will cause her to lose sight of her defense.  
  • Compulsive Lying: Perry is a compulsive liar, having a tendency to make up things whenever asked. It was her compulsive lying that that caused her to get fired.
