Leo Francis Dooley (born May 7, 1997) is the main protagonist in Lab Rats. He's portrayed by Tyrel Jackson Williams. ==Leo Francis Dooley's life before is mostly mystery but some information is known. For example, he was a great dancer in Episode 4 so he might of went to dance classes. In his old school he was nicknamed as Leo Doodey. In the episode of, You Posted What?!, Douglas Davenport gives Leo super strength and energy grenades. He is also very short for his age. In the episode of, Speed Trapped, the automatic car voice system said, Child Mode is always engaged for children under the age of 9.He was a great with his bionics. And has good luck every time.


He is very kind, immature, intelligent, and over-protective over his step-siblings. Also a manipulate person as example over his teachers and family. He also says a lot of funny sentences like the Talent Show scene in, Spike's Got Talent.

Leo: Yes! For my next trick, I will leave while I'm ahead.

(Chase goes on the stage)

Principal Perry: What's your talent? Other than having my middle school haircut.

Chase: I am the smartest man to ever live!

(Audience gets bored and throws papers at him)

Principal Perry: You're not in. NEXT!

Chase: Wait, I can do magic!

Leo: Oh no you can't!

(Chase starts moving papers with his mind)

Principal Perry: Wow! That was amazing!

Principal Perry: Dooley, you're out! Little Dutch Boy, you're in!

Chase: Yes!

Leo: Nice job Chase, oh yeah, maybe for your next trick, you can remove this KNIFE, from my back!

==Relationships with other Characters


hello I like your foolishness in the series lab rats

(Status: Step-brother:)Edit

Silly character and a strong boy (Enjoys picking on Chase) and Adam needs more brain cells in order to communicate better and understand things more.


(Status: Step-sister)Edit

She's his step-sister. Even though Leo and Bree are step-siblings, they get along pretty easy. One thing that they both have in common, is that they both have love interests. Bree is more mature though. She is also SUPER FAST and can do stuff fast too and as long hair.


(Status: Step-brother) Chase is Leo's step-brother. In the episode, Mission: Space, he was amazed that Chase unlocked his hidden ability: molecular telekinesis. He is the smartest and is always the mission leader because he's the most trustful of the 4 siblings and he enjoys picking on Adam and Leo. He is also very good at coding and hacking.


(Status: Step-father)Edit

Donald is his step-father. In some episodes, Donald and Leo work together to fix the problems but they sometimes cause trouble like the virus that Leo accidently downloaded in the episode of, Night of the Living Virus.


(Status: Biological Mother)Edit

Tasha is his mother. She is very caring for Leo and she is a news reporter. She always had a strong hate on Donald Davenport's computer friend, Eddy.


(Status: Smart Home Computer System)Edit

Eddy is a very funny computer who always plays jokes on people and he also likes to pick on Tasha. He's been deactivated many times because of his rudeness.

Principal PerryEdit

(Status: Bossy Principal)Edit

She's an idiot mother fucker

Principal Perry is the principal of Mission Creek High School. She also likes cats and she had a weird personality. She likes golfing and she thinks that Leo is annoying for some reason.

Powers and AbilitiesEdit

  • Enhanced reflexes: At first, he had no bionic abilities. Then, his arm got crushed in You Posted What?! then Douglas gave his arm bionics to save it. Even so, Leo has reflexes that are far superior than the average person, which allows him to easily dodge and/or deflect laser bolts (even from weapons geared to destroy super humans and controlled by a supercomputer), and redirect those laser bolts to strike even small targets with pinpoint accuracy (as he demonstrated in Night of the living virus and The Rats Strike Back. He says that he developed those reflexes because of his life-long love of playing video games.Then in Space Elevator his leg is crushed and replaced by a bionic leg
  • Intelligence:While not in the same class as Chase or Mr. Davenport, Leo is a very intelligent kid. With all of the advanced skills he's developing as a result of his new life, it's possible that Leo could become even more intelligent (in Back From the Future, the older, future Leo is implied to be the future Mr. Davenport's assistant).
  • Tactical thinking:Leo has a gift for sizing up a situation and coming up with solutions, even while under extreme pressure. Also,because of growing up less sheltered than the other kids or even Mr. Davenport, Leo's instincts about people are far sharper, allowing him to size up people very quickly. (Leo immediately recognized Marcus as a threat, and Marcus, in turn, considered him a serious enough threat that he tried to eliminate him (in Speed Trapped) - and threatened him with exposing the entire family to the world when he couldn't eliminate him outright.)
  • Bravery: Despite his childish attitudes, Leo has a strong sense of courage. In "Back From The Future," he didn't hesitate to push all three siblings to safety when they were nearly killed by falling debris (almost being killed himself), and in "Missin' the Mission," he went into a dangerous situation to help Mr. Davenport stop a toxic gas leak (while Adam, Bree and Chase were being kept in detention at Mission Creek High School by Principal Perry). Leo also stood up to Marcus, even after being threatened with Marcus' heat vision.
  • Computer knowledge:In "Night of the Living Virus," it is shown that that he seems to know how to hack into computers.
  • Electrical Generation (Alternate Universe): In "Parallel Universe," Leo gains this in the world where he is bionic. He harnesses the static electricity from his surroundings and utilize it to create lightning bolts.
  • Super Speed (Alternate Universe): Leo uses this ability three times in "Parallel Universe," all in an effort to either escape or to defend Mr.Davenport and himself.
  • Super Intelligence (Alternate Universe):Presumably the same as Chase.
  •  Super Strength: (In You Posted What!!!!!): Leo gets this ability after reciving bionics from Douglas Davenport.  
  • Geo Leaping (Alternate Universe): In "Parallel Universe," Mr. Davenport reveals to Leo one of his newly uploaded abilities as they attempted to escape. Leo molecularly transports himself (and whoever he touches) from one place to another by thinking about his destination.


  • Physical Inferiority: Because he is so small and tiny, Leo is  physically weaker than most people
  • Normal human: As he is not bionic and lacks the durability and abilities that comes with being bionic, he is constantly at a disadvantage in many if not all situations.
  • Self-defense incapability: Unlike AdamBree, Chase, and Mr. Davenport, Leo is not taught in martials arts and does not know how to fight. He has to rely on technology or other things to defend himself. Also he is very little which is another problem.
  • Bully victim:  Because of his size and how unpopular he is, he is a very easily targeted bully victim.
  • Inexperience: Leo's inexperience on missions makes him very vulnerable to danger.
  • Arrogance: Leo can be quite arrogant at times, expecially if things start to go his way, more often than not he will blow his good luck, by being arrogant and pushing it to far.
  • Creating his own problems: Leo has a habit of creating his own problems, although this is normally accidental and usually stems from him not understanding the implications of what he is doing.
