Leo Dooley

**Leo Francis Dooley** (born May 7, 1999) is the main protagonist of *Lab Rats*. He is Tasha Davenport and the notorious spy Ty Johnson's son, Donald Davenport's step-son, Sarah Johnson, Claire and Janice Dooley's nephew, Izzy and Douglas Davenport's step-nephew, Naomi's half-brother, Adam, Bree and Chase's adoptive brother/cousin, Marcus and Daniel's step-cousin, Francis and Rose Dooley's grandson, Dexter and Daphne Davenport's step-grandson, Janelle's ex-boyfriend, and Taylor's boyfriend, one of Logan's best friends, and Lea Dooley's male counterpart.

He is a teenage superhero who was a normal kid until discovering his new bionic siblings who lived in his new step-father's basement. Though he was scared of them at first, the Lab Rats became his siblings and best friends. Showing his new siblings, the real world for the first time, Leo struggles to fit in at school and gain his step-father's approval to become more involved with the team and Davenport Industries. Leo finally proves himself to Donald in a mission that Adam, Bree, and Chase miss and is made the team's Mission Specialist. Unlike his siblings, Leo did not need bionics to become a true hero. He is the normal kid in the family until he has bionics implanted in his arm by his step-uncle, Douglas Davenport, after it was crushed by Taylor as S-1 and given a bionic leg by Donald after it is crushed by a space elevator. He is the third-youngest of the Dooley-Davenport children and the future father of Ava and Talya Dooley and uncle of the Davenport kids, Evie, Chase, Jr., Emma, Liam and Michelle and of Lily and Rachael Krane.

Leo is a member of the **Dooley-Davenport Family**, the **Johnson Family**, the **LTL Trio**, and the **Lab Rats Team**

## Personality

Being a teenager in high school, Leo is still trying to find his place in it and in the world. At the beginning of the series, he was in still in his clumsy phase. However, Leo can be arrogant at times, though not as much as Donald.

He is very close with his family and will do anything to protect them.

In Season 3, Leo had begun maturing, and began inventing things without breaking Donald's things, such as inventing orbs that he invented so they could protect Adam, Bree, and Chase from Douglas and Krane. Though the orbs went haywire, but Donald admitted Leo had a good concept going on.

Leo is also willing to put the past behind himself and his enemies if they show change, as he did with Douglas in "Taken" and Taylor (S-1) in "One of Us." He willingly listened to what Douglas had to say about Victor Krane and agreed to a fresh start with Taylor, eventually becoming friends with them.

Like his uncle and brother, Leo felt overshadowed by his older siblings, similar to how Chase felt when Adam and Bree are praised more than him in "Avalanche" and how Douglas felt with Donald all of his life. This is shown in "Lab Rats: On the Edge," where he expresses hope that his siblings don't see him as just their little brother. After saving Chase and taking charge, Donald realizes Leo is ready and levels him up to mentor, where Chase tells Leo he is proud of his little brother.

## Powers and Abilities

* **Bionic Arm:** After Leo's arm was crushed by a ceiling beam caused by Taylor when she was known as S-1, Douglas Davenport healed it with bionic components after learning his stepnephew would never be able to use his arm again. It have him secret abilities so Leo could have a defense skill.
	+ **Super Strength:** Leo has strength in his arm similar to his stepbrother, Adam Davenport, being able to lift a couch with his one arm and punch a dent in the wall.
	+ **Laser Sphere Generation:** Douglas gave Leo the ability to generate laser spheres in his hand. It is Leo's primary ability, and he uses it to knock out dangerous opponents, such as Victor Krane and Taylor (S-1)
		- **EMP:** Combined with Taylor's abilities, Leo and Taylor can create an EMP generation that can take out anything. The first time they did it blew out the electricity on Bionic Island and when they did it a second time, Leo accidentally caused her to go permanently blind. A third time, they were able to use the EMP ability to take out the safety lock that kept Donald and Leo's entire family locked in their self-driving car.
	+ **Energy Transference:** Douglas unlocked this ability for Leo during the Battle of the Bionic Soldiers. It allows him to absorb energy from another source of power. He can also use it in Battle, as he used it to take out Taylor back when she was only S-1.
* **Super Durability:** Leo bionic arm and leg are more durable than his non-bionic limbs.
* Bionic Leg: Leo was given a bionic one by Donald after his original was crushed by a space elevator.

## Relationships

### Chase Davenport

Chase is Leo's cousin/step-brother. Out of all his siblings, Leo appears to be closer to Chase than he is with Bree and Adam. This is most likely due to the fact that both Leo and Chase are the youngest members of their family and are often teased by their older siblings. They often hang out together and finally formed a deep bond and relationship in "Robot Fight Club" when they win a Robot Throwdown. Leo was also the only one able to snap Chase out of the Triton App by reminding his brother of the good times they had together. Despite their closeness, Leo often teases Chase but not as much as Adam does.

Their relationship was temporarily strained in "Lab Rats: On the Edge," when Leo felt overshadowed by Chase and his siblings. However, the brothers reconciled when Leo saved Chase from falling over the edge, and Chase revealed he couldn't have been any more prouder.

### Adam Davenport

“*Adam is 6 foot 2, a rare combination of incredible strength and nothin' much else.*”
―Leo describing his older brother

Out of all their siblings, Leo and Adam appear to be the least close. They first met in "Crush, Chop and Burn" when Leo accidentally discovered Donald's lab. In the show, Leo will sometimes get annoyed with Adam's stupidity and out of the two of them, Leo appears to be more responsible. Despite this, Adam loves Leo as much as he does his other siblings and will be protective over him, as one of Adam's hidden abilities showed up when he saw Marcus about to kill Leo again. They hang out together, such as "Adam Up." Adam also worried for Leo when his arm got crushed by Taylor and Adam drove the protesters (including Principal Perry) away from Leo with his breath ability. He was proud of his younger brother when he went on his first official mission with them.

Currently, Leo and Adam are running what is left of the Bionic Academy, allowing room for them to grow closer.

### Bree Davenport

“*Bree is my sister, and I have to fix this.*”
―Leo to Douglas
Bree is Leo's older step-sister/step-cousin, and they first met in "Crush, Chop, and Burn," where Leo accidentally stumbled upon her and her brothers. He was the first one to show Bree the real world and how to be a teenage girl. Bree makes it her responsibility as Leo's older sister to see her younger brother following the right path, as she told him to take the blame and tell Perry he cheated off of Bree on her test. Like Adam, Bree can be protective of Leo, Bree was concerned when Leo was trapped in the training room with the rest of the bionic soldiers and was scared when Sebastian ordered them to take him out.

Leo tried everything to restore Bree's chip, even going to Douglas, the man who originally created it, to help them.

### Janice

Janice is the sister of Leo's mother Tasha, therefore his maternal aunt. It is implied the two have a healthy relationship because she helped him perform a dance in front of the girl he liked with her book club.

### Donald Davenport

Donald is Leo's stepfather and has been since 2012. Since Leo's biological father is never mentioned, Leo appears to be close to Donald as his father-figure. Donald tries too hard to bond with Leo, and once blew it with him when Donald revealed to Tasha Leo's secret crush when Leo wanted the secret kept between them.

Leo mainly calls him "Big D" because of his position as head of the Davenport Household. However, Leo doesn't have the best relationship with him, even admitting he's not all that good.

At the time of season 2 Leo and Donald appeared to get along better, as Donald begin trusting him with missions and being a part of the team. He is fairly protective of Leo as much as the lab rats, as he shouted for Douglas to leave his son alone and was relieved to see his son alive when Leo came in the middle of the battle.

### Douglas Davenport

Leo and Douglas used to be bitter enemies until "Taken" when Douglas goes to Leo for help on protecting their family from Krane. After his reformation, Leo and Douglas get along better and despite often tease each other, they do care about each other. Douglas made him a bionic arm after learning he will never be able to use its original arm ever again and apologizes for framing his nephew's own father. Izzy knew Leo was Douglas' first real friend in a long time.

### Daniel Davenport

Daniel is Leo's younger step-cousin. Ever since Douglas introduced Daniel to the Academy, Leo could relate to Daniel a lot, as he shared much of Leo's same experiences of feeling wanted in his family, and was reckless with his bionics much like Leo was when he first received his bionics. Daniel was glad to make Leo and his siblings' acquaintances, mainly because Daniel was glad to have more family members.

Leo and Daniel grew closer, as Leo told his cousin to give Douglas a chance. Daniel eventually became one of Leo's students, and Leo continued to teach him how to properly control his bionics.They are stuck in the past in "Through Time and Space" and have to go all ''Back to the future'' and get their grandparents (Donald and Douglas' parents) back together

### Other Relatives

On the show, Leo's father is never mentioned in the series at all but in the Further Adventures of the Lab Rats, it is known that two are enemies.

According to Bionic Showdown, Leo's step-grandmother, Daphne Davenport, tends to never stop calling her family. Douglas later mentions his and Donald's father, Leo's step-grandfather, Dexter Davenport who Douglas at least 20 bucks from. Leo and Daniel helped them get together.

Additionally Leo has another aunt who is Tasha's other sister and a grandfather is mentioned in Three Minus Bree, where Leo mentions that Eddy may have inadvertently caused his grandparents to break up with each other. However it is unknown if he is referring to Rose and Tasha's father or if he is referring to his stepfather's parents.

### Taylor and Logan

**Main Article:** *LTL Trio*

Taylor and Logan are Leo's best friends (outside of Adam, Bree and Chase) and teammates.
