**Leo Francis Dooley** is the protagonist of Disney XD's 2012-2016 comedy television series *Lab Rats*. He was the only son and eldest child of Tasha Davenport, the older half-brother of Naomi Davenport, the step-son and second-youngest child of Donald Davenport, the younger step-brother/cousin of Adam, Bree, and Chase Davenport, the step-cousin of Daniel and Marcus Davenport  and step-nephew of Douglas Davenport. Loyal, caring and intelligent, Leo is initially an outcast until he meets his step-siblings, Adam, Bree and Chase and grows up. His stepfather, Donald had a lack of trust for Leo due to his tendency to accidentally destroy things, but has started to change his opinion, as he made Leo the team's "Mission Specialist."

Midway to Season 3, Leo becomes bionic after Douglas installs them to save his arm after it was crushed by a ceiling beam caused by Taylor when she blasted it on top of him and Donald put bionics in Leo's leg after it was crushed by a space elevator while saving his step-father.

## Background

### 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.

## Pairings

In fanfiction, Leo is often paired up with Janelle and their ship is called Janeleo. However, some people will pair Leo up with Taylor because of their support for each other.

## Trivia

* Leo was the shortest member of tFamily==he family, the only normal kid and the youngest (younger than even Chase).
	+ He is now the second-tallest, a bionic teenager since the Season 3 Episode, "You Posted What?" and second-youngest since the discovery of his cousin, Daniel ("And Then There Were Four").
* In the beginning of the series, Leo was thirteen years old.
	+ He turned fourteen in "Bionic Birthday Fail"
	+ He is sixteen by season 3. (Three Minus Bree) and the beginning of season 4 ("Under Siege").
	+ He is (presumably) seventeen by the series finale.
* He was Tasha's only biological child until the birth of her daughter and Leo's sister Naomi. (*Lab Rats: Elite Force*)
* Leo shares some similarities with his brother, Chase:
	+ They are the youngest members of the four main siblings.
	+ They are often teased by Adam and Bree, however, they both get along better with Bree than they do with Adam, who also teases them about their height.
	+ At one point, they also snuck Douglas into Davenport's lab. (however, Chase lured him there and Leo brought him to the lab to fix Bree's chip.
	+ Anti-social and both mocked for their intelligence. (Leo mentioned how hard it is being the smart kid in school)
	+ They often feel overshadowed by their older siblings (Chase gets hurt by the lack of respect his team has for his intelligence, and Leo feels inferior to Adam, Bree, and Chase because they are all bionic humans, and later, because they doubt he has it in then to be more than being the youngest)
	+ They also get annoyed by Davenport's big ego, because whenever Donald tries to improve something, he always lets his big ego get in the middle while he tries improving his younger sons' lives.
	+ Leo also shares some similarities with his cousin, Daniel:
		- They lived their whole lives without bionics.
		- Excited but feeling lost when in their family, the Davenports.
		- They get reckless with their bionics when they first got them.
		- They later became mentor and student.
* Leo went on his first mission in "Rise of the Secret Soldiers" and got his first mission suit in the same episode of the same name.
* According to Donald, he cannot handle high fiber cereal.
* Douglas implies he left a pen in Leo's bionic arm.
* On Adam's website, it says he's the 8 year old mascot called Leo Clooney (Rise of the Secret Soldiers).
* According to Douglas Donald killed most (if not all) of Leo's pets.
* He was the only main character that wasn't originally a mentor at The Davenport Bionic Academy, he was a student. (First Day of Bionic Academy). He did eventually become one in "Lab Rats: On the Edge."
* Leo's voice deepened in Season 3 due to Tyrel Jackson Williams going through puberty in between production of Season 2 and 3.
* Season 3 was about Leo becoming bionic. The episode "Parallel Universe" foreshadows him becoming bionic (an episode in Season 2) and the beginning where Perry tells the students, "Get to class before they shoot missiles from [Bree, Adam and Chase's] fingers]" in "You Posted What?"foreshadows Leo being able to shoot laser spheres from his fingers.
