### Fate

Continues to overlook the Davenport Bionic Academy

**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 the world who is sarcastic, caring, but also somewhat insecure. At the beginning of the series, he was in still in his clumsy phase but he formed a quick bond with Adam, Bree, and Chase and despite being scared of them at first, he claimed them to be his best friends. However, he considered thm his own siblings, calling Adam and Chase his brothers and Bree his sister In "Leo's Jam." In turn, the trio have come to see Leo as their younger brother and closest friends. Being young, Leo can be arrogant at times, though not as much as Donald.Leo did this by sometimes using Bree and Adam's bionics to his advantage and trying to one-up Chase. He is very close with his family and will do anything to protect them. This is proven when he tried desperately to prove to his family that Marcus was evil and that he and Douglas were trying to capture Adam, Bree and Chase. Despite teasing each other, Leo always helps his siblings and step-father whenever they are in need, as he went to face Marcus and Douglas to save them when the villainous duo captured them.

In Season 2, Leo began maturing but wanted to become part of the team; however, Donald pushed him aside because he was not bionic. However, after Leo stepped up on a mission that the other Lab Rats missed, Donald realized how responsible Leo was getting and made him the team's mission specialist. By this season, Leo and Chase began having a stronger relationship.

In Season 3, Leo had come a far way from the boy at the beginning of the series, being able to take care of himself, especially after he got bionics. He 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, Donald admitted Leo had a good concept going on. By the latter half of the series, 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. When Douglas first gave Leo his bionics, he was initially shocked, but this immediately melted over as he began using them afterwards.Before long, Leo began misusing them and had very limited training, at least until he was under Douglas' guidance. He fought bravely in the Bionic War against S-1, but he didn't continue fighting because he was busy attending to Donald when he was incapacitated.

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 as he, the rest of the team and the Bionic Soldiers warmly welcomed Leo back. He was also able to connect with his cousin, Daniel because of their commonalities.

### 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.

### Physical Appearance

Leo is a teenage boy who is seen at the ages of thirteen and sixteen, with dark skin, dark brown eyes and curly black hair. Initially, he is fairly short, reaching up to Chase's shoulder, but overtime, he grew taller than Bree, and was nearly Chase's height. However, by season 4, Leo was the taller than Chase, becoming the second-tallest of the Lab Rats, reaching past Adam's shoulder.

Throughout the series, Leo's wardrobe changes. In Season One and Two, Leo wore colored shirts with pictures on it, but this more or less disappeared as it went on. Most notably in the second season, he wore long-sleeved shirts with short-sleeves over them. The only episodes he has not worn long sleeve T shirts is in Crush, Chop and Burn, and No Going Back, where he wore just a T-shirt instead. However, from Season 3 onwards, Leo mostly wore hoodies, long-sleeved shirts, and mostly shirts with button-up sweater with his sleeves rolled up. In "Rise of the Secret Soldiers," Leo gets a mission suit that is slightly different than Adam, Bree's and Chase's. Instead, he wears a black leather jacket that also has a hood. However, his right arm sleeve is red; Leo also has black pants with black pads on his knees and black combat boots.

	+ 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.
