Leo Dooley

* Season 4
* Season 3
* Season 2
* Season 1

**Leo Dooley** is the overall main protagonist of the Disney XD 2012-2016 comedy series *Lab Rats*. He first meets his bionic siblings when he accidentally stumbles upon his new step-father's lab and becomes their best friend. Leo used to be irresponsible and reckless until he went on a small mission with Donald and proved his worth, becoming the team's Mission Specialist and learned to be a true bionic hero. Despite sometimes being destructive, Leo is very brave and will protect his family from anything, proving he does not always need bionics to be a hero.

Leo used to be the normal kid in the family before Douglas Davenport healed Leo's arm with bionics after a freak accident and gave him an ability called Laser Sphere Generation, along with Super strength. In Season 3, Douglas gives Leo the ability of Energy Transference. In Season 4, Leo and Taylor discover a new ability called EMP Generation, strong enough to take out an electrical force.

Leo is the son of Tasha, the step-son of Donald, older half-brother of Naomi and adoptive younger brother/step-cousin of Adam, Bree, and Chase, the grandson of Rose, the nephew of Janice, the step-nephew of Douglas and the step-cousin of Marcus and step-cousin/mentor of Daniel

He is portrayed by Tyrel Jackson Williams.

## 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 his stepfather, Donald.He is very close with his family and will do anything to protect them, as he went the distance to save the Lab Rats from dying in the future and his willingness to prove that Marcus and his father were evil and up to something. He could also be a rebellious teenager like he's mother Tasha was when she was younger and often disobeying his father Donald or his uncle Douglas.

In Season 3, Leo had begun maturing, and 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. It is shown at this point, Leo was 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 both them.

Despite not having super intelligence, Leo was a smart teenager and was mentioned being the smart kid in school in the episode's premiere, mentioning it's not easy for him to Chase and the other Lab Rats. He is also quite intelligent, shown that he never liked Marcus even before it was revealed that Marcus was evil. Leo could also come up with plans for the missions, eventually becoming the team's strategic mission specialist. Like his brother Chase, Leo will sometimes remind people of the bigger picture, shown at least twice. The first time he reminded his siblings that they had to save Donald during the jet wing incident because he did the stupid stunt to give them the Lab back, causing Bree to realize their brother was right. Another time happened in "Which Father Knows Best?" where Leo told Douglas to get past his rivalry with his brother after Leo told him Donald couldn't fix Bree's chip when she broke it because Bree was more important. Additionally, Leo scolded his siblings for causing a blackout and fighting in "Rise of the Secret Soldiers." He also easily deduced that Douglas was behind cyberhacking Donald back when he was evil. Characters such as Douglas has said that Leo is a smart kid ever since the Marcus incident.

Ever since his mother married Donald, Leo remained supportive of her decision. After meeting his siblings, he wanted to become bionic like them, dropping hints to Donald. However, Douglas later gave Leo bionics to save his arm. The boy was excited but reckless with his bionics, something that caused Leo to connect Daniel with. 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. He also expressed hope to Bree and Chase that he would see his brother and sister again.

## Bionic 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. It is more powerful than his bionic arm, being able to cut through the metal cage he, his siblings and the students were trapped in.

## Weaknesses

### Leo's Glitches

* **Super Strength Unawareness:** Though his super strength cannot glitch, Leo sometimes remains unaware that he is using his bionic strength, lifting one of the couches in his living room when he was looking for his smart phone.
* **Bionic Sleepwalking:** Because Leo's arm was not calibrated properly into his nervous system without a capsule, it caused Leo to sleep walk while using his laser sphere ability. However, Douglas gave Leo an arm capsule to stop this from happening.
* **Uncontrollable Laser spheres:** Sometimes, Leo cannot have control of his laser spheres, as they set off uncontrollably when he is sleepwalking. They usually activate uncontrollably when Leo is excited (as he nearly set Douglas' hair on fire), panicking nearly burned Janelle alive, or irritated (by a fly, Leo's laser sphere blasted).

## 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.
