Leo Dooley

**Leo Francis Dooley** is the second-youngest of the five bionic teenagers and the main protagonist of the Disney XD 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 in an attempt to save Donald.

As of the Fouth Season, Leo is the second-youngest of the bionic kids, after the discovery of his younger step-cousin, Daniel.

## Powers

* **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 andTaylor (S-1)
		- **EMP Generation:** 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 and allowed him to absorb an enemy's attack and project it right back at the opponent,as he did with Taylor when she tried using Pyrokinesis against him Leo absorbed the fire and directed it back at her, shooting her into the sky.
* **Bionic Leg:** After getting wounded by the Space Elevator, Donald had to replace Leo's leg with a bionic one. It is shown to be strong enough to break a cage he and his siblings were entrapped in and of course, is stronger than his Bionic arm, which he could only create a small dent with. He can also kick things hire.
* **Super Durability:** Leo bionic arm and leg are more durable than his non-bionic limbs. It is shown that when Douglas gave Leo Bionics, his arm was completely healed, not even leaving a scratch.

### Skills

* **Leadership/Expert Battle Tactician:** Despite being irresponsible at first, throughout the years, Leo became a capable leader. Chase tells Tasha that Leo knows how to remain calm in dangerous situations and take control whenever they are on missions. This is shown in the episode Forbidden Hero, where Leo directed Adam on rescuing his mother. In Lab Rats: On the Edge, Leo mananged to lead Logan and Taylor in rescuing his family. He directed Taylor with creating their EMP Generation ability and then use Logan's Energy Manipulation ability to direct the EMP to a device that was keeping Leo's family locked in the self-driving limo. Because of his leadership, Donald promoted Leo to mentor and Chase acknowledged that Leo was meant to be a hero.
* **Martial Arts:** It is shown that Leo can use martial arts like the Lab Rats, though it seems he can only use martial arts when he was bionic. However, in Taken he used it to try to take down Douglas, who points out how bad Leo is at it. However, he improved because Donald trained him.
* **Skilled Fire-Staff Fighter:** In Alien Gladiators, he is seen beating many competitors in the competition even the most skilled ones. He is a formidable fire-staff warrior and even defeated Donald Davenport, who is very skilled in martial arts, weaponry, and fire-staff, itself.

## Glitching

* **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 as he was excited to learn he is bionic). Panicking causes Leo's laser Sphere to go off and accidentally caused a fire that nearly burned Janelle alive. When he was irritated by a fly, Leo tried waving it away but instead, set off a laser sphere that destroyed the couch.

## Property/Equipment

* **Security Orbs:** In the episode "Scramble the Orbs," Leo created them to protect his siblings from Victor Krane and his step-uncle and their creator, Douglas Davenport. However, the security orbs malfunctioned, as they were unable to tell the difference between a friendly threat and a real threat. They eventually destroyed themselves; despite it being a failure, Donald thought they had potential.
* **Medical Diagnosis Capsule:** Leo created a medical capsule that would diagnose people's illnesses and the data would show up on his computer. It was based on Eddie's smart home system. ENded in failure when Leo accidentally transferred Eddy into the pill and it let take control of his mother's body
* **Exoskeleton:** Leo once went in his step-father's Exoskeleton to demonstrate it but Chase messed with it out of jealousy that Donald was paying more attention to Leo than him.  He later used it when storming into Douglas' lair.
* **Mission Suit:** Leo got one in "Rise of the Secret Soldiers" arc. Leo's is different than Adam, Bree and Chase's in terms of style and isn't as skin tight as theirs. It is able to withstand any harshness of climate or temperature.
* **Arm Capsule:** Douglas made an arm capsule for Leo so he could recalibrate his Bionics to his nervous system that he usually wears at night.
* **Firestaff:**Leo owned a firstaff that was just a staff that glowed, which he used during the Alien Gladiator competition in combat against Perry and Donald.
* **SmartPhone:** Leo uses his cell phone to make calls or texting with other people. He used it to contact Donald about Douglas (Taken) and answered a call from Spin, who was asking for Leo's help after he and Bob went on a mission, alone and got trapped in quicksand with Bob.

## Relationships

### Adam Davenport

**(Adoptive Older Brother/Step-Cousin)**

They have a close brotherly relationship and are always there for each other. They do argue and insult each other sometimes, but in the end, they'll be there for each other, no matter what. In Bionic Showdown, Adam discovers his hidden ability when Marcus was about to kill Leo. These two cares deeply about each other and will always help each other out, in any way they can. In You Posted What?!?, Adam was concerned when Leo was hurt. They seemed to have the least plots out of the whole family.

### Bree Davenport

**(Adoptive Older Sister/Step-Cousin)**

They insult each other from time to time, and they tease each other. Bree puts herself in a position as Leo's older sister, and makes him pay the consequences to his mistakes. (Spy Fly) She claims that she wants him to follow his responsibilities as she does with herself. They're always there for each other and care deeply about each other. In Which Father Knows Best? Leo was deeply concerned for Bree and even went to Douglas, (ignoring Donald's rule) to make him fix it. It has been seen in several episodes Bree has helped Leo in most problems. (Smart and Smarter, Not So Smart Phone and Spike Fright)

### Chase Davenport

**(Adoptive Older Brother/Step-Cousin)**

Due to their close age, Chase and Leo have a close relationship, sometimes closer than Chase's relationship with Adam, and are always there for each other. Together they have become very close, seen in Sink or Swim when Leo was the only one able to convince Chase to overcome the Triton App that was controlling him. They work together on some things, but can grow jealous/competitive with each other too. They insult each other a lot and bicker too. But when the time is right, they will help each other out in any way they can. In Bionic Houseparty, Chase was prepared to fight the bionic soldiers because he thought they were going to hurt Leo. In "Lab Rats: On the Edge," Leo saved Chase's life and they hugged twice.

### Daniel Davenport

**(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 eventually became one of Leo's students, and Leo continued to teach him how to properly control his bionics.

### Donald Davenport

**(Step-Father)**

Donald Davenport is Leo's stepfather, who he mainly calls "Big D" because of his position. However, at times, Leo does not have the best relationship with Donald, mostly because Donald tries too hard to bond with Leo. Leo is Donald's lab assistant, often strategizes missions for the Lab Rats. Leo also saved Donald's life in Bionic Houseparty. Leo saved his life by using his energy transference ability.

Despite their somewhat strained relationship, Donald cares for Leo deeply, and considers him his own son.

### Douglas Davenport

**(Step-Uncle, Former Enemy, and Friend)**

At first, Leo was considered a threat to Douglas due to his constant meddling in his plans, and ordered Marcus to eliminate him. Douglas is also the creator of Leo's bionic arm. Leo convinced Douglas to help Bree fix her chip in "Which Father Knows Best?". Together, they assumed that Krane was the girl in You Posted What?!? Leo and Douglas have bonded more over the course of "You Posted What?!?". Douglas helped him become bionic and heal his arm in You Posted What. Douglas also lives with Leo and with the others of The Davenport Household since Donald has allowed Douglas to stay at The Davenport Household until they went to Davenport Bionic Academy. Douglas served as Leo's mentor and teaches him to control his bionics until he became a student at the Davenport Bionic Academy. He makes Leo an arm capsule in Under Siege. Just as with Donald, Leo sometimes disobeys Douglas, which often leads to disaster. Leo even says he must stop himself from taking Douglas out five times a day,

### Marcus Davenport

**(Step-Cousin and Enemy)**

Leo has been enemies with Marcus ever since "Concert in a Can," and failed in convincing his siblings Marcus was not their friend.

In "The Vanishing," Leo was shocked to see that Marcus was alive again and it is revealed Marcus still hates Leo, but seems to hate Douglas more because he left him for dead.

### Tasha Davenport

**(Mother)**

She is very protective over all of him and doesn't like Leo playing video games or watching a lot of TV. She also doesn't like the four plus Donald spending time in the lab. In You Posted What?!?, she finds out that Leo has bionics, and wasn't happy about it. But she is still loving and caring. Tasha cares about Leo, as she didn't want him to go on any missions in Forbidden Hero because she didn't want him to get hurt.

### Taylor

**(Former Enemies, Close Friends)**

Taylor and Leo used to be mortal enemies, and she tried to kill him at least twice and she was the main reason that Leo's arm was permanently damaged and why Douglas had to fix it with bionics. He later battled her in "Rise of the Secret Soldiers," where Leo managed to finally overpower her. However, because she was under the Triton App, Taylor did not recall Leo and met him again in "One of Us," where Leo knocked her out because he thought she was a threat to his friends. However, the two decided to forget everything that had happened in the past and finally, they became friends.

The two became extremely close, afterwards, and discovered a new ability. By joining their hands, they could make a laser sphere so powerful it could knock out all the lights in the Academy. However, this new power caused Leo to accidentally disable Taylor and make her go permanently blind. Despite it being an accident, Leo quit the Bionic Academy and was haunted by what he had done to Taylor. However, Taylor did not blame Leo because it was just an accident. She later called Leo when his family was in danger, as they were trapped in a self-driving car and together, the two managed to save Leo's family by disabling the safety lock device on Davenport's limo, where Taylor told Leo that blinding her was only an accident.
