Leo Dooley

**Leo Dooley** is the main protagonist of *Lab Rats* and one of the main characters of *The Lab Rats Chronicles*. He was the only son and eldest child of Tasha Davenport, the older half-brother of Naomi Davenport, the stepson and second-youngest child of Donald Davenport, the 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, Douglas installs bionic implants in Leo's arm to save it after it was crushed by a ceiling beam caused by Taylor. Donald put bionics in Leo's leg after it was crushed by a space elevator while saving his step-father, this making Leo half-Bionic compared to his siblings.

## Canon History

Leo was the only son and eldest child of Tasha Davenport, the older half-brother of Naomi Davenport, the stepson and second-youngest child of Donald Davenport, the 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, Douglas installs bionic implants in Leo's arm to save it after it was crushed by a ceiling beam caused by Taylor. Donald put bionics in Leo's leg after it was crushed by a space elevator while saving his step-father, this making Leo half-Bionic compared to his siblings.

## 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.

## Powers, Abilities and Weaknesses

### Bionic Powers

**Semi-Bionic Physiology**/**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 through walls.
* **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 any electronic device of a high power. The first time they did it blew out the electricity on Bionic Island and when they did it a second time, Leo accidentally blinded Taylor and the third time, they successfully disabled the safety lock that was installed on the top of Donald's 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.

### Weaknesses

#### Glitches

* **Super Strength Unawareness:** Though his super strength cannot glitch, Leo sometimes remains unaware that he is using his bionic strength or has it, 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).

## Relationships

### Adam Davenport

Adam is Leo's adoptive step-brother and 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 care 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

Bree is Leo's adoptive step-sister and 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

Chase is Leo's adoptive step-brother and step-cousin and due to their close age, they 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

> *Main Article: Danleo*

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

### Donald Davenport

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

Douglas Davenport is Leo's step-uncle since Donald is brothers with Douglas. 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 made an assumption 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 has to stop himself from taking Douglas out five times a day,

### Tasha Davenport

Tasha is Leo's 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

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 Daveport's limo, where Taylor told Leo that blinding her was only an accident

## Trivia

* Despite Donald telling Leo would never be able to handle Bionics, he still handles it well when he first got them. He was just bad at aiming.
* Leo was the normal kid in the family until he got his Bionics in "You Posted What?!" Douglas taught him how to use them properly. However, he didn't put into the fact that Leo could glitch because Bionics are only in his arm and not in his central nervous system.
* He finally gets to go on a mission with his family and his mission suit in "Rise of the Secret Soldiers."
* Leo becomes a mentor in "Lab Rats: On the Edge."
* Leo does not need a full capsule, just one for his leg and arm.
* He was immune to the Doomsday device that Victor Krane installed in all the kids because Leo was never put under the Triton App. However, he was put under the Triton App in "Space Colony."
* Leo never got to battle Marcus because both Daniel and Douglas defeated him.
