## Character Information

### Created By

Chris Peterson and Bryan Moore

**Leo Francis Dooley** is one of the two protagonist of Disney XD's 2012-2016 comedy television series *Lab Rats* (alongside his step-brother Chase 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."

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

Of his older siblings, Leo is the youngest of the Lab Rats and the third-youngest of the Dooley-Davenport children of his siblings and cousins.

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.

## Role in the Series

### Season 1

Leo makes his first official appearance in the *Lab Rats* premiere “Crush, Chop And Burn” where he and his mother Tasha move in with her new husband, the millionaire and inventor, Donald Davenport. Inside, Leo meets Eddy his step-father’s home computer and accidentally discovered three bionic siblings living in his basement: Adam, Bree, and Chase while trying to find his way around the house. At first, Leo is scared of the siblings, as his screams alert his parents. Tasha is additionally shocked to discover what her son stumbled upon until Donald introduces his wife and stepson to the siblings and tells them their purpose: to use their bionic abilities to go on missions. Leo is slightly disturbed by how Donald treats them, such as making them eat food pellets and shower in their capsules, and after learning the kids never left the basement him to offer showing his school to the siblings. The kids are excited to the new world that their stepbrother showed them, however, Adam ends up glitching with his heat vision and the siblings are busted by Donald and Tasha. Afterwards, Leo throws a party in the house while his parents are gone for Bree, Adam and Chase. However, the siblings are busted again, which causes Donald to snap and propose he is sending them to one of his remote facilities, Facility X.

Donald built three look-alike robots of the real Adam, Bree, and Chase to make up for their absence as they train at Facility X. Leo gives his new friends a heartfelt goodbye. However, while Leo is in the basement with what he believes to be the robots, when they reveal to Leo that they are the real Adam, Bree and Chase, this way, they get to stay with Leo without Davenport or Tasha knowing. However, while Leo is away at school, Donald drops them off at a recycling depot at Tasha's behest because she wants their son to be around normal kids and not robots without realizing that they are the real Lab Rats. After his parents don't believe Leo when he tells the truth, he goes to rescue Adam, Bree and Chase himself. At the moment he goes to the recycling depot, Leo is suddenly thrown into the recycling compact shortly after Davenport and Tasha arrive. Adam, Bree, and Chase go to rescue Leo and use their bionics. However, Leo finds the button that shuts off the compactor. Afterwards, Leo prepares to defend his friends, but Donald reveals that he is letting the kids stay and welcomes them home, as long as the Lab Rats keep their bionics a secret, go to school and go on missions.

## 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 is also optomistic for the future, as he expresses hope to see Bree and Chase together, but Bree believes no matter where the four of them are, they will always be a team.

### Powers and Abilities

#### 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. However, he is not strong enough to hold the space elevator for long.
	+ **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 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. He can also use it in Battle, as he used it to take out Taylor back when she was only S-1 by absorbing her attack and then redirecting it back. Leo used it to stop a space elevator
* **Super Durability:** Leo bionic arm and leg are more durable than his non-bionic limbs. For example, when he attempted to punch a hole in the wall during The Vanishing, he showed no pain in putting a dent in the wall not when he kicked Eddy with his Bionic leg.
* **Two Simultaneous Abilities:** when stopping an accelerated space elevator while supposedly saving his father, Leo used his super strength to stop the elevator and absorbed the kinetic energy to slow it down.
* **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.
	+ **Super Kick:** Leo's leg can kick pretty far, as he was able to kick Adam's baseball and kick Eddy up into the air. His kick was able to break through a wall.

### =Non-Bionic Abilities

* **Leadership/Expert 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.
* **Faster Reflexes:**Even before he had Bionics, Leo has faster and stronger reflexes, even though it's not the same level as the other lab rats.
* **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.
* **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.

## Relationships

### Chase Davenport (Brother)

Chase is Leo's cousin/step-brother. Out of all his siblings, Leo appears to be closer to Chase than he is with Bree and Adam. This is most likely due to the fact that both Leo and Chase are the youngest members of their family and are often teased by their older siblings. They often hang out together and finally formed a deep bond and relationship in "Robot Fight Club" when they win a Robot Throwdown against their dad Donald. Leo was also the only one able to snap Chase out of the Triton App by reminding his brother of the good times they had together. Despite their closeness, Leo often teases Chase but not as much as Adam does. They also come to each other for help, as Leo said he would go to Chase when Adam duplicated himself and Chase went to Leo when he couldn't find Adam (who he shrunk down on accident.

Their relationship was temporarily strained in "Lab Rats: On the Edge," when Leo felt underappreciated by Chase and the rest of his siblings and, despite Chase once feeling like Leo in Avalanche. However, the brothers reconciled when Leo saved Chase from falling over the edge during the Hurst Memorial Bridge and water he was promoted to mentor, Chase revealed he couldn't have been any more prouder of his brother

### Adam Davenport (Brother)

Out of all their siblings, Leo and Adam appear to be the least close. They first met in "Crush, Chop and Burn" when Leo accidentally discovered Donald's lab. In the show, Leo will sometimes get annoyed with Adam's stupidity and out of the two of them, Leo appears to be more responsible. Despite this, Adam loves Leo as much as he does his other siblings and will be protective over him, as one of Adam's hidden abilities showed up when he saw Marcus about to kill Leo again. They hang out together, such as "Adam Up." Adam also worried for Leo when his arm got crushed by Taylor and Adam drove the protesters (including Principal Perry) away from Leo with his breath ability. He was proud of his younger brother when he went on his first official mission with them.

Currently, Leo and Adam are running what is left of the Bionic Academy, allowing room for them to grow closer.

### Bree Davenport  (Sister)

Bree is Leo's older step-sister/step-cousin, and they first met in "Crush, Chop, and Burn," where Leo accidentally stumbled upon her and her brothers. He was the first one to show Bree the real world and how to be a teenage girl. Bree makes it her responsibility as Leo's older sister to see her younger brother following the right path, as she told him to take the blame and tell Perry he cheated off of Bree on her test. Like Adam, Bree can be protective of Leo, Bree was concerned when Leo was trapped in the training room with the rest of the bionic soldiers and was scared when Sebastian ordered them to take him out.

Leo tried everything to restore Bree's chip, even going to Douglas, the man who originally created it, to help them.

### Donald Davenport (Stepfather)

    Donald is Leo's stepfather and has been since 2012. Since Leo's biological father is never mentioned, Leo appears to be close to Donald as his father-figure. Donald tries too hard to bond with Leo, and once blew it with him when Donald revealed to Tasha Leo's secret crush when Leo wanted the secret kept between them.

Leo mainly calls him "Big D" because of his position as head of the Davenport Household. However, Leo doesn't have the best relationship with him, even admitting he's not all that good. At the time of season 2 Leo and Donald appeared to get along better, as Donald begin trusting him with missions and being a part of the team. He is fairly protective of Leo as much as the lab rats, as he shouted for Douglas to leave his son alone and was relieved to see his son alive when Leo came in the middle of the battle between the Team and Douglas and Marcus Davenport.

Since Leo matured, Donald finally trusts his stepson, like allowing him to invent things in the lab without Donald in the room and allowing him to find sponsers for his J-Wing stunt. Donald was also concerned for Leo when he learned that his son had been gravely injured, especially when the family feared Krane had kidnapped Leo again; Donald was relieved to see his son and Douglas when they were cornered by Krane and Donald immediately asked Leo if he was alright. However, Donald was angry to learn that his brother gave his son bionics, fearing Tasha's wrath. The Bionic Academy is founded, Donald passes Leo over as a mentor and tells him he has to be a student instead. At the end of Season 3, Donald promotes Leo to a higher level, from beginner to intermediate. In "Unauthorized Mission", Donald is nearly killed trying out Chase and Sebastian's latest virtual reality stimulation, causing Leo to rush to Donald's side and look at him in concern. Unknown to them, Sebastian rigged the stimulation, hoping to get revenge on Leo, the rest of the Lab Rats by taking away their father.

Donald does consider Leo his son, according to the episode "Bionic Houseparty." In "On the Edge," Donald proudly announces Leo is the next mentor after he proves to be courageous in battle by rescuing their family from the Hurst Memorial Bridge. Leo was also happy for Donald and Tasha when they announced that they were going to have a baby girl together.

### Douglas Davenport (Step-Uncle)

    Douglas is the brother of Leo's step-father, Donald, thus making Douglas his step-uncle. They were bitter enemies, but at the time, Leo did not know of his relation to Douglas until "Bionic Showdown."However, Douglas went to Leo for help about Krane and despite his past feelings, Leo decided to listen.Leo's the first to believe Douglas, who tells Leo that he must talk to Donald because his step-father will believe him. Despite believing Douglas, Leo does not defend him and just watches as Donald orders for his brother to leave.

By the second half of season 3, Leo and Douglas were friends, especially after going to his step-uncle for help in fixing Bree's chip. After Leo's arm is crushed, Douglas shows concern for him and tries pulling off the ceiling beam that fell off of him and when he can't do that, Douglas goes to the firemen to save Leo. After learning from the doctor that Leo will never be able to use his regular arm again, Douglas refuses to let that happen and takes Leo to Krane's Warehouse and uses bionic components to save his arm. Despite them being on the government's good sode, Douglas urges Leo to keep his bionic arm a secret because they would take Leo away and Douglas would end up in Federal prison. He also reveals that he made a remote that turns Leo's bionics on and off for the safety of himself and others. Leo steals the remote and activates his bionics. Douglas realizes this and confronts Leo at school, where he sees that his nephew was trying to impress a girl. Douglas promises to teach Leo how to use his arm properly.

### Tasha Davenport (Mother)

Tasha is Leo's mother who he is rather close to. The premiere episode implied they had already been living in Mission Creek prior to her marrying Donald. Leo supports her marriage to Donald; however, Leo told his mother to stay away from online dating when they meet Adam, Bree and Chase for the first time and he sometimes wonders how they ended up together.

When Leo received bionic implants, Tasha was initially furious, but mainly with Douglas, and she often berates Douglas or Donald if Leo's bionics go haywire. She has chosen to support Leo for her son's sake. When Tasha revealed she was pregnant with her and Donald's first child, Leo was happy for his mother and gave her a hug, promising to protect his sister after she was born.

### Daniel Davenport (Step-cousin)

    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 was glad to make Leo and his siblings' acquaintances, mainly because Daniel was glad to have more family members

Leo and Daniel grew closer because of their many similarities, as Leo told his cousin to give Douglas a chance. Daniel eventually became one of Leo's students, and he continued to teach him how to properly control his bionics.

### Taylor (Best Friend)

    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 because she was a blank slate like all the other soldiers, meaning her actions of crushing Leo's arm was not of her own accord. Taylor 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 move on 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

### Logan (Best Friend)

Logan is one of Leo's best friends and a teammate in his own team after Leo grew tired of living in his older siblings' shadow. It is revealed that Logan hero-worshipped Leo, inspired by how he was once a normal kid before becoming bionic.

Logan followed Leo's lead when they were rescuing Leo's family.

### Bob (Good Friend)

Despite appearing in smaller scenes with Bob, they appear to be good friends due to their close relationship with Adam. Since Bob was controlled by Victor Krane, it's implied the two were enemies when the Bionic Soldiers under the influence of the Triton App. When Spin goes to call Leo for help, Bob happily tells his brother to tell Leo that he (Bob) said "hi." However, Leo appears to enjoy teasing Bob at times, because in that same scene, Leo joked with Spin and Bob, taking a selfie with the two to prove how ridiculous they looked. He scolded Bob and Spin for deleting the mission and going on it on their own and despite teasing them about getting stuck in quicksand, Leo was able to pull them out while lifting a log with his bionic arm, thus saving the duo.

At times, Leo can get annoyed by Bob's stupidity as much as he does with Adam, as he wanted to use Bob for target practice with Douglas' pencil bazooka. He also groaned in annoyance when they both touched a skull that was poisoned with a virus Douglas created after Leo and his siblings had already dealt with it when it was taken in by Chase and Bree. After becoming a mentor, Leo became much more strict with Bob, even scolding him for trying to give Daniel his chores on the island and blowing off the lesson. Nevertheless, the two help each other, as Leo was able to convince Bob and Spin to help him escape the bionic soldiers when he was imprisoned with them by Sebastian, Lexi, and Tank.

### Spin

At the start of his debut, Spin has been jealous of Leo due to him being older, allowed to go on missions with Adam, Bree and Chase and being slightly more experienced with his abilities. However, they eventually became friends in "Unauthorized Mission" after Spin called Leo to help get him and Bob out of the quicksand. Leo later gave Spin advice on proving himself: to focus on training and do what Donald tells them to, promising Spin he will eventually get there. In "Bionic Rebellion," Spin was initially on the side of the rebels when he learned Krane was their creator and Donald's reasonings for them being on the island. However, Spin and Bob were immediately convinced to help Leo get out of the training room they were stuck with the other rebels.

### Marcus Davenport (Step-cousin/Arch-enemy)

    Marcus was an Android created by Donald's brother Douglas, therefore Leo's step-cousin. While Adam Bree and Chase were convinced that Marcus was a nice and troubled boy, his act does not fool Leo Dooley, who was the only one to dislike Marcus even before he knew they were family. Marcus framed Leo for breaking his guitar and later, even he was exposed, Marcus revealed his true colors to Leo afterwards threatening him if he ever tried busting him again. Overtime, Marcus came to hate Leo, who mutually hated him back. In Speed Trapped, Marcus tried having Leo killed by imprisoning him in Donald's self-driving car and when he was saved by the Lab rats, Leo learned that Marcus was bionic just like his siblings. Marcus threatened to reveal his siblings' secret to the authorities and therefore Leo's father would be sent to prison and Adam, Bree, and Chase would be taken away by the government.

Leo tried keeping Adam, Bree and Chase away from Marcus, and even risks his life to expose Marcus to protect his family and later, Leo manages to outsmart Marcus by having the robot Marcus apprehended Leo with by pretending to shake his hand, only to lick his hand, remembering how Chase managed to defeat Adam in an arm wrestling match. With Marcus distracted, Leo was able to escape but the evidence he had against Marcus was ruined when Leo's phone fell through Davenport's latest teleportation device. After Marcus and Douglas kidnapped Donald and trapped the Lab Rats in a bionic blocking cage, Leo was forced to save his family but was confronted by Marcus, who had every intention of killing him after being told by Douglas to do so. However Leo managed to outsmart him yet again, this time by hiring a protective vest that his father created. Marcus was upset to learn that Leo had survived when he came crashing down in Donald's exoskeleton creation. Marcus tried to kill Leo yet again until Marcus intervened to protect his younger brother by locking his new ability and blasting Marcus away from Leo. Marcus was later killed by a pile of rubble, ending Marcus' threat to Leo for the time being.

In season 4, Leo and his siblings were shocked to learn that Marcus was resurrected by Giselle Vickers at least two years later and in return, Marcus was (slightly) shocked to learn that Leo was bionic that time. Leo never got the chance to defeat Marcus due to Daniel replicating Marcus's abilities and destroying him. When Marcus regenerated after Leo has thrown his dismantled parts on the floor, the two cousins prepared to fight to the death until Douglas melted Marcus second time, while ironically rescuing Leo from him.

### Victor Krane

An enemy Leo first encountered when Krane abducted him and his mother to get Donald to release Bree, Adam and Chase, Leo and Tasha were nearly killed by this madman. He later confronted Leo and Douglas at the high school. Krane is also indirectly responsible for damaging Leo's arm because he had S-1 attempt to crush Leo with a ceiling beam to keep him and his family out of the way. However, when that failed, Krane tries to get rid of Leo and Douglas again after learning of their survival. Krane was even more surprised to learn that Douglas had given Leo bionics to heal his arm. During "Rise of the Secret Soldiers," Krane brutally injured Leo's father, Donald, however, this enemy was later defeated by Leo's siblings when they combined their bionics.

Leo, like everyone else, thought Krane to be dead until "Space Colony," where Krane was revealed to be alive, and wished to fight against Krane when he put his parents under the Triton App. This time , Krane died for real in Davenportia by Chase's hand

## Romantic Relationships

### Janelle (Girlfriend)

Janelle is Leo's primary love interest in the series through Season 1 to 3 and season 4. He developed a crush on her sometime after his crush on Danielle, recounting that he and Janelle met when he accidentally wandered into the girls' bathroom. Leo confided to Donald about his romantic feelings for her and tried being flashy for Janelle because he was nerdy. When she shows up at the door because Tasha invited her, Leo tried to act cool around her but in truth, Leo did not want Janelle there but was not saying it to be mean. Following this, Leo failed to impress her until he borrowed his stepfather's helicopter and took Janelle out on a flight. She was finally starting to develop a crush on Leo. In "Back from the Future," Janelle invites Leo to a movie and in the same Episode, Leo learns from his future self that he and Janelle will one day marry each other. However, Leo misses the date that was supposed to bring them closer together, as Leo chose to save his siblings over going on the date with Janelle. He tells her the truth the next day but Janelle writes him off and walks away.

In "Air Leo," Janelle tells Leo that even though he did not win the one-on-one tourney against Trent, she was still glad that he tried his hardest, despite initially thinking Leo couldn't stand a chance against him. However, the two seemed to have reconciled, since in "Avalanche," Janelle came over to Leo's house and revealed she liked coming over to the Davenport Household because she liked Leo for the he was rather than the things he owned, rather inventions that Leo stole from his stepfather. However, he accidentally freezes her with Donald's new freeze ray. Despite this, Janelle comes back to Leo's house to watch a movie with him. When Rose comes to visit, she does everything she can to get rid of Janelle by tormenting her and being rude to her. Janelle tried being nice to Grandma Rose for Leo's sake but got fed up when Rose continued being rude to her. Leo wished his grandmother would back down because he wanted to spend time with Janelle, who felt the same way. It took a while for him to get rid of his grandmother but Leo was able to continue his relationship with Janelle.

By season 3, Janelle considered Leo bad luck due to past incidents, such as recounting him freezing her with Donald's freeze ray. However, she invited him to her play and Leo decided to support her (Janelle was previously upset that he apparently hated the idea of coming but Leo accepted it. She was later angry when Leo's defense orbs came and he inadvertently ruined her play. After the world found out Leo's siblings were bionic, Janelle was impressed with Adam, causing Leo to grow jealous. When he tried showing her his bionics, Leo found that he couldn't (because of Douglas deactivating his bionics) and Janelle did not believe him. When Leo reactivated his bionics, he nearly killed Janelle with his laser sphere but proved he was telling the truth.

At the end of season 3 Leo shows her the bionic Academy by getting past Chase; Leo tries impressing Janelle but Spin, one of the students there, pretends to get hurt by Leo's laser sphere generation and make Leo look bad. However, Spin is eventually busted. In Season 4, it is revealed that Leo and Janelle are still dating despite the incident with Spin in her last appearance. She wanted to spend more time with Leo due to his duties on the island and threatened to break up with him if he did not visit her on the mainland once in a while.

It is revealed in "One of Us" that they are dating but not boyfriend and girlfriend

### Danielle (ex-crush)

 File:Lanielle.png
Danielle was the name of a girl that Leo had a crush on in the episode "Leo's Jam." He has in love with her so much that he would often act as a footstool for her two-layer feed on instead of the ground and sent her at least 87 e-mails. Additionally, she doesn't remember Leo's name and calls him Lenny. However, both Adam and Chase also fought over Danielle as she kept turning her attention to each of the three Dooley-Davenport brothers and at the dance, Leo won Danielle over with a dance he performed with his aunt and her book club. However, Leo realizes what he did was wrong to his brothers and apologize to them. Danielle is never seen nor mentioned again afterward and since Leo has a crush on Janelle, he no longer has a crush on Danielle.

### Shelley (Ex-Crush)

Shelly was the name of a Droid phone that Leo had an unhealthy crush on in "Bionic Dog." Bree found this disturbing and pointed out that it was wrong for Leo to have a crush on an inanimate object. As soon as Bree changed the phone settings to Liam, a phone with a British accent, the two siblings fought over it. At the end of the episode, Otis urinates on it, passing both Leo and Bree to lose their interest on the phone.

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 sneaked Douglas into Davenport's lab. Anti-social and both mocked for their intelligence. 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.) 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 later became mentor and student. They get reckless with their bionics when they first got them.  Excited but feeling lost when in their family, the Davenports. They lived their whole lives without bionics.
* Leo went on his first mission and got his first mission suit in "Rise of the Secret Soldiers."
* According to Donald, he cannot handle high fiber cereal. (Three Minus Bree)
* Douglas implies he left a pen in Leo's bionic arm when he was constructing it. (You Posted What?!?)
* On Adam's website, it says he's the 8 year old mascot of the Lab Rats called Lee Clooney (Rise of the Secret Soldiers).
* According to Douglas Donald killed most (if not all) of Leo's pets.
* Leo is one of the three characters to give a female enemy the nickname "Cupcake," giving it to Taylor. Eddy nicknamed Tasha it, as did his step-cousin Marcus to Bree
* 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).
	+ Leo did eventually become one in "Lab Rats: On the Edge."
* He wasted most of his life playing video games. (Night of the Living Virus)
* Leo's voice deepened in Season 3 due to Tyrel Jackson Williams going through puberty. (Sink or Swim). It was beginning to deepen in the season 2 finale "No Going Back."
* Considers Donald his father. ("Left Behind), Adam, Bree, and Chase his siblings ("Leo's Jam" and "Smart and Smarter") and considers Douglas his uncle ("Face Off").
	+ Out of all his family members, Leo connects with Daniel and Chase the most, possibly because they are the youngest members of the family.
* Marcus and Taylor were Leo's arch-enemies. However, Marcus was crushed under a pile of rubble and Marcus began hating Douglas more than Leo because the former was his creator and abandoned him to his first death. Taylor reformed in "One of Us" and eventually, became one of Leo's best friends.
* He never got the chance to fight Marcus due to Daniel replicating Marcus' bionic abilities and Douglas melting him.
* Season 3 was about Leo becoming bionic.
	+ The episode "Parallel Universe" foreshadows him becoming half-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.
* Despite being only partly bionic, it is revealed in Under Siege that Leo glitches. Douglas didn't take into account this could happen, but he did make Leo an arm capsule at the end of the episode.
