## Biography

### Chapters 1-20

In this season, Leo is in his clumsy phase of life who is still trying to fit in at school. He meets the Lab Rats and introduces them into the real world and takes them to school. Leo and the Lab Rats became friends easily and Leo had to save the Lab Rats for a numerous amount of times. He meets his future self in Back From the Future.

### Chapters 21-46

He becomes more responsible, and tries to stay on Donald's good side. He seems to help the Lab Rats more on mission rather than getting them into trouble. In this season, he matured into a fresher stage. His knowledge allowed him to get promoted to a Mission Specialist. He tries to convince the Lab Rats that Marcus is up to no good. In Chapter 28: Parallel Universe Leo used one of Donald's inventions to travel to a parallel and acquired temporary bionics. (Chapter 28: "Parallel Universe")

### Chapters 47-72

Leo, as Mission Specialist, is maturing in a higher stage. He had a change in personality being more responsible and trying to outsmart his opponents (Trent for example). Leo also begins to create his own inventions rather than breaking his step-dad's (Scramble the Orbs), though they have ended up causing damage. He became bionic in You Posted What?!?, thanks to Douglas fixing his damaged arm. Though his siblings' bionics were revealed to the world, Douglas urged him to keep his bionic arm a secret. However, in Rise of the Secret Soldiers, Leo accidentally revealed his secret to an angry mob of protesters. He later became an official member of the team. Douglas also unlocked Leo's new ability, which is to absorb any energy source as he used it on Taylor to get his revenge. He gets re-located to The Davenport Bionic Academy in First Day of Bionic Academy, although was a student, unlike his siblings. Leo is now a full member of the team, as he got a mission suit in Rise of the Secret Soldiers, and now goes on missions with Adam, Bree, and Chase.

### Chapters 73-99

Leo, along with his siblings, continue to live at the Davenport Bionic Academy. Leo is a beginner student but wants to be a mentor. He gets a capsule for his arm in Under Siege. In Mission Mania we see Leo going on missions (Due to an ad he created). In Space Elevator, Leo is promoted to Advanced. He gets bionics in his leg in due to his injured leg getting crushed. He prepares himself for any major threats at the academy. He is also doing everything he can to prove himself. In Lab Rats: On The Edge, it is shown that Leo is now an Expert level student. He gets jealous of his siblings and forms his own bionic team. After causing Taylor to lose her eyesight, he quits the academy. Later, he saves his family and performs heroic acts with his regrouped team and afterwards he is made a mentor at the academy. When the family team split up in The Vanishing, Leo volunteered to oversee the Academy, along with Adam.

## Personality

Leo was the only non-bionic kid in the Davenport-Dooley family until You Posted What?!?, where he becomes bionic thanks to Douglas giving him bionic components because his arm was damaged by Taylor. Later, in Rise of the Secret Soldiers, he unlocked a new ability. He is supportive of his mother's marriage to Donald Davenport. On their first day moving into his stepfather's mansion, he met Adam, Bree and Chase. He was attached to them soon and treated them as his own siblings. At school, Leo is considered the kid at the "bottom of the food chain" since he is one of the smart kids (Crush, Chop and Burn). However, with the help of his siblings, he was able to climb up the 'food chain' and starts to get noticed in school.

Leo is loyal, caring, and intelligent. He has demonstrated these qualities in various situations, especially when his family is involved. In Season 1, he showed his loyalty to his siblings by staying with them despite the possibility that he could be hurt (Rats on a Train); by sacrificing his date with Janelle—and ultimately, his safety—when the possibility of them dying became imminent (Back From the Future); and by keeping their secret of using their bionics at school despite its end result of him not being able to go to an event he's been looking forward to going to (Mission Invisible). He shows that he cares for them and about how they feel in isolated events, like when he allowed Chase to redeem himself by letting him use his idea to defeat the exoskeleton (Exoskeleton vs. Grandma); when he apologized to Adam and Chase for showing them up at the dance (Leo's Jam); and whenever he bonds with Donald (Can I Borrow the Helicopter?). His concern over their well-being can be seen more in Season 2. Upon Donald's request, he kept watch over his siblings, especially when they were around Marcus (Speed Trapped). After finding out the truth about him, he became more alert for them, even risking himself once again to prove to his family the danger that Marcus presents (Leo vs Evil).

His intelligence and problem-solving skills have come to play in several instances. Using his knowledge of science and street smarts to stop a high-speed train (Rats on a Train) and applying the simple things he observes to drain out a toxic gas during a mission (Missin' the Mission) are two instances. Despite this, on several occasions, he fails to take account of the potential consequences of his actions.

However, Leo can be manipulative and self-centered at times, which often stems from his unpopularity. He has taken advantage of his siblings' bionics multiple times. He has used Bree's view of him as her little brother to catch a ride to his classes and get his 'forgotten' homework (Smart and Smarter); Adam's super strength to win the school fitness challenge (Death Spiral Smackdown); and the father-son relationship he's formed with Donald to be able to see a movie his mother forbade him to see (Chore Wars). Leo also quickly turns arrogant if things start to go his way, and acts stuck up, normally leading to him falling back to the ground painfully. He also often blows his achievements or duties out of proportion, making himself out as far more important, popular, and successful than he really is.

Leo also has a habit of creating his own problems; for example, he got trapped in Principal Perry's private elevator, which he was using despite students being forbidden (Chip Switch); him convincing Bree to misuse her bionic vocal manipulation leading to both of them being discovered (Bro Down) and disabling Chase's bionics and inadvertently amplifying his bionic aggression (Spike's Got Talent ). He also often lies, and uses lying to try and solve his problems, normally unnecessarily; however, this backfires on him as it has left others distrusting of him, meaning he sometimes has trouble convincing them even when telling the truth, as demonstrated with his efforts to tell them Marcus is evil.

Leo has a crush on Janelle, but didn't go for it cause of Ella. In a possible future seven years from the present (Back From the Future), Leo and Janelle are a couple. In Leo's Jam, he had a crush on Danielle, but he chose not to pursue that (because Ella Garcia wanted to go to the dance with him, eventually they got married and had a son).

## Family

### Adam Davenport

*Main article: Adeo*
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 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.

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

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

*Main article: Doneo*
Donald Davenport is Leo's stepfather. Leo mainly calls him "Big D" because of his position as head of the Davenport Household.

In No Going Back, Davenport did not want Leo to worry. Leo is Donald's lab assistant. He 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.

### Douglas Davenport

However, they became friends in Taken, when Douglas warned Leo about Krane. Leo convinced Douglas to help Bree fix her chip in Which Father Knows Best?. Leo and Douglas have bonded more over the course of You Posted What?!?, as they made an assumption that Krane was the girl and Douglas helped him become bionic and heal his arm in the same episode. 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

*Main article: Tasheo*
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.

In You Posted What?!?, Terry Perry says that what bonds them is that they almost died together.

### Marcus Davenport

*Main article: Mareo*
Marcus is Leo's android cousin and was his main enemy in chapters 1-46. Marcus antagonizes Leo and threatens him since he considers him a hindrance to his plans due to him being aware of his evilness (Concert in a Can). He tried to kill him several times but always failed. Marcus's last attempt to kill Leo is what caused his death.

### Taylor (formerly)

*Main article: Tayleo*
Leo is Taylor's former archenemy. Like Marcus, she has a lot of bionic abilities, which also includes Adam, Bree, and Chase's, and is extremely hostile to him, always looking forward to destroying him. Taylor was the one who destroyed Leo's original arm. Leo later got his revenge when he defeated her in Rise of the Secret Soldiers. Leo still held a grudge against Taylor, for as soon as he saw her in One of Us, he threw his laser sphere at her without considering she wasn't evil anymore. However, they made up at the end of the episode and became friends. Taylor seems to care about Leo more than anyone else at the Academy. Leo helped Taylor choose a new name for herself, and they formed a new bionic team with Logan. They can also combine their abilities, and they also constantly encourage each other and help each other out, as shown in Lab Rats: On The Edge.

## Powers & Abilities

### Bionic Abilities

In Crush, Chop and Burn, Part 1, John gave Leo a bionic chip with all abilities that John creates, cause Leo is John's person to test the abilities and if they work Leo can keep them. In You Posted What?!?, Douglas recreates Leo's right arm with bionic technology, replacing damaged parts of it with bionic components. Leo's right arm and left leg are bionic and all bionic abilities Leo has been in his arm and leg, as he has bionics fully integrated into his nervous system, as his bionics are directly connected to his brain or in his neck. Douglas made a remote deactivation function to control Leo's abilities, but it was later destroyed.

* **Bionic Arm:** Leo received this bionic arm after Taylor crushed him in You Posted What?!?. This was his first time receiving Bionics other than Parallel Universe. It is shown that Douglas recreated Leo's right arm with bionic technology to replace his original, damaged arm. It's current known capabilities, according to Douglas, include:
	+ **Laser Sphere Generation:** In You Posted What?!?, according to Douglas, Leo can generate laser energy and form them into laser spheres from his fingers and shoot them from his hand. This is also Leo's main bionic ability as being the one he uses the most. It is also strong enough to knock out Krane and they can set things on fire. The laser bolts can knock out powerful bionic humans, such as Taylor, or even Krane as stated above, or blast objects to pieces or blast aside metal.
		- **EMP Generation:** Leo discovered a brand new bionic ability where he can combine laser spheres with another bionic person (usually Taylor) to generate an EMP to knock out any electrical equipment.
	+ **Energy Transference:** This is one of Leo's hidden abilities. Douglas unlocks this ability for him to fight the bionic army. This ability can absorb any type of energy source and it can be used medically (though this is highly discouraged due to the life-risks). Leo defeated Taylor for the first time with this ability. While Leo used the ability to heal Donald, it's not clear if it can be used to bring a dead person back to life. He can also absorb kinetic energy, which was how Leo was able to catch the falling space elevator.

* **Super Strength (Bionic Arm):** Just like his big brother Adam, Leo's arm is shown to have superhuman strength, allowing him to be strong enough to crush Perry's hand and making it become swollen. And in Armed and Dangerous, Leo uses his bionic strength to lift the couch with one hand without visible strain in a similar manner to how Adam lifted it one-handedly. Also, like Adam, he was not visibly discomforted by the weight of the couch and balanced it well in his hand. In Bionic Rebellion, Leo used his super strength to throw Tank out of the window. However, some metals take him a while to break with his arm. Shown is Space Elevator Leo had his leg crushed so he now has a bionic leg. He can kick really hard and send a ball going flying. He later used this against Human Eddy and sent him flying into a wall. He also has a Bionic Chip that was given to him by his Big Brother John.

### **Bionic Chip Abilities:**

* **Super-Strength (Bionic Chip)**

* **Super Speed:** Just like is big brother and sister he is able to move at super sonic speeds running faster than 3,700. Leo was given this ability during the first Chapter of the Lab Rats Fan Fiction
* **Super Intelligence:** Like his big brothers John and Chase he is able to have the knowledge of the world thanks to the ability since he has a bionic chip.
	+ **Mental Database:** Leo possesses an incredible and extensive mental database; using it, he can match things that he sees and quickly identify them. It holds information like fingerprints (Quarantined), paintings (Hole In One) and people.

* + - **Fingerprint Recognition App:** Leo can scan the fingerprints from anyone off of his database. (Quarantined) (Taken). This is shown in The Bionic 500 when he scans Joey Logano and searches his database to find a match.
			* **Facial Recognition:** This is shown in The Bionic 500 when he scans Joey Logano and searches his database to find a match.
* **Electrokinesis:** Leo is able to shoot lighting from his fingers when it builds up it shoots out a big force and can throw somebody back to the point they'll hit the wall
* **Plasma Grenades:** Leo like his Brother John and Cousin Marcus can shoot plasma grenades and **It is said that you could kill someone with this ability.**
* **Lightning Manipulation:** The user can harness green lightning in his palm and use it as a weapon. It is presumably powerful enough to kill a person. Emma survived the electricity with one of Donald Davenport's protective vests
* **Pyrokinesis:** Leo is able to shoot a continuous stream of fire from his hands much like Kaz from Mighty Med Fan Fiction and Lab Rats: Elite Force
* **Pyro-Thermal Nuclear Body Blast:** Leo is able to push his arms back and his arms start to have fire on them and when he jerks his arms forward. The Person he fires at goes flying backwards like Bree's Thermal Nuclear Body Blast from Elite Force when she gains Superpowers.
* **Flight:** Leo is able to Fly due to John creating the ability and John and Leo are the one Bionic Superhumans to have that ability.
* **Laser-Bo:** Leo 's fist can generate a Laser Bo staff that is very useful during combat, it is strong enough to knock Adam through the air. Sebastian had a similar variant of this ability, in the form of a pitchfork.
* **Two Simultaneous Abilities/Three Simultaneous Abilities:** John gave Leo access to the second generation bionic chip, then third generation bionic chip in chapters 47-72
* **Geo-Leaping:** Allows the user to teleport themselves and others from place to place, sending their molecules in the form of signal anywhere the user thinks of.
* **Super Durability:** Leo bionic arm and leg are more durable than his non-bionic limbs. Along with his bionic chip
* **Bionic Leg**: In Space Elevator, Donald gives Leo's left leg bionics because it was broken by the elevator, and he was afraid he couldn't go any missions. The only known capabilities include super strength as shown when Leo kicked the basketball a great distance using his leg and when it bounced back, it knocked Donald down. Leo used this to sent Human Eddy flying into a wall. (Human Eddy) His leg was shown to be even stronger than his bionic arm, being able to tear through a steel wall, something his bionic arm only put a big dent in. (The Vanishing)
