Disney XD's Lab Rats Wiki

Leonard "Leo" Francis Dooley is an entirely bionic human in a parallel universe and a counterpart of Leo's non-bionic self. In Parallel Universe, he was temporarily replaced by the regular Leo, who received his bionics for that time.


It all started when Leo was in the lab and was pulled into another dimension by a wormhole that was created by Donald Davenport, and when Leo got there he replaced Parallel Leo for a day. He goes upstairs to discover their house is completely different, he has bionics, and Tasha is the brilliant scientist, not Donald, who is her lab assistant.

Leo talks to Parallel Donald, discovering he is a terrible scientist, and everything he makes either explodes or doesn't work. He tells Parallel Donald about the wormhole and how he's in a parallel universe, although he didn't believe him. Leo goes to the parallel school, seeing Parallel Perry (who is actually nice, other than the actual Perry) and Adam, Bree and Chase's the last name is Henderson, not Davenport. Leo talks to them, but they act like they don't know him, implying they don't know Parallel Leo.

Leo makes the mistake of showing the Hendersons his bionic secret, making them freak out. Later that day, they tell Leo his bionic secret is safe with them. This turns out to be a lie, as they get a government agent over at the school, to take Leo away, but he escapes (along with Parallel Donald who was there to pick Leo up from school).

They go home, but later, more government agents swarm their house, causing Parallel Donald to faint, and they both get captured and handcuffed. One of the agents, (Agents Gordon), tells them it will explode if he tries to break out of them. Parallel Tasha is being assisted by an agent going down the stairs, when they take her outside, she hints something to Leo, which is actually telling Leo that he has new bionics. Parallel Donald figures this out, and tells him about geo-leaping, which they do, and end up at the school.

Parallel Perry finds them, and tell them agents are trying to find them. She helps Leo and Parallel Donald, and they try to escape. Adam, Bree and Chase Henderson look for them, and find them. But Leo super speeds with Parallel Donald back to the house, where the agents are still there, but instead of running away again, Leo fends them off with his bionics, and they run down to the lab. Leo tells Parallel Donald about the fuser, and about how it worked, which helped Parallel Donald fix it, and make it work. Parallel Donald tells Leo what will happen when he goes back, saying everything will go back to normal, and they won't remember anything. After their goodbye hugs, Parallel Donald fends off the agents that try to break in, and Leo jumps into the proton fuser, and everything goes back to normal.

Powers and Abilities

Leo's Electrokinesis

  • Electrokinesis: He harnesses the static electricity from his surroundings and utilizes it to create lightning bolts.
  • Super Strength: This ability manifested once: when Leo tosses the keys to Tasha and he ends up shooting them through the door, knocking off the neighbor's mailbox.
  • Super Speed: Leo uses this ability three times, all in an effort to either escape or to defend Donald and himself.
  • Super Intelligence: Donald tells Leo that he knows he has super intelligence.
  • Geo-leaping: Donald reveals to Leo one of his newly uploaded abilities as they attempt to escape. Leo molecularly transports himself (and whoever he touches) from one place to another by thinking about his destination.
  • Two Simultaneous Abilities: It was shown that when Leo grabbed 2 Agents he used Super Speed and Super Strength to throw the Agents across the Table in the kitchen, and still did not faint, like Chase does.
  • Martial Arts: Parallel Leo is good at fighting just like the Lab Rats, he used Martial Arts, to take down Special Agents in their house.
  • Bravery: Leo was brave enough to fight multiple Government Agents at the same time by himself.
  • Tactical Thinking: Leo has a gift for sizing up a situation and coming up with solutions, even while under extreme pressure. Leo knew how to get back to his real dimension, he immediately knew that Davenport's Proton Fuser, could get him back to his real universe.


  • Imprecise Geo-Leaping: Because his Geo-Leaping ability is fairly new, it has not yet been perfected, so it sometimes brings Leo to the wrong location.
  • Uncontrollable Electrical Generation: When he puts his hands in front of him and accidentally uses this ability, he tears down everything that is not immune to lightning.


  • Leo was 15 in Parallel Universe.
  • He is a Bionic Superhuman, and is probably the only one of his kind in his universe.
  • He has the same personality as the Leo in the original universe. However, this might not be his true personality, as parallel Donald thought he was imagining things.
  • Parallel Leo is completely bionic, while the real Leo is bionic only in his right arm and left leg.
  • Unlike Chase, when he uses two abilities at once, does not faint.[2]
