## Season 3

### Facing Victor Krane (Taken)

In the beginning of the Episode, Douglas contacts the team to warn them about Krane but Leo, his siblings and their father didn't believe him and wants to hear none of it and promptly hangs up the video chat call. When Leo goes to school the next day, Douglas goes to him for help and warns him that Krane is coming after Adam, Bree and Chase. A video convinces Leo enough that Krane is no laughing matter and that Douglas may be telling the truth. However, Leo and his mother are kidnapped by Krane causing Donald to go rescue them but Krane goes to hurt the Lab Rats. Donald, Leo and Tasha return to the house where Donald kicks Douglas out and threatens him with his thermal blaster.

### Helping Bree (Which Father Knows Best?)

After Bree broke her chip, Leo went to Douglas to help her. Leo played a part in Douglas' reconciliation with Donald by he and his siblings encouraging him to give Douglas another chance after Douglas apologized for hurting the family.

### Becoming Bionic (You Posted What?!?)

The secret of his siblings were revealed when Krane posted a Video of the Lab Rats fixing a pipeline and using their Bionic Abilities. When the feds came to arrest Adam, Bree and Chase, Leo escaped the house with Douglas where they retreated to the school but Leo came up to the conclusion that the mission was a setup. His suspicions are confirmed when he and Douglas investigate the pipeline his siblings fixed and see that the girl who recorded them was Bionic, but Douglas and Leo thought that Krane used a cybercloak and a cybermask to pose as the girl and post the video, knowing full well the Feds would arrest their family. However, Krane and S-1 confronted Leo, Douglas and Principal Perry against Victor Krane and Taylor. It left Leo severely injured when Taylor used Molecularkinesis to let a ceiling beam land on top of his arm, crushing it. Since the doctor couldn't heal Leo, Douglas took him to Krane's abandoned warehouse, where he used bionic technology to heal Leo's broken arm. Leo was encouraged by Douglas to try his now healed arm out and Leo discovered he was Bionic after throwing a laser sphere for the first time. Douglas also tells Leo he has super strength in his arm and how the laser spheres work.  Soon, they are confronted by Krane and S-1 until Adam, Bree and Chase arrive looking for their brother. Leo helped apprehend Krane by knocking him out with his laser sphere generation ability, with Leo revealing his secret to his siblings and Donald. Subsequently, Tasha and Perry learned when Leo accidentally crushed Perry's hand when shaking her hand with his bionic one.

At first, Leo struggles with his new Bionic arm until Douglas decides to mentor Leo on him on how to control it.

### Rise of the Secret Soldiers

Leo officially goes on his first mission with the Lab Rats and his father and uncle to face Victor Krane's secret soldiers. He gets a mission suit and a new ability from Douglas called Energy Transference, which he uses to absorb an attack by S-1 and reflect back to her. After seeing Donald gravely wounded, Leo goes to his side but finds that his father is not breathing. They have him taken to a hospital, where Leo gets a call from Tasha. He tells his siblings and uncle that Donald just got out of surgery but fears that it is touch and go.

## Season 4

During Sebastian's rebellion uprising, Leo was trapped in the training room with their bionic soldiers. To hurt Adam, Bree and Chase, Sebastian ordered his siblings to take out the original Lab Rats' younger brother. However, he escaped with the help of Spin (who used his abilities to "drill" a hole for Leo to escape him) and Bob (who distracted the other kids with a fairly terriblemagic trick).
Leo joined his siblings in fighting against Sebastian, Lexi and Tank. Sebastian tried taking out the Lab Rats; however, the four siblings provoked Sebastian so he could overload using all his unlocked bionic abilities.

Leo and his family went to rescue the kids but were lured into a trap by Giselle, who revealed that Marcus was alive. He subdued Leo, Adam, Bree and Chase when they attempted to attack him and Giselle trapped the teenagers with the other bionic children and hoped to watch Donald and Douglas suffer as she tortured their children. However, Leo was immune to the effects of their cage because the bionics were only in his arm and leg. He used his bionic leg to break the cage, letting so the others escape while Giselle destroyed all their bionic chips. Leo went to take Marcus down but Daniel had already done so. After Giselle was defeated, the Lab Rats and their family returned home, when Leo learned his mother was expecting a baby girl. Leo was left alone in the lab to reminiscent and also throw Marcus' remains on the floor.
