Leo moves in with billionaire stepfather, Donald Davenport. In an attempt to find his room in the new house, he stumbles into the lab where he finds super-humans, Adam, Bree, and Chase. They each have unique superpowers, Adam with super strength and heat rays coming from his eyes, Bree with super speed and agility, and Chase with a super computer brain. Leo realizes he just found some new superhuman friends and convinces Mr.Davenport to let his new friends go to school, when all goes awry. The main point of the show is to express their adventures and missions, inventions, and Leo trying to become part of the Lab Rats team. Written by HAPPI PONIO

On the superteens' first Donald-sanctioned day at school, there's a fear that Chase's Commando App might kick if he feels personally threatened - which is exactly what happens after Adam breaks the status quo by sitting at the cafeteria cool table, thus riling the football players. Chase becomes Spike, a never-back-down alter-ego, who shames the star quarterback and his entire defensive line. The ill-tempered and intimidating Principal Perry gets word of this and seeks to restore her football players to their former rule-the-roost standing but finds Spike more than a match for her. She finally gets him to agree to a grudge match football game, pitting Leo and the inexperienced bionic teens against the seasoned school team for ownership of the cool table. Meanwhile, back at home, Donalds wants to work but a bored Eddy wants to play. Written by statmanjeff

With the Mission Creek Dingo Dance coming Saturday, Leo would like to go with Danielle, a beautiful upperclassman who's only used him as a footstool in math class. Chase and Adam endeavor to help Leo catch her interest, but a scheme to make Leo look heroic only puts her eye on Adam. Chase's effort to sway her interest from Adam to Leo only swings it onto himself instead. There's only one thing for Leo to do: Ostensibly forgive Chase and teach him the refrigerator dance. Meanwhile, a boy named Ethan would like to ask Bree to the dance, if only her first-date jitters didn't send her running away at superhero speed. Written by statmanjeff

Donald's latest tests on his technologically enhanced teenagers are interrupted by an emergency, becoming their first true mission: His high speed train filled with highly explosive nuclonium is speeding out of control and heading for downtown Welkerville. With his mom just hired as an on-air news reporter for this event, Leo feels left out of the adventure, so he smuggles himself inside a carrying bag to join it.

As Chase and Donald prepare for their annual Internet technology exhibit, Tasha's mother Rose decides it's time to visit. Hoping to pass as normal, Tasha presents the bionic siblings as the house staff - chef Adam, personal trainer Bree and Leo's male nanny Chase. Chase is actually smarting from Leo worming his way into the annual Internet exhibit (subconsciously a father and son time for Donald and Chase). Feeling displaced, Chase sabotages the exo-skeleton suit that Donald is allowing Leo to demonstrate. Instead of merely malfunctioning, the suit goes berserk, destroying the lab and threatening the house inhabitants, which isn't what Chase had in mind as it forces the family to consider which is worse - rampaging technology or a judgmental grandmother.

Tasha has always thrown Leo a surprise birthday, so Leo's genuinely surprised when an awards banquet truly prevents her from arranging one for once. The superteens (who've never had any birthday parties of their own) decide to throw him one. Unfortunately, caught up in the excitement, they totally forget to tell Eddy to release Leo from the basement to join in, leaving Leo rightfully embittered. All hope that Donald's afore-mentioned wow-factor gift will appease Leo, not knowing that Donald earlier removed it from its box and broke it, leaving the superteens to brainstorm over what Leo would truly want for his birthday.

For her annual Fitness Challenge Week, Principal Perry introduces a carnival ride version of big time wrestling called Death Spiral Smackdown. Leo forgoes friend Gordo to team up with Adam so he can ride his bionic coattails and win Fitness Week for a change. Adam has ethics against using his super-powers in school competitions, so Leo spikes Adam's cereal with power pellets from the lab to put his adrenalin out of control and decimate the opposition. It's all good till Leo learns there can be only one winner, with members of the winning team competing against each other in the end - conniving little Leo versus big, amped and out-of-control Adam. Meanwhile, Chase gets back at Bree for lying to him by engaging his Override App and igniting a public humiliation battle. Written by statmanjeff

Unable to have a phone conversation without the boys pestering her mercilessly, Bree asks for her own room, but when she gets it she finds Tasha unable to leave her alone. Leo trusts Donald with a private matter of the heart, a trust which Donald shortly thereafter breaks, sending a manipulative Tasha to force the two kids together. With the secret lab to themselves, Chase and Adam go at odds over the decor - pop art clutter versus zen yoga tranquility - and try dividing the living space in half. Written by statmanjeff

When Bree, Chase and Adam discover that Leo gets an allowance for doing chores, they want in on the action, but earning a little bit of cash goes quickly to their heads.

With Adam and Bree's money already spent, they target a miserly and reluctant Chase to buy the music box back. Meanwhile, Leo bonds with Donald over the latest Pig Zombie movie that Tasha forbade him to see. Written by statmanjeff

To appease Tasha's request for a totally tech-free weekend, Donald takes everyone to the beach. The bionic teens expect a day of fun, sun and sand, but a massive solar flare eruption anchors them within the RV (which, unknown to Tasha, doubles as a mobile action lab), awaiting its supercomputer to calculate when to launch a rocket that'll block the troublesome flares. As Donald struggles to sit through a day amidst nature with Tasha, boredom gets the better of the superteens, putting them well outside the RV when the computer finally gives the signal to launch. Adding further grief is an unhelpful beach sheriff making their vacation everything but relaxing. Written by statmanjeff

Tasha wants Bree to be more ladylike and Leo to lay off video games. To these ends, Bree is permitted a slumber party while Donald is coerced into taking Leo on as a lab assistant.

In the lab, Leo proves to be a deterrent to Donald's progress, so Donald assigns him the tedious duty of watching a computer download just to get him out of the way. Bored, Leo decides to speed things up by dropping the firewall, which allows a virus to enter and corrupt Eddy. Now evil and in control, Viral Eddy traps and terrorizes the house inhabitants with intent to kill. It's up to the boys to employ their computer gaming skills and set things right.

Adam and Chase quickly hit it off with new student rock guitarist Marcus. Chase proves himself Marcus' equal after accessing a guitar-playing download, and the three form a band with Adam on drums. Leo, finding himself on the outskirts of this bond, views Marcus with dislike till Marcus allows him in on the cow bell. Leo's behavior could all be chalked up to a simple case of insecurity and jealousy except Marcus next perpetrates a heinous act on himself and blames it on Leo, leaving Leo's professions of innocence disbelieved.

That leaves Leo to entertain and distract Marcus alone while the rescue mission gets underway, but not even Leo knows the sinister threat that Marcus truly poses.
