Connor moves to Bubble Town and meets the Botties: Abby, Mong, Chip and Hela. In order to join the club he has to fix a robot in 24 hours. He chooses Cubix, the 'Unfixable Robot.' When Hela brings a WeldNFix gone mad to the Botties Pit, Dr. K shows up to steal it. Cubix awakens just in time to save Connor and together, they fight Kolossal and Dr. K to save the Solex infected bot.

Connor now has a robot of his own, Cubix. Unfortunately, his dad Graham doesn't feel the same way about robots- and kicks Cubix out of the house. Charles, the mayor's son, also has a new robot- Quixtreme 5000! While they're playing cat and mouse at the Botties Pit a Lectrix shows up- not feeling well. Hela volunteers to talk to Graham, which only makes things worse...while the Lectrix's Solex goes unstable at the charging station. Dr. K shows up with Kolossal and the battle for Solex ensues.

When the power keeps cutting out in Bubble Town, Abby decides to take matters into her own hands and catch the culprit. The rest of the Botties join her mission and soon they are led into Bubble Town's sewer system - Sewwix is the offender. Soon enough Dr. K and Kolossal show up and manage to break a gas main - sending the Botties on a race to save Sewwix, get Solex, and save Bubble Town from exploding!

Raska, the beloved spokesperson for Robix Corp is in Bubble Town shooting a commercial for the new Delishix. The Botties sneak onto the set, but not very stealthily - they get caught. Raska thinks that Connor would be the perfect star for the commercial and his house the perfect set. Unfortunately, Delishix is not the perfect robot and it goes berserk! The Botties chase the Solex infected robot, but so does Dr. K and it's a fight to the finish!

Robots are disappearing in Bubble Town, but the Botties are on the case! The Botties think Dr. K is responsible, but when Dondon narrowly escapes being disintegrated by Disposix, he knows otherwise. Unfortunately, Dondon's voice module gets broken in the attack and leaves him speechless. Finally, Disposix's Solex becomes too unstable not to notice and, of course, Dr. K shows up to collect it. Knowing he'll have to put up a fight he brings Kolossal and Katastrophe to ensure his success.

Mong installs a HERO unit (Hazard Early Response Option) in Maximix that he gets from his friend Ixtinguix- the Bubble Town Fire Chief. But when Ixtinguix starts acting strangely the Botties suggest that he come to the Annual Robot Inspection at Town Hall for a check up. The strange behavior turns into flame-throwing rage- it's Solex! And soon Dr. K shows up with Kolossal and Kannon to take kontrol of the situation.

As a hurricane approaches Bubble Town, Connor and his dad have a huge fight and Connor runs away...to Abby's house. As the storm intensifies Graham gets worried and goes out to look for his son. Hela joins him and they drive all over town. Connor now starts to worry about his missing dad and rushes to a highway crash he thinks Graham was in...he doesn't find him there, cause Graham's car is teetering off the side of a cliff! The Botties find them just in time for Cubix to save them all.

One of Dr. K's robots, Attractix, runs away from his lair- infected with Solex- and heads straight for Bubble Town. Once there, his super magnet wreaks havoc on the otherwise peaceful town- collecting everything including Dondon! Dr. K chases his AWOL bot with Kolossal and Krab but the magnetic field is too strong even for them! Cubix uses his drill mode and brings Connor close enough to save the day- and get the Solex!

Racing through Bubble Town gets the Botties into trouble again...this time at the Robot Graveyard. A strange robot named Konfusion appears and leads them into the Robot Zoo. Once they get there, they realize they have just set foot into Dr. K's secret lab

It's time for the Annual Robot Grand Prix- promoting technology and beauty- and all the Botties are working furiously on their robots to win! Even Charles is planning to take home the prize with his Quixtreme 5000. Unfortunately, Quixtreme is infected with Solex! Dr. K, Kolossal and Klawber show up and instead of the final round of the Grand Prix they go another round with evil!

While Hela experiments on Solex, Dr. K and his alien boss launch an attack on the Bottie's pit. The Botties beat the battle-bots, but it was a fake attack! Raska shows up expressing her concern for their safety and offers Hela the Robix Corp facilities for her research. The Botties go to Robix Corp where they are treated like royalty...until a new robot goes berserk and almost kills them! Hela decides to stick to the Pit so Raska gives them new miniature safety robots...which turn out to be evil decoys that want to blow up Cubix! Cubix sacrifices himself in order to save everyone else.

Connor and the rest of the Botties go searching for Cubix, or what's left of him only to find that he has been kollected by Dr. K! Thanks to Attractix's returned memory, they fall into Dr. K's lair, literally. Once inside, they have to overcome many obstacles until Connor can get to Cubix...he finds him, but only after K has stolen his Solex crystals. Connor also finds out that Raska is an alien and that Nemo has been held prisoner there! Luckily they fix Cubix and escape the clown tower just as it transforms...into the world's largest robot!

Connor, Cubix, and the Botties (in Dr. K's battle bots) attempt to save Bubble Town from Dr. K's enormous robot. Eventually, they wind up having to save each other- as Abby gets sucked back inside and Connor runs to her rescue. Eventually, it's comes down to Cubix and the big monster and Cubix's only chance to win is by transformation. He changes from mode to mode until he overheats and overwhelms his opponent. Unfortunately, he overheats and overwhelms himself, too and Connor is the only one that can revive him.
