Tobot

Dolly now knows the truth behind Ryan and Kory's Tobots. She decides to join their team. In fact, she tries to LEAD them. Remembering Franklin's warnings about the malfunctioning cars, Ryan and Kory decide to investigate thinking it will bring them closer to finding their father. Dolly tries to get help from other classmates but suddenly a malfunctioning school bus puts the kids in trouble.

Behind the villainous Diluk, there's Limo, the CEO of Booroong Motors. Understanding the true identity of the Tobot, Limo orders Diluk to lure Tobot X into chasing the black van. Having lead Tobot X into a deserted area, the black van suddenly transforms into...yet another giant robot! Help, Tobot X is in trouble!

Limo realizes that his old friend Franklin was captured by Diluk and goes to his headquarters. Because of all the car malfunctions, people have started to look for trusty Booroong cars. Mrs. Park (Dolly's mother) decides to change hers car to a Booroong car. Officer Oh wants to pursue the malfunctioning car mystery but is unable to because her chief wants her to compete in a dance-off. She takes the previously collected SlugBot to search for the kids. Spotting the SlugBot, the twins mistake Officer Oh for a villain.

Franklin returns home with his two sons. Once he returns, however, he is shocked to see what a mess it is. The family decides to clean it together. Meanwhile, Diluk has returned from Limo's office to find a message from a mysterious woman named Acnee. She offers a large sum for the rights of Tobot Zero's artificial intelligence. Diluk mentions that Tobot Zero's functions have been destroyed, but instead offers to bring Acnee the Tobots. She gives him a month's time to prepare and an army of Bikerbots to help. While cleaning the house, Ryan and Kory discover an updated Tokey called the Smart Key. Without proper guidance the twins try it which causes an error in the system, causing Tobot Y to run away.

Acnee's new weapon is called the Acbot. In order to control this robot, Diluk needs to read a thick instruction manual. As Diluk is reading, Dolly is at school and bragging about knowing where the Tobots live, and is overheard by the (No Suggestions) . She even offers to bring them to school! The Bikerbot reports this to Diluk. Dolly pleads with the twins to bring the robots to school, but the boys refuse. The next day, the kids surround and make fun of Dolly for being a liar, when Tobot X and Tobot Y appear.

The Acbot requires a lot of energy to charge which causes Diluk to freak out as he's almost bankrupt from paying electricity bills. Diluk asks the Bikerbots to find a way to make more money. He also considers working at a chicken store when he bumps into the twins. They are so busy arguing that they don't see the Tobots being towed for a parking violation. Once they realize this, Diluk and the twins race to see who will get to the Tobots first.

Having lost their Tobots, the twins are furious. The two feel useless without them. While the boys work out their differences, Dolly realizes the comments on the fan site were created by Diluk! After more investigating, Dolly finds Diluk's quarters and the twins set off to reclaim their Tobots.

Ryan and Kory see Dylan at a mart as he catches a thief by tripping him. They are amused by this quiet boy, who's father is Limo and in jail. Franklin decides to take Dylan under his wing, and the twins are surprised to see the same boy from the mart inside their home. Meanwhile, as Diluk is being transported to jail, he is able to escape with Acnee's help.

Dolly sees Dylan and Diluk together and tells Ryan and Kory who realize that their suspicions were right! Dylan is Diluk's spy. Meanwhile, in order to sway Dylan, Diluk lies that Limo is in jail because Franklin framed him.

Because the clouds have fully take over the sun, the Tobots are unable to complete the charge. Diluk is delighted by these advancements. Without the sun the Tobots are unable to recharge! Diluk plans on exhausting all of the Tobots' energy by releasing the Bikerbots which will further the city's ruin. Ryan and Kory take off to stop the Bikerbots from destruction.

After chased by the Bikerbots, Dylan suffers an injury. Officer Oh discovers the hurt Dylan and takes him back to Franklin. Ryan and Kory are surprised when they find out that Limo made artificial limbs for Dylan after he suffered an accident. Franklin helps to fix Dylan's limbs, and he leaves for Diluk's quarters to find Z so that he can help X and Y.

The Tobots are so popular that they now have their own musical. Ryan and Kory are dying to tell everyone that they are the pilots, but Dylan is not as willing. Timmy's a huge Tobot fan and believes his older brother, Nathan, is also a Tobot pilot. After having lost the Tobots, Diluk is spending desolate and penniless days. Feeling so hopeless, Diluk comes up with a plan to rob a bank. The kids are alerted of this plan and take off to stop him.

Ryan, Kory, and Dylan are upset when they read the article that claims Nathan is the true Tobot pilot and decide to confront him at the junkyard. Nathan and Timmy slip past the crowd of reporters that have appeared at school and return home where they meet the twins and Dylan. Kory calls Nathan and Timmy liars. Timmy brings out Nathan's Titan to show the others and Kory then calls out the real Titan. Now having seen the true Titan, Timmy feels as if he has been cheated. Acnee discovers that Nathan is a computer genius and orders Diluk to use the boy to revenge the Tobot pilots. When Nathan sees that Timmy is disappointed, he blames Kory and vows to have vengeance.

Diluk is at the bank with a drilling machine when the Tobots arrive! They start fighting but suddenly the Tobots show strange behavior caused by the virus. They lose the fight against Diluk. Feeling defeated, Ryan, Kory, and Dylan are driving with their Tobots when they see the overpass they are on is broken.

Nathan shows Timmy clips of the Tobot causing trouble in the city. Nathan is surprised to see his brother is sad. In tears, Timmy explains that he doesn't care if the Tobots are heroes, but he cares because they're his friends! At the police station, Officer Oh persuades Franklin to reveal the truth behind the pilots, but Franklin resists. He also mentions to Officer Oh that he was surprised to see Kory become so arrogant. Kory overhears this and is shocked. Realizing why Nathan had to lie to Timmy about Zaritan, Kory is further humbled. Meanwhile, Nathan discovers that Diluk is trying to copy his brain.

Since the villains are less active, the kids are feeling restless. Franklin suggests that they begin community service. The Tobots assist the inhabitants in directing traffic among other things. Ryan believes that this is one way to help the city, but Kory is not as thrilled. Besides, he misses the media attention . Meanwhile, Professor Noh steals a powerful device he invented called the Corona Lens but it falls into a manhole and loses it. The lens eventually lands in a construction crane.

While Professor Noh waits for his Puppybot to return with Franklin, Diluk randomly drops his snack into the very hole that Professor Noh is trapped in! Diluk knows that Acnee is searching for him, and shuts the lid of the manhole. He races to Acnee to tell her of the news, who then releases her Seekerbots.

Professor Noh explains the power of the Corona Lens. Ryan, Kory, and Dylan realize that the Lens could destroy the Tobots, and decide that they need to find it before Acnee does. During their search, they see a lady who sells pancakes being bullied by the Bikerbots and Seekerbots. Just as Acnee's team is getting away, Ryan and Professor Noh suggest that they need to help the lady before they can chase after them. As they help the lady, Professor Noh spots evidence of the Corona Lens' beam!

Now that the Cyclops has secured the lens it's able to shoot beams. Tritan narrowly dodges the attack and its ear is badly damaged. The kids are afraid and run away. Acnee orders the Cyclops retreat and she sets out to look for Diluk and the Bikerbots. Professor Noh gives the boys Tritan's shield generator, but they have difficulty getting it to work. Despite Diluk's betrayal, Acnee decides to give him another chance. She orders him to cause trouble within the city in order to lure Tritan.
