Tobot

Limo gives Tobot Z an exciting new upgrade called "Adventure Z." However, before Dylan gets a chance to test out Z's new moves, the boys are called out on an emergency mission to Daedo City.

Limo initially turns down Angela's offer to come work with her, but when she tells him it's for a charity project his resolution wavers. To really persuade him, Angela shows Limo the towtruck she's been working on, and reveals it's made with parts of Tobot Zero, one of Limo's old creations.

Everyone is visiting Dylan at the hospital while his leg is healing-- except for Limo, who unbeknownst to the team, is secretly working on Zero. Diluk is also keeping a secret of his own, pretending to be suffering from his extreme diet, and then sneaking off to gobble up all kinds of sweets.

The police discover that it's one specific tow truck that's dispensing SlugBots all throughout the city, and decide to track down the vehicle's owner. Back at the hospital, Dylan is brought up to speed on the dangerous consequences of the racing game he was given.

Angela reminds Diluk that they used to work together at Boorong Motors, but he struggles to recall her. Once he does remember however, he is threatened by her arrival, seeing her as competition for the position of Chairman. Back at the hospital, the kids attempt to hide Limo's status as a public enemy from Dylan.

Dylan arrives at Angela's boxing club with the intention of investigating what her connection is to Limo. Dylan unknowingly makes contact with Angela, but she cleverly dismisses him.

Dylan tries to uncover the mystery of the black key left to him by his father. He paces through his home, pushing the button on the key in an attempt to discover what it controls. As he opens his front door he encounters Tobot Zero, who's been waiting for him outside.

Ryan and Kory receive a call from Dolly, who's asking for backup at the Boorong Motors factory. Wondering if they were wrong all along about Limo, they try to leave for the factory but are held up by another onslaught of renegade cars.

Diluk demands to know why Mr. Towers thinks he can't be Chairman. Mr. Towers introduces his own villain disciple; Mr. Majeeko, and explains that this suave magician is clearly better suited to the task. Mr. Holmes and Mr. Towers agree to a competition to determine which of the villains will earn the top position of Chairman.

Tobot X prepares himself for his new upgrade. He reminisces about his younger days as a little mind core and he wonders whether he'll like his upgraded version. Tobot Y tries to tell X he's being dramatic, to no avail.

Limo, Dr. Noh and Franklin remain stumped over Tobot X's programming bug. Despite their best efforts they still haven't been able to identify the problem.

Team Tobot waits anxiously for Diluk's next phone call. Nathan secretly switches his phone case with Kory's and disappears. Outside his home, his phone finally rings. It's Diluk, calling to set up a time and location for the exchange.

Devastated over Y's defeat, the pilots discuss their bleak situation. Dr. Noh arrives with some much needed good news; Tobot X has finally been repaired! Spirits lifted, the pilots begin plotting Timmy and W's rescue.

With the rest of the Tobot Team looking on in horror, Kory barely lands Y safely. The team rushes toward Tobot Y, open the cockpit and are irritated to discover that Kory was just playing a prank on everyone. Before they have a chance to scold him, Diluk calls yet again.

Angela's robots are fended off by the arrival of the rest of the Tobots. News spreads between the pilots and the villains that Timmy's made his way to Daedo World, the amusement park.

Kory and Ryan are interested in a popular new video game based on the Tobots. Kory wants to pick up a copy but Ryan advises against it, reasoning that it may reveal their true identities if the actual Tobot pilots play a game based on them.

Diluk is disguised as a student and waits outside the school yet again. When Ryan emerges, he tails him around town, standing by until Ryan and his friend part ways. Diluk reports back to Angela that Ryan is alone and she sends some more old robots to cause trouble ahead of Ryan's path.

Dylan and Dolly, like the twins before them, use the game skills in real life. The results are immediate and successful, further convincing the pilots that these moves are more powerful than the ones they've been using in the past.

Franklin, Limo and Dr. Noh board a ferry they believe is meant to take them to the tech conference.

Mr. Holmes tells Diluk of his plans to overthrow the current Mayor of Daedo City, and to replace him with Diluk. Angela receives news that the Tobot pilots have removed the mind cores from their Tobots.

With the Tobots gone, the pilots finally come to their senses and realize that their addiction was largely caused by the embedded sound waves in the game.

Officer Oh warns Limo that the train has changed directions and is making it's way back, full steam. Limo hurries to place the Mind Cores back in the Tobots, but he's working in the dark. Officer Oh panics as she witnesses the train transform into a terrifying villainous robot.
