The Autobots continue to defend the city while making their home in the abandoned automobile planet Sari set them up in. Optimus also encounters a Robin Hood-like thief called The Angry Archer, whom he stops from robbing an armored car. Sari accidentally uses her key to wake up Megatron, who is upset that his subordinate Starscream has betrayed him, but worse that he is only a head inside Sumdac's lab. However, he finds he is able to manipulate Sumdac's technology and uses a small pocket bot to infiltrate the Autobots new base. There he finds that Sari is introducing the Autobots to an Earth tradition called 'The Sleepover' and uses her key to scare Bumblebee. Megatron takes control of the abandoned automobile plant and uses it to attack the Autobots.

6	"Blast From the Past"	January 12, 2008
Megatron has just made himself known to Isaac Sumdac and tricks the inventor into thinking that he is an Autobot. He then helps him in reprogramming some robotic dinosaurs after Bulkhead accidentally destroys them at a robotic theme park. While Sumdac tries to rebuild them, Prowl teaches Bulkhead how to 'think and move'. Behind Isaac's back, Megatron upgrades these Dinobots Grimlock (a Tyrannosaurus), Snarl (a Triceratops) and Swoop (a Pteranodon) to become his new attack drones. But during their 'rampage', both Ratchet and Bumblebee try to use an electromagnetic attack to disable them. However, Sari's key gets pulled into the mix, which gives the Dinobots a small semblance of 'a spark'. Megatron tricks' them into attacking the Autobots, which forces the Cybertronian heroes to battle them. It is during this fight that Bulkhead proves to be exactly what the Autobots need to stop the Dinobots, his muscle more than a match for the Dinobots muscle. Sumdac thinks it would be better to dismantle the Dinobots, and Prime agrees, but Prowl, who senses a life force inside them, and Bulkhead take the Dinobots to an island in the middle of Lake Erie where they can exist peacefully.
7	"Thrill of the Hunt"	January 19, 2008
Ratchet thinks back to the time when he served in the Cybertronian War as a field medic. During the fighting, he was sent to rescue an Intelligence agent named Arcee who was injured during the fighting. The intelligence codes she possesses could turn the war in the Decepticons favor. For that reason, Megatron sends the the bounty hunter-for-hire Lockdown, to capture her, snagging Ratchet in the process. Back in the present, Lockdown has resurfaced and uses Ratchet's EMP generator to capture Optimus Prime. Recruited by Blitzwing and Lugnut to locate the Autobots who destroyed Megatron, Lockdown is revealed to be just a bounty hunter who doesn't care about the Decepticon's cause and just does it for the 'upgrades' he can get. Ratchet also reveals that the EMP generator Lockdown stole from him, which he used to repair injuries, doesn't work on the one bot it was designed for, namely him! But Ratchet also despises Lockdown for turning a medical tool into a weapon, and forcing him to use the generator to wipe out Arcee's memory so that the Decepticons wouldn't get hold of her security codes. But as a result, she wiped out every other memory she ever had, even of Ratchet and herself. Lockdown is apparently destroyed when his ship crashes into a bridge and Ratchet reveals to Prime that his encounter with Lockdown and Arcee is one of the reasons he is the way he is.
8	"Nanosec"	January 26, 2008
To obtain Destronium to help rebuild his body, Megatron bails a fleet-footed thief named Nino Sexton out of jail and gives him Isaac Sumdac's experimental super-speed suit to obtain the Destronium for him. Since the Destronium is highly unstable it needs to be transported quickly from the research lab to Megatron directly. Megatron uses Sumdac's private bank account to make Sexton do the job. Having arrested Nino Sexton before, the Autobots are shocked to learn that he now has super speed powers, which makes Bumblebee upset that Nanosec, Sexton's new name, is faster than him. Even with a pair of experimental rocket boosters created by Sumdac, Bumblebee is unable to truly catch Nanosec. However, the Autobots make two startling discoveries: 1-Nanosec's new speed suit is making him age rapidly, and 2-their constant movements are destabilizing the Destronium which will cause it to explode and take out half of Detroit. The Autobots use their combined talents to launch Bumblebee into the upper atmosphere where he hurls the Destronium away before it explodes.
9	"Along Came a Spider"	February 16, 2008
It's Halloween and Sari introduces the Autobots to Earth's costume-and-candy traditions.

When Sari takes Bumblebee and Bulkhead trick or treating, the spider-like Decepticon Blackarachnia shows up and targets Sari's key. She wants the key to get rid of her organic half that she got when she was on an organic planet infested with giant spiders. The spider's venom somehow mutated her Cybertronian systems, making her 'a freak'. After seeing how Sari's key can heal Autobots, she wants to use it to purge her organic half. However, her body can't survive without her organic half now and as a result of using the key, she nearly kills off all organic matter in the entire city (which includes herself and Sari). Optimus gets the key away from her and Blackarachnia escapes, alone once again.

Optimus decides to use Sari's key to repair their ship so that they can get off the planet and lure the Decepticons away from them.

Worse, it is the work of Prometheus Black (AKA the acid-shooting Meltdown) who has forced the Dinobots to become his watchdogs, and wants to use Sari as part of his experiments to create a transforming human. His previous experiments having failed, Meltdown thinks that a still-growing human, as opposed to an adult, will have better results, and chooses Sari because he hates Sumdac. Bulkhead is injured by Meltdown and Prowl and Fanzone team up to fight Meltdown's mutant freaks (the mammal-like one was his lawyer).
