Trama

Sari Sumdac is coping with the newly discovered fact that she's a robot. Meanwhile, the Autobots on Earth are trying to figure out a way to warn the Autobots on Cybertron about the spy working for Megatron. Later, Megatron and Starscream find Omega Supreme and set a devastating plan in motion.

Space Bridge Outpost 687030 on an unknown planetoid. The Space Bridge is on one end, an Autobot base is on the other. Ironhide, Hotshot & Brawn were under assault by Cyclonus, Strika & Oil Slick. Hotshot tried to repel Strika's missile attack, but received damage to his leg. Red Alert provided medical assistance to HotShot, but Spittor grabbed her with his tongue tendrils and swallowed her. The Decepticon then spat her back out, covered in explosive orange goo. She became a living bomb, aimed right at Brawn and Ironhide. Rodimus appeared, and contacted Elite Guard command, asking for assistance.

On the Autobot Flagship, Jazz received Rodimus' distress call, but the Elite Guard didn't have the resources to spare, as Decepticon attacks at all outer Space Bridge outposts had them tied up. Ultra Magnus hoped to keep the Decepticons from transwarping an invasion force onto Cybertron.

From Cybertron, Longarm Prime reported that the Space Bridge Nexus was fully guarded. After Ultra Magnus signed off, Longarm transformed into his true form: the Decepticon Shockwave.

Back on the Space Bridge planetoid, Rodimus rallied Brawn and Ironhide against Strika and her crew. Oil Slick and Cyclonus took Ironhide and Brawn out, while Rodimus repelled Strika and Spittor. Rodimus left Spittor pinned to the ground by his tongues. The battle seemed to be turning around, until Blackout arrived and blasted the whole planetoid with his EMP. Strika scolded Blackout for taking the Space Bridge offline, but Blackout simply apologized and reactivated it with a stomp. Strika ordered Cyclonus and Oil Slick to free Spittor and secure the perimeter, but the were interrupted by Rodimus. Rodimus challeged the Decepticons, but Oil Slick mocked him and threw a vial of green liquid at Rodimus, causing him to collapse and he screamed "Cosmic Rust!" Strika then reported their success to Shockwave. The Decepticon infiltrator informed her that her group, "Team Chaar", would have to wait for Megatron to Transwarp to Cybertron before the could invade.

Elsewhere, in the depths of space, Starscream (merely a head) and Megatron bickered, while Starscream tried to free Megatron from his stasis cuffs. It didn't seem to go well for them, until Starscream became angry, transmuting a gun from his mouth and blasted the stasis cuffs off of Megatron. Before they could celebrate, Omega Supreme warped in behind him. Starscream panicked, but Megatron calmed him by noting that the gigantic Autobot was offline.

Meanwhile, on Earth, Sari and Isaac Sumdac rode back home inside of Optimus Prime. Sari derided Sumdac for not telling her about her robotic origins. Sumdac apologized for not telling her, but he wasn't sure where she came from. He told her that he found a small liquid metal form, and that Sari appeared after he touched it. They arrived back to Sumdac tower to find Isaac's lab trashed and inhabited by Porter C. Powell and Henry Masterson. Sumdac ordered them off the property, after Masterson threatened them about the loss of his Headmaster unit. When they refused to leave Sari manifested energy blasters from her hands and blasted them into the elevator. Sari epressed her anger at Sumdac's secrecy, and chose to return with Optimus, to the Autobot's Manufacturing Plant base.

Once there, the Autobots attempted to build a communicator, to warn the Elite guard that Longarm is really a Decepticon spy. Bumblebee chided that if they still had a ship, communications wouldn't be a problem. The mention of the loss of their ship triggered a flashback in Ratchet. In the flashback, Ratchet was with Ultra Magnus, who took him to the mind-erased Arcee, in hopes of retrieving the lost access codes she had carried. After the flashback, the Autobots decided to salvage the ruined Space bridge that Megatron forced Bulkhead to build, while Ratchet examined Sari's circuitry. Ratchet discovered that Sari is organic, but with inlaid Cybertronian circuits. Sari feared that she was made from parts of Megatron.

In space, Blurr Skywarp and Thundercracker laid trapped in a lump of Mixmaster's cement goo on a barren asteroid. Skywarp complained while Blurr stated that concentrated sonic pulses at alternating frequencies could free them. Thundercracker claimed the idea as his own and implemented the measure, destroying the cement. He then proceeded to attack Blurr, but Blurr was too fast, and even used Thundercracker's own momentum to propel himself into space. Blurr tried to contact Cybertron, to no avail.

On Earth, Masterson recovered his Headmaster Unit, as well as Starscream's headless body, and vowed revenge.

In deep space, Megatron forced his way into Omega Supreme, setting off the intruder alert, which in turn reactivated the giant Autobot. Before Omega could terminate the Decepticon leader, Megatron convinced him that he came to turn himself in, and that he deserved a trial on Cybertron. Omega Supreme agreed to take him into custody, after he removed Megatron weapons. The Autobot Guardian also captured Starscream's head. Megatron told Omega to find a Space Bridge and take him back to Cybertron, to which Omega Suprme stated that a Space Bridge was unnecessary. Omega then transformed into his spacecraft mode and activated his transwarp engine. They then teleported away in a huge glowing blue sphere.

On the destroyed Decepticon base on Earth, Bulkhead and Bumblebee searched for salvageable Space Bridge parts. Bulkhead told Bumblebee that he needed a Plasma Dynamic Thruster (it's the thing that generates the transwarp field that teleports you across the galaxy). Bumblebee popped up with another part, a Retrieval Beacon Generator (necessary for transwarp navigation). As he dug, Bumblebee found the Plasma Dynamic Thruster, and accidentally activated it, disappearing in a blue sphere. As Bulkhead seached for his missing friend, the Headmaster attacked, in Starscream's body, incapacitating Bulkhead.

Back at Sumdac tower, Prowl surveilled Isaac Sumdac. accessing his files and scanning the scientist. The Autobot ninja searched for clues to Sari's origin, while back at the Autobot Plant, Ratchet continued to examine Sari. While he discussed a deeper exploration of Sari's circuitry, Ratchet had another flashback. This time the medic recalled working on Arcee, with Highbrow, Mainframe and Ultra Magnus present, when a pulse on information beamed from the female Autobot's head into Ratchet's. Ratchet reported the beam, though he didn't know what it was. Highbrow knew, and ordered Ratchet to come with him. The three Autobots left and arrived the location of "Project Omega". Ratchet looked around to see various Autobots (including Wheeljack and Perceptor, as well as possibly Ironhide and Wideload) building the gigantic form of Omega Supreme (It also appeared that a second Guardian was being built to the far left of Omega Supreme). Ratchet woke from the flashback, and decided to go see what was taking Bumblebee and Bulkhead so long. Optimus offered to catch up with him after he took care of something. Optimus Prime then surreptitiously contacted Sumdac, as the Autobot offered to take Sari to Burger Bot to eat. The call was intercepted by Masterson, who had Sumdac's office bugged. As Optimus tried to patch things up between Sari and Sumdac, the Headmaster arrived and menaced Optimus, Sari and Isaac.
