Upon assuming command after Megatron's "death" Starscream finds that the Vehicons don't respect him as they did Megatron. In order to gain their respect, Starscream awakens the Decepticon Skyquake. Detecting an Energon signal, Optimus and Bumblebee head out to investigate, while Ratchet helps the children with their science projects (essentially doing the projects for them). Skyquake rejects Starscream as leader of the Decepticons and attacks Optimus. Bumblebee joins the battle as does Agent Fowler, who was alerted to the presence of the fighting Transformers. During the battle, Soundwave detects Megatron's Spark still online, and Starscream finds him at the remains of the Space Bridge. Despite removing the shard of Dark Energon that was keeping Megatron alive, Soundwave makes sure Starscream brings Megatron's body back for treatment. Skyquake is defeated by Bumblbee, and the two Autobots return to find that the children's science projects (which were all based on Cybertronian technology, not Earth) were not well-received (due to the damage they inflicted on the school), much to Ratchet's dismay.

Kirk Van Wormer (Co-Director)
Marsha Griffin April 16, 2011 May 1, 2011 112

She picks up Jack and races away from the ship, finding that she is unable to contact base. After dropping Jack a safe distance away, she hunts Airachnid, interrupting her foe's attack on a lone camper. They fight, but Jack's reappearance distracts Arcee long enough for Airachnid to get the upper hand and stick the Autobot to a nearby rock with webbing. Airachnid played on how Arcee seems to have a habit of losing partners. Arcee convinces Jack to run, telling him that Airachnid will kill him as she is on Earth hunting humans. Jack escapes and Airachnid tells Arcee that she will kill her-once she's killed Jack-before she starts to chase Jack. Haunted by her previous meeting with Airachnid, Arcee eventually manages to break free using her motorcycle mode. She catches up with Jack in time to save him by delivering a brutal pounding to Airachnid, who manages to flee underground after Arcee frees Jack. Arcee is left with a new respect for Jack by how he handled the situation, and is happy at the end to call him her partner.
First Appearances: Airachnid, Tailgate
Reference: This episode contains 4 or 5 possible references to the Predator franchise: Airachnid's ship entering Earth's atmosphere resembles the movie's opening scene, Airachnid coming to Earth with the sole purpose of hunting humans echoes the Predator's motive, Airachnid's trophy case of heads is similar to one seen in Predator 2, and the scene in which Jack uses a personally made flaming "arrow" to ignite the Energon resembles a tactic used by Arnold Schwarzenegger's character in the first film. The title "Predatory" may also be just as much of a reference to Predator as it is to Predacons. In addition, the musical score of Airachnid's chase scene closely resembles those in the original film.
Fact #1: The sound effects used for when Airachnid spews her webbing are the same used for Spider-Man in the 2008 The Spectacular Spider-Man, in which Josh Keaton (Jack) voiced the title character.
Fact #2: Optimus, Ratchet, Bulkhead, Miko, and Raf don't appear in this episode. Also, the other Decepticons, beside Airachnid don't appear in this episode, ether.
Fact #3: Bumblebee and Cliffjumper only appear in a flash back.
Fact #4: Starscream is absent for the second time in this episode.Note: Due to a death in her family, Susan Blu no longer voice directs this show. Instead, Jamie Simone voice directs this show from here.

When Optimus is infected with Cybonic plague, Bumblebee and Arcee GroundBridge to the Nemesis to find a cure. Bumblebee discovers Megatron has survived their last battle and is on life support in sickbay. Unable to find the cure in the Decepticons' computer, Bumblebee offers to use a Cortical Psychic Patch to enter Megatron's mind and locate it. Finding himself in a Kaonian dreamscape, Bumblebee watches Megatron killing Optimus repeatedly. Megatron realizes he cannot harm Bumblebee during one of these events and demands to know why he is intruding on his mind. Bumblebee reminds him of the space bridge explosion and implores him to give him the cure for the Cybonic plague, playing on Megatron's desire to kill Optimus for real rather than have him succumb to a virus. Megatron shows him the cure briefly, then demands Bumblebee help him out of his stasis lock. Ratchet, however, was recording what Bumblebee saw, and because they now have the cure, Arcee disconnects Bumblebee and the two Groundbridges back to base. However, Megatron's spark has left his body and escaped...into Bumblebee's head.Note: This episode ends as a cliffhanger, revealing that what happens next will be concluded in the next episode, "Out of His Head."

Bumblebee begins to experience visions of Megatron, causing him to stop dead during a basketball game with Bulkhead. After Megatron forces him to crush one of Ratchet's devices, Bumblebee tells Ratchet about the visions, and Ratchet induces a power down to give Bumblebee's mind time to recover. Bumblebee reactivates, though, under the control of Megatron and, after retrieving a piece of Dark Energon from the old battlefield seen in Darkness Rising Part 4, he bridged to the Decepticon warship which was over the Arctic. Although Ratchet and Raf try to stop him, even managing to get Bumblebee to reassert control for a few moments, Bumblebee successfully brings Megatron back online and transfers his mind back to his body. Free of Megatron's influence, Bumblebee beats a hasty retreat with Ratchet and Raf. Back at base, Ratchet checked to make sure that Bumblebee was completely free of Megatron, and the small Autobot thanked Raf for coming to help him.
Note: This following episode is the conclusion and part 2 of "Sick Mind."
Fact #1: This episode shows flashbacks of previous episodes, such as "Darkness Rising, Part 3", and "Masters and Students."
Fact #2: The Heuck Nigoghossian telescope is named after directors Vinton Heuck, and Shaunt Nigoghossian.Reference: When Starscream says "I love it when a plan comes together", it is a reference to The A-Team in which the character of Hannibal says that line as a catch phrase.

Starscream puts Dark Energon in himself, as Megatron did, and uses another piece to resurrect the Decepticon Skyquake. When the Autobots get massive Dark Energon signals, they assume it's Megatron making up for lost time, and Groundbridge to that location. The boys try to stop Miko from following and fail, the three of them ending up on the battle field. Miko wants to take a picture of a zombie, but she dropped her phone back at the base. The Autobots attack Starscream, blowing off his right arm. Skyquake is not resurrecting, so Starscream calls for an emergency Groundbridge. The Autobots spot the children nearby them, and also call for a Groundbridge. Starscream and the 3 jump in the Groundbridges at the same time, causing an explosion. Starscream returns to the Nemesis, but the children have phased to a "shadowzone" dimension where they can't be seen or heard by the Autobots. They encounter Skyquake, who is also out of phase, and a zombie. Miko, Raf, and Jack run for their lives, as Skyquake tries to kill them. The Autobots try to call the children but are unable to do so, until Jack sends a text message to Miko's cellphone. After running in circles, the kids literally run into Starscream's arm, which was sucked in with them. They shoot Skyquake with the missile attached to it, only taking his arm off. The arm comes to life and chases after them. Having realized Skyquake is functional, Starscream returns to the valley, as Ratchet sends a Groundbridge to the shadow dimension. The kids jump through the Groundbridge to let Skyquake's arm attack Starscream. The Autobots arrive a few seconds later to pick up the children. Finding himself outnumbered, again, Starscream calls for an emergency Groundbridge to the Nemesis and escapes.Note: From this episode on, Matthew Margeson composes alongside Brian Tyler.

After encountering the Autobots, operative Silas began plans for acquiring a living Transformer in order to dissect them and use their components to create such machines that would serve MECH. To that end, they ambushed a battle between Breakdown and Bulkhead where the latter was defeated in the fight. Before Breakdown could bring the killing blow, MECH neutralized him and abducted the winning Decepticon so that they could study him. Taking him to their hidden base, they switched off his pain receptors and began the process of dismantling him for parts, where they learned much from the captured Cybertronian. However, Team Prime arrived on the scene in order to deny Cybertronian technology to MECH. After some prompting from Miko, Bulkhead also goes to MECHs base, and succeeds in freeing his foe. Despite MECH's attempts at reacquiring the test subject, they are forced to retreat when Starscream arrives at the scene with several Vehicons in tow. Thus, the organization was forced to sanitize their hidden base but had managed to transfer much of the newly acquired data to a new facility despite the loss of the test subject. In his report, Silas commented that the diagnostic on Breakdown's vital components had allowed MECH to begin Project Chimera which will allow them to gain the power of living machines that would serve them.

Meanwhile, Jack gets busted by his mom while sneaking in after his curfew. That, coupled with calls from his boss at KO Burger and his teacher, prompts her to ground him and forbid him from taking Arcee out. Arcee agrees to come back and be in the garage prior to June getting home until the punishment is lifted, although the bargain will be difficult on her schedule. Despite some close calls, the ruse works. But soon MECH and Airachnaid glean info regarding Jack from Facebook, and kidnap June in the hospital parking lot. They then bait Jack and Arcee into coming to them. Arcee is captured and Airachnid plays with Jack by giving him an ultimatum - find June in 8 minutes and rescue her, or watch her being tortured. With Arcee webbed up and unconscious, Jack has no choice but to play the horrible game. Jack despite his best efforts fails to rescue his mother. Silas, however, doesn't trust Airachnid and decides to dissect Arcee here and now. Arcee regains consciousness just in time, however, and escapes, racing to help Jack, thereby revealing their secret to his mom, June. After a grueling fight, Jack, who managed to steal Silas's phone contacts Fowler, who shows up with a fleet of helicopters. Airachnaid and MECH escape though, but not before MECH witnesses Airachnid scanning and acquiring a Helicopter transformation, prompting Silas to smile and say "ingenious".

Miko and Bulkhead snuck into a monster truck rally together. A week or so later, they were reviewing the footage Miko had taken on her phone when Bulkhead was called into the field to help secure a Cybertronian data cylinder. He was, of course, followed by Miko, and during the battle she inadvertently activated the cylinder, discharging it into Bulkhead's brain. Though at first Bulkhead seemed fine, he began writing complex equations for synthetic energon, and it rapidly became clear that the cylinder's energy was overwriting his mind. While the other Autobots attempted to secure the cylinder, Miko tried to help Bulkhead retain his memories by taking him to the monster truck track. They were found there by Knock Out and Breakdown, who tried to take Bulkhead's head, but during the attempt, Miko again triggered the energy to discharge from Bulkhead into the sky. Bulkhead was left in a comatose state until Miko managed to wake him with her guitar playing.
Reference: There are several references in this episode. In the beginning of the series a monster truck announces declares the trucks are "the baddest beast machines on the planet." The design of the data cylinders are very similar to the Space Bridge pillars from Transformers: Dark of the Moon, as well as the Quintesson Journal from Transformers: Generation 1. Bulkhead's method of painting the formula is a possible reference to Transformers Animated Bulkhead. This also loosely refers to Sam's behavior in Transformers: Revenge of the Fallen after getting zapped by an AllSpark shard. Perceptor's name is also briefly mentioned in Bulkhead's rambling. Lugnut was also mentioned by Ratchet briefly, another reference to Transformers Animated.Fact: Miko is the only Autobot human ally who appeared in this episode.

Ratchet endeavored to complete the synthetic energon formula and finally seemed to succeed, running a test engine on the stuff. Wanting to do more for the Autobot cause, he injected the substance into himself as a test. Perhaps almost to his surprise, it worked. In fact, it worked so well that when Arcee got into trouble on a mission, he went out into the field himself and trashed an entire squad of Vehicons on his own. He excitedly showed the other Autobots what he had done, though Optimus was disappointed in his actions. Ratchet still felt strong, even accidentally throwing Bulkhead through a wall. He went on to inject himself with more synthetic energon, before inviting himself along on the Autobots' next mission. His vigorous interrogation of a miner and subsequent attempt to extinguish the Decepticon led to Optimus giving him a lecture. He accused Optimus of not being pro-active enough in their campaign against the Decepticons, and went off to confront Megatron on his own. Reaching the Decepticon energon mine, Ratchet made short work of Breakdown, but Megatron proved more formidable than expected, and Ratchet was seriously injured and left to Knock Out's tender mercies. After Knock Out took a sample of the synthetic energon, Ratchet managed to raise enough strength to fight back, and managed to destroy the sample. The other Autobots rescued him, though he had lost a lot of energon and had to be hooked up to a drip. Ratchet apologized for his behavior, though at least they'd gained a supply of real energon out of it. Meanwhile, back at the mine Knock Out finds dripping liquid, a sample of the synthetic energon.
Note: This episode is the continuation of the previous episode, "T.M.I."
Reference: When Ratchet blinds a Decepticon with a blow torch, this is a reference to what Mikaela Banes did to Wheelie, in Transformers: Revenge of the Fallen. This episode is somewhat similar to the Transformers: Beast Wars episode "Gorilla Warfare", where Optimus Primal is made hyper-aggressive by Scorponok's modified Cyberbee.Fact: Raf is the only human to appear in this episode.

Optimus became concerned that a prophecy detailed in the Covenant of Primus was imminent and that Megatron could regard it as his destiny. When Agent Fowler reported that the Decepticons were stealing components for a new space bridge, Optimus took a team to a military lab to stop them. Though they stopped the Vehicons from stealing the power source, Megatron himself arrived and before they could react, Bumblebee also arrived with a gravely injured Raf. While 'Bee and Arcee returned Raf to base, Optimus and Bulkhead snuck aboard the Nemesis to retrieve the power source. They located it, and Prime sent Bulkhead back to base with it, while he went in search of Megatron. He found his prey near a volcano and the ancient enemies fought. Optimus managed to beat Megatron, but as he prepared to deliver a killing blow, the volcano erupted with Dark Energon. Megatron experienced an increase in power, and turned the tide. The prophesized alignment of worlds had occurred, and Megatron had Optimus at his mercy.
First Appearance: Unicron (Cameo)
Reference: The famous Transformers line (first used in The Transformers feature film, The Transformers: The Movie) "One shall stand. One shall fall" was used in this episode. In the beginning of the episode, Optimus recites the Covenant of Primus, which first appeared in the Transformers: Beast Wars episode: "Nemesis, Part 1." Megatron refers to Optimus as "the last of the Primes," which he is also called in the same continuity video game, Transformers: War for Cybertron. This also is a term to refer to Optimus in the live-action films. Megatron used the term "rising darkness" various times in this episode, this is a reference to the Mini-Series' title "Darkness Rising".Fact: Jack's mother returns in this episode, when she is called on by Jack, to use her knowlegde of emergenacy medicine (and experince as ER nurse) help Rachet in successfully treating an injured Raf.

As Megatron is about to finish Optimus off, the other Autobots appeared through the GroundBridge to rescue Optimus. The Autobots take their battered leader back to base, where they're puzzled over the presence of Dark Energon on Earth, and slowly realize the truth. June wheels Raf to the car and explains to Optimus that the children that the children should not be worrying about their own survival; when she demands that all three of the children return with her, Miko refuses and Jack reluctantly refuses to return, angering June as she drives the car with Raf in tow. Fowler informs the Autobots of freakish global weather patterns; June and Raf get caught in the patterns along the desert highway, where an eventual tornado threatens to engulf the two, but Bumblebee arrives to save them from the car, which gets sucked into the tornado, and the three return to base.
The sequence of the tremors emanating from the Earth's core are found by Ratchet to be audibly comparable to a human heartbeat, meaning that the core of the Earth, namely the resident in it, is pumping Dark Energon, instead of magma, through its Cybertronian heart; it is also found that, while under the influence of Dark Energon, Megatron cannot stand the sound of the tremors. Prime explains the conflict between Primus and Unicron to the gathered humans and tells them he believed that Earth has formed around the slumbering form of Unicron.
Meanwhile, Megatron attempts to pledge a legendance with Unicron, but fails after Unicron senses the presence of a Prime. The Autobots set out investigating locations where earthquakes had simultaneously struck with the eruption of the volcano. However, Optimus soon found himself confronted by Unicron formed from stone. Optimus tries to plead with the Chaos Bringer for the billions of humans who dwelt on Earth, but Unicron considers them parasites and attacks Prime. Though he seems to destroy Unicron, Optimus was soon surrounded by many more duplicates of his new foe.
Fact: This is the second time that Agent Fowler and June Darby meet face-to-face.First Appearance: Unicron (fully)

In the midst of a pitched battle against Unicron, who can take many rock forms as manifestations of himself, Optimus nearly falls except for the intervention of Arcee, Bumblebee and Bulkhead. However, the group is surprised when Megatron appears to attack a giant manifestation of Unicron with a headshot. Megatron explains that, because of Unicron's stated attempt to slay Optimus, he decided to cast his lot temporarily with the Autobots in order to destroy Unicron. When the group returns to base, the humans are unpleasantly surprised by Megatron's appearance (especially after Megatron's attempt upon Bumblebee and Raf's lives). The group (along with Megatron) resolves to take the Ground Bridge to the Earth's core in order to destroy Unicron from within, and Bumblebee, Arcee, Optimus and Bulkhead reluctantly depart from the base as the humans and Ratchet look on. Before leaving, Optimus lends the Key to the Ground Bridge energy supply to Jack (in case that the Autobots do not come back alive). To Optimus, it symbolizes his perception of Jack's developing maturity throughout their time as allies.
Upon entering the heart of Unicron, the tell-tale heart pounding is heard throughout, and a giant eye moves menacingly at the top of the chamber.Fact: First time Miko sees Megatron for herself, and Megatron reveals that he never forgets a human's face when he sees Jack and Raf.

While the Autobots (with the exception of Ratchet) continue their battle at the Earth's core, while Jack, Miko and Raf learn more about Optimus's history on Cybertron as Orion Pax. As Ratchet explains the history of Optimus and Megatron, he finds Jack holding the Key to Vector Sigma in his hand. Although, Optimus told him it was the Key to the Groundbridge supply, Ratchet quickly realizes Optimus thinks he will not return. Meanwhile, the other Autobots and Megatron battle the antibodies of Unicron, where they later locate Unicron's spark chamber. While Megatron struggles to not be controlled by Unicron through Dark Energon, Optimus fires the power of the Matrix of Leadership directly into Unicron's spark. All storms, and bad weather suddenly stop on Earth. Megatron then attracts his blade, ready to slay a steaming Optimus. Right before Megatron is about finally finish him off, Optimus addresses Megatron by the name of "Megatronus", referring to Megatron's original name back on Cybertron. As the other Autobots hurry to retrieve Optimus, the two leaders hurry to the Deception base, the Nemesis. It is later revealed that Optimus didn't only lose the Wisdom of the Primes, but also his memories. The episode ends with Megatron declaring Optimus, under his original name "Orion Pax" as a Decepticon.
Fact #1: This is the season finale for the 1st season, and the episode ended with a "To be continued..." graphic, indicating that the storyline of the three-part "One Shall Rise" will continue into the beginning of Season 2.
Fact #2: This is the first time that Optimus and Megatron work in a double-team effort on camera.
Fact #3: The history between Orion Pax/Optimus Prime and Megatronus/Megatron is viewed in the novel Transformers: Exodus – The Official History of the War for Cybertron.Note: This episode aired in Asia before in the United States and Canada, in its full and original English dub.

Following the events of the "One Shall Rise" three-part episode, the Autobots attempt to recover Optimus's memories in order to regain his leadership of the Autobots. Season two will premiere on November 28, 2011.
