Megatron Returns

Megatron Returns is a book that ties into Transformers: Prime.

Synopsis
Cliffjumper detects an energon deposit, but once there he is jumped by Decepticons and dragged before Starscream who kills him. The Autobots arrive at the site soon after and find Cliffjumper's horn. After they eulogise him, Arcee races off and encounters two Decepticons, inadvertently involving Jack Darby. Once Bumblebee joins in, the fight moves to a location near Jasper where they find Raf Esquivel, and the two young humans are exposed to their first giant robot fight. Arcee and Bumblebee are later sent to pick up the pair and end up bringing them and Miko Nakadai back to the Autobot base where Optimus Prime briefs them.

Meanwhile, Megatron returns through the Decepticon spacebridge with a quantity of Dark Energon, which he uses to revive Cliffjumper as a Terrorcon. The Autobot's signal is detected by the Autobots who, after a visit from Agent Fowler, bridge to the energon mine to try to rescue their comrade. They're unsuccessful and Starscream destroys the mine, but the four Autobots return to base where Arcee, Bumblebee and Bulkhead are paired up with their new human friends. Megatron infuses himself with Dark Energon.

After Ratchet has an encounter with a reanimated tool, Optimus realizes the Decepticon plan and takes Ratchet to an ancient battlefield. As Arcee and Bumblebee go out on patrol, Bulkhead is left at base with the kids and has to contend with a visit from Fowler. Fowler leaves the base, only to be attacked and captured by Laserbeak. Bulkhead is forced to start a rescue by GroundBridging to where the Nemesis is parked, but is followed by the kids. Meanwhile, Optimus and Ratchet encounter Megatron, who raises an army of Terrorcons to fight the pair.

Bulkhead infiltrates the Decepticon warship with Miko in tow, and is soon joined by Arcee and Bumblebee. The trio deposit the kids in an empty room while they rescue Fowler from Starscream's clutches, and Miko is able to take a photo of some interesting data Raf finds. Jack, having had enough of the whole affair opts to return home, and the Autobots realize that the spacebridge calculations the kids found means Megatron intends to raise Cybertron's dead as an army of Terrorcons.

After Arcee talks Jack into returning, the Autobots GroundBridge up to the Spacebridge. When it's realized that the Decepticons need outside help to target Cybertron, Raf suggests they're using the Very Large Array in New Mexico. The three kids bridge to the array to try to prevent Soundwave from using it, but fail, and Megatron sends the Dark Energon through the Spacebridge to Cybertron. With the help of Spacebridge plans downloaded by Raf, Ratchet instructs the other Autobots in sabotaging the Spacebridge, causing it to explode and apparently taking Megatron with it. The Autobots return to Earth where they are reunited with their new friends.

Differences with the episodes
As the book is fitting five episodes into 136 pages, there's a substantial amount of cutting. Many of the lines are also altered in wording, though usually not meaning.
 * Arcee asking if Cliffjumper needs backup is gone, as is the cannon on the Nemesis firing at Cliffjumper.
 * The scene with Arcee contacting Optimus Prime and the Autobots being alerted to trouble is transplanted onto the start of the scene where they arrive at the battle site.
 * Likewise the scene with Soundwave relaying Arcee's transmission to Starscream is brought forward to just after Cliffjumper's termination.
 * The exchange between Ratchet and Optimus at the end of Cliff's funeral is missing.
 * Arcee comments on the Jerky Teen's driving.
 * The whole encounter with Sierra is missing.
 * So is Raf calling his mom.
 * When Bumblebee and Arcee return to base, their conversation with Prime is trimmed down to just the last line.
 * Jack's Fight Club reference is missing.
 * The pre-credits teaser for episode 2 is combined with the later scene in which Cliffjumper is zombified.
 * Ratchet's protests about letting the kids stay are gone.
 * All mentions of Unicron have been excised.
 * Megatron specifically calls Cliffjumper a Terrorcon.
 * Ratchet notes that Cliffjumper's signal is in "negative polarity".
 * The fight in the mine is cut down to a few paragraphs, and the scenes with Ratchet and the kids back at base skipped entirely.
 * The scene with Optimus pairing Autobots with kids is truncated down to him announcing that the Autobots would be keeping watch over them.
 * The next morning scene with Jack and Arcee is gone.
 * The scenes with Ratchet's tool coming to life and Megatron imbuing himself with Dark Energon are swapped in order.
 * The scenes of the Autobots returning to base with the kids are skipped.
 * The scene with Megatron's imbuing with Dark Energon is moved to between Arcee and Bumblebee leaving the base, and Miko trying to get the others interested in making music. The latter sequence is also cut down substantially.
 * All of the scenes with Ratchet and Optimus fighting the Terrorcons are combined into two sequences, placed after Jack and Raf arrive at the Nemesis, and after the bots meet up on the Nemesis respectively. The place where the battle with the Terrorcons takes place is dubbed the Lost Valley (other tie-in media treated this area as the Grand Canyon).
 * Laserbeak is identified as such.
 * The first scene in which Starscream uses the prod on Fowler is missing.
 * Bulkhead asks if Arcee got back to base before he leaves on his solo attempt to attack the Nemesis.
 * Starscream is keeping Fowler in a laboratory rather than the brig.
 * The second scene with Starscream interrogating Fowler is combined with the later one in which the rescue takes place.
 * The Autobot/Vehicon fight in the corridor is trimmed out altogether.
 * Jack and Miko's argument is cut down.
 * Raf is frozen in fear rather than going back for his bag.
 * Most of Jack and Miko's argument when they get back to base is removed as well.
 * The fictional Giant Sized Array in Texas mentioned in the episode is replaced with the real-life Very Large Array based in New Mexico.
 * The Autobot/Vehicon fight on the spacebridge is covered in just a few paragraphs. The cutaways to the Autobots and Decepticons in space while Raf and Soundwave mess with the dishes are left out.
 * The scene where the kids see Soundwave leaving is missed out.
 * As the Autobots prepare to destroy the spacebridge, Optimus reminds them of the siege at Mila Nellus.
