Transformers: Return of Generation One-Sequel to Generation One

Transformers: Return of Generation One is technically the second sequel to Generation One. Shortly after the third volume of G1 was left unfinished, Transforminator attempted to make a sequel called Generation Two. When this failed, Return of G1 was created instead as a semi-reboot. Below is a summary of each is issue.

1. 'Rise of the Terrorcons'-Scorponok, having returned after his apparent demise, sends Thunderwing and Iguanus to capture the Autobot Ironhide. They succeed in their mission, and Optimus Prime takes the Autobots to find him. Just as Scorponok begins to attack them, the Terrorcons appear and form the monstrous gestalt Abominus..
2. 'Command Performance'-Abominus defeats Scorponok and the Terrorcons join Megatron's Decepticon forces. Scorponok heads for an unknown planet and speaks with his old acquaintance, Overlord, asking him for a fragment of Unicron's power. Later, Scorponok (or Black Zarak) heads out to find the mysterious Nemesis Prime on Earth. The two engage in a duel, which shortly ends with Nemesis decapitating Scorponok. In the aftermath, a mysterious entity recovers Scorponok's remians...
3. 'Sixshot Attacks'-The Autobot Star Saber arrives on Earth and joins Optimus' team. Meanwhile, Megatron sends Sixshot and the Terrorcons to find a power converter (NOT at the Tosche Station). They start causing trouble at a city until Star Saber arrives to stop them. Just then, Sixshot is teleported away by the mysterious entity...
4. 'Galvatron'-Galvatron is recreated as a separate entity from Megatron and is sent to Earth. He encounters the Autobot Sideswipe, who is shortly captured by Thunderwing and taken to Megatron for interrogation. Suddenly, the Decepticon base is attacked by none other than...Starscream!
5. 'Betrayal'-Megatron easily beats up Starscream and attempts to summon Bludgeon, who strangely will not respond. Elsewhere, the Autobots encounter Bludgeon, who is allied with Unicron. Galvatron then arrives and attempts to destroy the Autobots, but fails. Bludgeon is soon defeated as well and is teleported to a strange chamber, where the entity Sideways has gathered the Heralds of Unicron, with Galvatron, Bludgeon, Thunderwing, and Nemesis Prime among them...
6. 'Nemesis Prime'-Autobots Trailbreaker and Hound encounter Nemesis Prime, who nearly kills them in order to reach the staff of Unicron. He then uses it to summon the Pretender Monsters, who form the gestalt Monstructor. Unicron is angered by this and sends Galvatron to retrieve the staff. The two heralds fight, which ends with Galvatron's defeat. Nemesis' victory is short-lived, as Unicron than destroys Nemesis. In the aftermath, the Autobot Wreck-Gar comes across Nemesis' remains...
7. 'The Pretender Monsters'-Astrotrain recovers Unicron's staff and brings it to Megatron. Meanwhile, Monstructor attacks a city just as the Autobot Silverbolt arrives. He begins shooting at the gestalt, which is suddenly (and randomly) destroyed by Unicron.
8. 'Endgame-Foreshadowing'-The Autobots manage to get the Ark II out of its crash site and head off Earth. Thunderwing detects the ship and breaks into it, stealing the Matrix of Leadership from Optimus Prime. Thunderwing than presents the Matrix to Unicron, who is angered that the herald did not destroy it when he had the chance. The Chaos Bringer than transforms to his gigantic robot mode and attacks Cybertron. Meanwhile, Optimus convinces Megatron that they needed to unite in order to defeat Unicron. Megatron reluctantly agrees and the two factions head out to defeat the World Devourer...
9. 'Endgame-Battle'-Optimus and Megatron head into Unicron's spark chamber, where they encounter Sideways. During their battle, Thunderwing has a slight change of heart and throws the Matrix to Optimus. While Megatron sacrifices his life to defeat Sideways, Optimus uses the Matrix to destroy Unicron. In the battle's aftermath, Nemesis, who had been rebuilt by Wreck-Gar, takes leadership over the Decepticons and forms an alliance with the Autobots.
10. 'Broken Alliance' Pt.1-Two years after Unicron's demise and the formation of the Alliance, Galvatron speaks with Nova Prime (the original Optimus) and the two of them begin to develop a plan to topple the Alliance. Meanwhile, a strange power or entity sneaks into the Alliance's base and begins to corrupt Rodimus, forcing him to abandon a (seemingly) dead Autobot. Elsewhere, Galvatron and Nova decide to form a new faction, one that would, in their eyes, bring down the Alliance. And thus, the Renegades are formed...
11. 'Broken Alliance' Pt.2-Rodimus grows to be more corrupt while under the influence of the strange entity. He then summons the Renegades to attack the Alliance, ending with Nova Prime taking command over the broken faction. He then exiles the Autobots, who go on to form the Outcasts faction. Nova's plan in bringing down the Alliance had succeeded...
12. 'The Shadows of Revenge' Pt.1-The Outcasts battle Galvatron and his Renegades on Earth. After defeating the Renegades, the Outcasts head out to end Nova Prime's tyrannical rule...
13. 'The Shadows of Revenge' Pt.2-The Outcasts return to the Alliance's base and encounter the strange entity that had been corrupting Rodimus: The Liege Maximo! The exiled Autobots trick Maximo into stepping into a bottomless pit, and the villainous being plummets to his demise. With Maximo's death, his hold over Rodimus lifts, and the fallen Autobot begins to doubt his actions. Before he can correct his mistakes, Nova Prime kills him. In the aftermath, Nova vanishes and the Alliance divides itself between Autobots and Decepticons once again.
14. 'Dead Alliance' Pt.1-Autobots Ironhide, Ratchet, and Outback travel to the planet Icono and find a mysterious being speaking with Sideways, who has apparently survived his battle with Megatron. Meanwhile, the Decepticon Cryotek sends his men to find Sideways' contact, Flamewar. On Cybertron, the mad scientist Jhiaxus is being chased by one of his own creations; the female Transformer, Arcee.
15. 'Dead Alliance' Pt.2-Ironhide and Co. arrive at a settlement on Icono and meets with its leader, Rapid Run. Cryotek than arrives and confronts Rapid Run, who sacrifices his life to destroy the Decepticon. Ironhide's group is left in confusion, and they leave the swamp-like planet, unaware that they are being followed by Flamewar...
16. 'Flamewar'-The Autobots find Flamewar on Earth and confront the female Decepticon. Unfortunately, their confrontation is left unsolved, as well as Jhiaxus' conflict with Arcee. 'Cause we're mean.
