A three-video set containing
The Transformers, volumes 7 through 9. The synopsis:
Transformers Vol. 7 - The Return of Optimus Prime
The Return of Optimus Prime, Part 1
An evil scientist and his assistant decide it's time to rid Earth of Autobots and Decepticons. Their plan is to use Optimus Prime's lifeless body to lure every robot to their lab, then infect them with Sun Spores, an alien plague that instills a hatred so overwhelming that Autobots and Decepticons will want to destroy one another. It's too late to stop the madness when it's clear the Sun Spore virus is deadly to all life. The universe's only hope is to revive Optimus Prime.
The Return of Optimus Prime, Part 2
Sky Lynx returns with the only being able to repair Optimus Prime--a Quintesson. If Optimus recovers, he and his Autobots will need to find a metal alloy that will protect Prime from Sun Spores while he ventures inside a virtual world containing the wisdom of the ages. Their destination lies deep inside heavily guarded Decepticon territory. Now both Autobot and Decepticon must put aside their differences and work together if either expects to survive.
Transformers Vol. 8 - Evil Experiment
The Killing Jar
An evil Quintesson scientist assembling specimens from throughout the galaxy has decided to complete his collection. Next on his list: Ultra Magnus, Cyclonus, Wreck Gar, and Marissa. Using his superior intellect and advanced technology, he lures them aboard, and once there, runs ghastly experiments. When an unforeseen incident occurs, the Quintesson must turn to his specimens for help if any of them expect to survive.
Webworld
When Galvatron's rage is turned on his own troop, Cyclonus and his Decepticons lure Galvatron to Torkulon, a hospice planet. There he's imprisoned and forced to undergo one radical treatment after another. When all fail, only one last hope remains, a radical procedure called Maximal Intervention. Even if cured, Galvatron may end up a shell of his former self. The caretakers interface their patient directly into planet Torkulon, and what happens next could spell doom for everyone.
Transformers Vol. 9 - Grimlock the Hero
Madman's Paradise
Grimlock and the ambassador's son, Daniel, are accidentally transported to another dimension where magic rules supreme on a planet called Minonia. Saved from a barbarous band of thugs, Daniel and Grimlock dine alongside their savior in his castle and learn of the Red Wizard and his plight against Minonia's tribal bands. Little do they know their rescuer is not who he appears to be. Back on Cybertron, the Autobots must decipher some ancient hieroglyphs in order to rescue Daniel and Grimlock.
Grimlock's New Brain
Grimlock turns into a genius after shutting down a power core gone critical. That intelligence will come in handy when Galvatron gets his hands on some anti-electrons--a substance capable of scrambling Autobot circuits. The last remaining source is within Unicron's decapitated head, which is floating in space. It's a race to Unicron, where both Autobot and Decepticon alike will have more to deal with than just battling one another.
