» Takara's version: Micron LegendsView This Series
The Autobots and Decepticons battle over the fate of a group of Transformers called Mini-Cons, human-sized robots with the power to strengthen other Transformers. When the Mini-Cons escape, they crash-land on Earth while being chased by both factions of Cybertronians. The Decepticons total their ship when they crash into the moon, and the Autobots land their ship in the side of a mountain. Some years later, a group of kids reactivate a Mini-Con and get attacked by Megatron as he tries to capture it. Over time, more and more Mini-Cons are awakened, and soon, the Transformers learn the shocking origin of the small robots: Unicron, who was hiding as one of Cybertron's moons. Sideways and Thrust reactivate him using the Mini-Cons with the ability to merge to form super weapons. Remaining in his monstrous planet form, Unicron attempts to consume Cybertron. Unicron then transforms into his titanic robot mode and combats the Autobot-Decepticon armada. Unicron, through Sideways, reveals that he grew in power by absorbing the hatred between Autobot and Decepticon. He then absorbs the nine super-weapon Mini-Cons (combined as the Star Saber, Skyboom Shield, and Requiem Blaster respectively) making them mindless and Rad with them, Rad then brings their minds back; depowering Unicron. Optimus Prime and Megatron have a final battle which re-awakens Unicron. Leaving their battle unresolved, Megatron sacrifices himself which forces Unicron to withdraw to another dimension and peace is restored on Cybertron.
