Planet Q

The world of sand known as Planet Q was home to the beings known today as Alpha Q, Scorponok and the Terrorcons. But like those beings, the world was destined for a tragic fate at the hands of the chaos-bringer, Unicron.

Energon cartoon
When Unicron attacked Planet Q, the world’s inhabitants refused to go quietly into the good night, and its armies rallied under the command of the grand chamberlain to fight back. As the battle raged, however, it soon became apparent that Unicron could not be stopped, and the chamberlain instead opted for a suicide ploy. He instructed the planet’s ruler to detonate the world’s core, hoping to take Unicron out along with Planet Q, but the ruler, paralyzed with fear, could not comply, and the chamberlain performed the task himself. Planet Q exploded as Unicron was consuming it, driving him into dormancy.

Within Unicron’s damaged frame, the spark of the planet’s ruler was able to survive, and with Unicron inactive, he was able to use the planet-eater’s powers to build himself a new body out of the "bones" of his former subjects, renaming himself "Alpha Q". Learning that, with adequate amounts of energon, he could recreate anything Unicron had absorbed, he used what small supplies he had to recreate the armies of Planet Q as the Terrorcons, with a recreation of the grand chamberlain reborn as Scorponok to lead them. Alpha Q eventually accomplished his goal in the midst of a reaction between Earth’s positive energon and Unicron’s negative energon, and Planet Q was reborn in a new sector of space containing many worlds Unicron had destroyed.

Some ten years after its recreation, the restored Planet Q was presumably one of half a dozen worlds devoured by the Unicron Singularity.
