Necroworld

The Necroworld is the hollow cemetery planet tended to by the legendary character known as the Necrobot. He transformed the blasted world into a beautiful garden, filled with holographic statues of every living Cybertronian, which he would switch off when the Cybertronian died. Around the bases of the statues, he planted blue flowers crafted from the residual spark energy of whoever the statue's real-life counterpart was responsible for killing. It is also where "the fortress", the Necrobot's base of operations, can be found.

From space, the planet appears to have two unnamed moons. One, much larger than the other, has its own rings.

Fiction

IDW Generation 1 continuity

The Necrobot's fortress was filled with advanced quantum technology that would let him accurately keep track of the fates of all Cybertronians. It wasn't totally foolproof. In situations where one's death couldn't be confirmed, he would record their name upon a monolith labelled "In Honor of the Disappeared."

The Decepticon Justice Division discovered the planet by complete accident. Since the Necrobot was a neutral party, they ignored him, though Agent 113 attempted to pass the place's coordinates to the Autobots by his usual method.

Years later, the crew of the Lost Light finally dug his bullet out of Swerve's shoulder. It had degraded severely by then, but the coordinates remained intact. With the location in hand, the Lost Light made a detour at the Necroworld to find out what happened to Dominus Ambus, amongst other things. The Not Knowing

The D.J.D. returned some time after that visit, collaborating with Deathsaurus in order to set a trap for the rogue Megatron and his allies. They murdered Censere (for interfering with their plan), built a base on the planet, and prepared for their quarry's arrival.

When they came, following a signal they thought would lead them toward the source of a psychological attack by the Galactic Council, they accidentally teleported inside the planet, discovering that it was in fact hollow. When they teleported again to the surface, the D.J.D. sprung their trap, forcing the group to take shelter inside the Necrobot's fortress. Deathsaurus's troops besieged the place, but retreated after a few moments with the promise to return at sunset. How Bright Their Frail Deeds The Sun in Flight

Notes

• The proper name of the Necrobot's planet of operations was not given before More than Meets the Eye #51, where it appears as a caption. The place was previously known only by its rather descriptive appellation since #44.
