Iron Planet

Iron Planet is a planet, presumably made of iron, in the Energon portion of the Unicron Trilogy continuity family.

Easy come.

Bleak and barren, Iron Planet is one of many planets consumed by Unicron over the course of its never-ending quest for sustenance. It contains a surprisingly large amount of energon, and so quickly becomes a target for the Decepticons.

Fiction

Plot points derived exclusively from the Super Link version of the Energon cartoon are in italics.

Iron Planet was one of the first planets restored by Alpha Quintesson. Shockblast, injured from his attempt to overthrow Megatron Ripped Up Space, awoke on a region of the planet. Since Iron Planet was still undergoing the final stages of reformation, rocky spires and outcroppings frequently sprouted with great speed, driving the Decepticon to paranoia.

Easy go.

Shockblast was chained up by the Autobots in a conveniently O-shaped rock formation Protection. The other Decepticons made several unsuccessful attempts to raid the planet for energon Jungle Planet, and it was in a valley on Iron Planet that Megatron forcibly inducted Inferno into his ranks Imprisoned Inferno.

The planet was eventually destroyed by a brainwashed Scorponok, who had drained it of all its energon while the Autobots were occupied on Jungle Planet Bulkhead. The debris left by the destruction played host to Inferno's final effort to overthrow Megatron's programming and subsequent death Farewell Inferno.
