Tsiehshi

It's like a slightly more hospitable version of Australia.

Tsiehshi is a barren desert world, largely devoid of life and scorched by the heat of two suns. Its most distinctive feature is also its most dangerous—the Ore-8 crystals that cover the planet are highly explosive and emit dangerous, mind-scrambling radiation.

Fiction

2005 IDW continuity

Following his murder of Solus Prime, Megatronus fled across the galaxy and went into hiding on Tsiehshi, subsisting off the energy of electrochemical flowers that grew there. In time, he was tracked down by Prima and Onyx Prime, and in the conflict that followed, Megatronus was able to seize Prima's Star Saber and bisect him with it. The victorious Megatronus was then slain by Onyx, who was, in actuality, a disguised time-displaced Shockwave from ten million years in the future. As "Onyx", Shockwave went on to feed Alpha Trion a falsified account of the battle on Tsiehshi that claimed Prima and Megatronus had killed each other, which would become the version of events publicly recorded in Cybertron's history. The First Who Was Named

Many millennia after "Onyx" departed Cybertron, the younger Shockwave selected Tsiehshi as one the worlds for his Regenesis project, firing a missile loaded with modified energon ore at it, in hopes the ore would develop into a new source of fuel that could replace the rapidly-dwindling reserves of his war-torn homeworld. Over time, the ore developed into an expansive system of "crystals of pure destruction" that covered the planet. Shockwaves

Unknown years later, the Autobots Kup and Outback crash-landed on Tsiehshi. Outback eventually died in an accident and Kup was driven insane by the Ore-8 radiation. The other Autobots subsequently found their lost comrade and sent several rescue parties, only to have them be killed by a paranoid Kup. Eventually, Trailbreaker, with his special skills, was brought in to recover Kup. However, the scars of Kup's experience on the planet remained even after his departure. Spotlight: Kup
