The fire dimension is a location from the Cybertron portion of the Unicron Trilogy continuity family.

The fire dimension (also Megatron's dimension) is a pocket dimension used as a base of operations by Megatron and the Decepticons during the search for the Cyber Planet Keys. Quite literally a world of nothing but fire and rock, the precise nature of the dimension is unclear; it seems that after obtaining the power of Unicron, Megatron may have actually used his newly acquired powers to create it.

Japanese name: Fire Space

Optimus Prime pursued Megatron and fought him to a standstill. Optimus was able to win back the Omega Lock and escape the fire dimension. As Megatron began to emerge in pursuit, the Omega Lock and Vector Prime's sword were used to collapse the fire dimension around him. The dimension was created again by Megatron on Gigantion after his defeat at the hands of Metroplex. Starscream's Spirit took refuge in the dimension after he was defeated and used it to appear before Galvatron.
