Infraspace
| This article is about the realm between life and death. For the temporal-displacement dimension, see limbo. |
- Infraspace is an interdimensional region from the Generation 1 continuity family.

Not much is known of infraspace. In theory, it is the transitional infraspace between life and death. It is also known as limbo and has been described as "virtual nothingness". Under certain circumstances, a Transformer's consciousness can apparently exist there without a body.

According to Perceptor, Optimus Prime and Megatron passing through a space bridge together caused an "imprint" of the event to appear and follow them through a parallel course in infraspace.

Optimus Prime had received a severe beat-down from an Ore-13-powered Megatron, and was on the verge of terminal shutdown. In a desperate ploy, he transferred his higher functions into his trailer section, giving the appearance of lifelessness.
During the transfer, Prime's consciousness drifted through infraspace. While there, he felt a sinister presence that seemed to recognize and watch him.

Masterpiece Starscream Ghost Version bio
The sparks of many deceased Starscreams from all across the multiverse gathered together in Limbo, sharing the stories of their deaths with one another and formulating a plan to restore themselves to life. The scientific skills of several of the Starscreams were used to create a kind of crystal that would enable their spirits to retake physical form in the real world—but predictably enough, all the Starscreams then began fighting for a bigger share of the crystals, in hopes of achieving a more certain result. The native creatures of Limbo scattered to avoid the chaos of the battle, which ultimately concluded with all the Starscreams escaping as one, and inadvertently being fused together into a giant "ghostly" Starscream.
