Infraspace
| This article is about the realm between life and death. For the temporal-displacement dimension, see limbo. |

Little is known about the region of existence known as infraspace. It has been described as a "virtual nothingness" and denoted as the region between life and the Afterspark by Onyx Prime himself. Under certain circumstances, the consciousness of a near-death Cybertronian can apparently exist there without a body.

Notes
- The term "infraspace" was also used in Dreamwave's The Age of Wrath #3 to describe the far-less-metaphysical realm of interdimensional space. For that, see: Transwarp.
