Infraspace

Infraspace is a region from the IDW comics portion of 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.
