The Dark-Crawler's origins are unknown, but he is from an unidentified extra-dimensional realm, referred to only as the Dark-Crawler's Dark Dimension. It was composed mostly of floating rocks in a breathable atmosphere. When shattered, the rocks released blinding light. The entire realm apparently collapsed from a resonant sonic frequency released during a struggle between the Dark-Crawler and the Hulk.
