Radia

Radia is the Callow Fear of radiation. It appears as a grim reaper like creature with a gasmask. It is surrounded by distortion and radiation; merely nearing it will result in death.

Radia was long thought to be the creation of the Archangel due to a shared resemblance; thus, she was classified a Fear spawn. However, she has since confirmed that she was indeed created by the Thirteen and is therefore a Callow Fear.
