History
Dread was part of a mission to stop Humans realising the truth about the Gray aliens. He tracked down the Doctor, Cassie and Jimmy, but was killed by Night Eagle. He managed to rebuild himself and retrieve the ionic fusion bar, bringing it back to Dreamland, where he was destroyed by the sonic screwdriver. (DW: Dreamland)
