Ralph Adebayo


 * For the other human named Ralph, see Ralph.

Ralph was a crewmember on the Moonbase. He was a geologist and acted as a general handyman.

He was working in the food stores with Ben and noticed that some of the food sacks had holes in them. When he sent Ben on an errand, he was abducted and converted by the Cybermen and used by them to work the Gravitron controls. (DW: The Moonbase)
