Wally darling is a tall man with long curly natural blue hair. He is the head experimentor in Unit 6. He controls all units. The units are 1-6. He works in the last unit by choice. 

He doesn't fully approve of the experiments that are done in Unit 3. The experiments done there are highly unethical and horrible. He is a kind soul but doesnt show it.

He is 6 feet and 3 inches tall. He wears a white lab coat and black pants while in the lab, but while he's in other places he wears a black shirt.
