Doctor Souichi Tomoe, also called Professor Tomoe, was a villain in Sailor Moon S and the leader of the Bureau of Bad Behavior (also known as Witches 5). Most of the time his face is shadowed whenever he has his labcoat on. He creates Daimon pods to make into Daimon Heart Snatchers. In the Sailor Stars arc, Tomoe is seen briefly enjoying life in the countryside with baby Hotaru, until Sailor Pluto shows up to take over on Hotaru's care. He was never seen again after.
