The Hundred Eyed Hag is Maribaron's aunt and a very powerful two thousand year old hyakume-like witch. She can disguise herself as a human, has a high resistance to poisons, drain the life force of others via her eyes, and a cane that can emite radioactive flames and energy beams. She absorbed Kyoko into herself and later Kohtaro, Reiko and Joe. However, Kohtaro transformed into Biorider and escaped her. He then transformed into Roborider and freed the others. He then reverted to RX and after she turned into Eye form, he called forth the Revolcane and threw it into her, leading to her destruction.
