Dr. Maddiman

Dr. Maddiman appeared in 2013 video game called Yo-Kai Watch. Dr. Maddiman (Japanese: やぶれかぶれ院長 Yaburekabure-inchō) is a Drain-attribute Boss Yo-kai.

Dr. Maddiman is a round humanoid Yo-kai with dark pink skin that has patches of light blue on it. He has no nose, a grey tongue, five square teeth, and five messy strands of dark grey hair.

His heart is exposed and appears to be loosely stuck to his chest. It's partially blue, just like his skin, and is connected to an IV drip that is sometimes depicted as having another heart inside of it. He wears a white labcoat with a high collar, white slippers with red crosses on them, black pants, and an over-sized head mirror that seems to double as an eye, which is yellow in color.

In his left hand he has three scalpels, which he uses as weapons.

Dr. Maddiman has the ability to take a Yo-kai's heart away, causing them to become strange and attack allies. He may also take control of a Yo-kai's nerves and make them move where he wants them to while taking their heart away. Using those hearts, he is able to restore his own HP. He can also empty out a Yo-kai's Soul Meter, preventing them from using their Soultimate.

Roughly 50 years before the start of the series, Dr. Maddiman was a human doctor. His given name is not known, but his family name was "Nocturne" (Japanese: 影村 Kagemura), and he was the director of the hospital sharing that name. After his son was born, he decided that to protect his family, he would take over the world. In order to achieve this goal, he planned to create "the ultimate Yo-kai", which he would call Amatera.

During his research, he conducted many dangerous experiments on animals and humans alike, even on his own patients. Over time, he became so wrapped up in his work that he ended up neglecting his home life. Because of that, his relationship with his family slowly grew cold, and he frequently had trouble with his wife and son, the latter once extorting 30 dollars from him.

By the time he realized his mistake and tried to make it up to them, his wife had already decided to leave him.

With his family having moved to the USA, far away from him, his research was all he had left. Eventually, he did manage to create Amatera, but felt that there was no longer any purpose to it. Some time afterwards, he died.

After his death, he became a Yo-kai, but not all of his memories of his human life remained. He resumed his work on Amatera, continuing to experiment on animals, humans, and Yo-kai. At some point after becoming a Yo-kai, he started working for Chairman McKraken, aiding him in his goal to conquer both the Yo-kai World and the human world.
