Scaramouche is a mean, and rude person. In the past, he was a puppet named 'Kunikuzushi' made by the Raiden Shogun to hold the Electro gnosis, but was discarded by her. Then, he met a young boy, who was abandoned by their parents, they became a family. But then, after some time, the young boy died from his disease. Then Kunikuzushi stopped trusting people, as he became part of the Fatui, as the sixth of fatui harbingers. Anyways, he can be soft, gentle and caring, when he trusts you.
