A Gama-Sennin is a Light Fae toad species.
Tyler is a Gama-Sennin and used his secretions to keep his adoptive human father, Mike, from getting beaten in Bare Knuckle Cage Fighting. He is unaware of the full extent of his true nature and, unfortunately, Mike's body is not designed to handle the constant infusions of such Fae power, as his son's efforts were verging on causing his death.
