Jasper is a tortoiseshell-and-white tom with crazed, yellow-green eyes.
Jasper is a loner.
In his past life, he and Shiver lived in a misty glade. After their families had warred, he and her and brought them back together. He suggested to Shiver that they join SkyClan. Shiver, horrified, refused, unwilling to leave the ground where their own kin's blood had been spilled to keep the territory in the family. Jasper, in rage, attacked Shiver, who fled with her kittens to a safe hollow. Jasper swore revenge, and disappeared ever since.
Jasper attacked Flameshine and Firepelt, demanding to know where Shiver was. They fought him off, but he warned them that ThunderClan would never have any peace until she was found. Just hours later, Flameshine, Firepelt, Driftcloud, Soot, and Shiver planned an attack. Shiver dealt the killing blow, a deep wound to his neck.
Jasper appears to Firepelt twice in the ThunderClan territory, and warns him that he is looking for a host for his spirit among the ThunderClan cats. Later, he appears to Firepelt and Echowave in their dreams, and tells them he will train and guide them, and in return, they will allow him to appear to them in dreams, and host his spirit.
