A long furred large black tom with yellow eyes. Yellowtail has felt the pain of loss, having lost his mate, Rosethorn, (who he temporarily trained as an Apprentice) becoming deeply pessimistic and depressing. With this, he seems to have become indecisive. He questions things he should not and is slowly losing faith in StarClan. Before Rosethorn joined StarClan, he was happy-go-lucky with a sense of humor and an undying loyalty for his Clan.
Note: I hope for Yellowtail as a character to eventually become a more happy cat by finding love again.
