Some TMNT stuff really isn't for little kids.

The Great Turtle is the father of all turtles. His arch-nemesis is the Adversary, who is a giant rat.


Once a giant, intelligent turtle from prehistoric times, one whose eggs were eaten by the emerging mammalian rats. The rats were the children of the Adversary, who would feed off the Great Turtle’s subsequent sorrow, even beyond the grave. When Donatello explored the wilderness of Northampton, the Great Turtle briefly met him, leading Donatello to convince his brothers to return with him to it. Their journey into the woods beginning as a merely free spirited journey, soon Donatello began to hear the voice of the Great Turtle, telling him to stand against the Adversary, the enemy of all reptiles. Donatello declared himself the "Shaman" to oppose the Adversary, though upon being badly beaten in combat by him, realized the Shaman was Leonardo. Leonardo climbed to the place where he waged his final battle with the Adversary and, guided by the Great Turtle, emerged triumphant. The fossil Mesozoic eggs scattered across the world broke apart as fetal reptile souls, the Great Turtle’s included, were freed by the death of the Adversary (Turtle Soup (vol. 2) #1, TMNT Vol. 1, #37).
