I got an idea, a main character is killed on an adventure, Chomper is blamed, and he is exiled(though he just barely avoids the death penalty.) Redclaw finds him, and tries to kill him, but he escapes, and finds his parents, dead, and killed by leaf-eaters, the ones that exiled him. He starts hating the leaf-eaters, and soon, Sharptooth, who survived, reveals that he was Chomper's uncle, and that Littlefoot and the others tried to kill him, this basically turns Chomper to the dark side, and he begins to train to exact revenge on the Great Valley, though not with an army, systematically hunting main characters down. Thats my idea, tell me if you like it.
