Bonetail

In Paper Mario: The Thousand Year Door, Bonetail is a large Dragon, living at the bottom of the Pit of 100 Trials.

He is the oldest member of the "tail" family, older than both Gloomtail and Hooktail. As his name implies, he is merely a skeleton of a Dragon, implying that he has been living far longer than the other members of the family. He was once a minion of Shadow Queen, but has apparently stopped serving her. Any actions outside of the Pit of 100 Trials, if any, are unknown.
