Thundercats, Volume 5: Enemy's Pride — John Layman

For years, the Thundercats have trusted their leader Lion-O to keep their people safe and to protect their adopted homeworld against a wild and ruthless menagerie of villains. But what happens when the biggest threat to the Thundercats comes from within, and the person the Thundercats turn to in a time of crisis is the person they should trust the least? Friend turns against friend in this tale of adventure, bravery and treachery.
