Demon Ghosts



The Demon Ghosts are a quartet of spectral beings who pass by and 's campsite in the episode The Ancient One. Leonardo attacks them, even though they were just drifting through. Since he can't make contact with them, but they can with him, he assumes that he cannot win the battle. However, Ancient One convinces Leonardo to surrender, and the Demon Ghosts stop attacking, returning to their journey.

The Demon Ghosts are voiced by Sean Schemmel and Marc Thompson.
