Prince Tyrone (The Sleeping Princess)

Prince Tyrone is a prince played by Tyrone.

He was transformed into the evil dark dragon (and sometimes in a form of a cloud of darkness) when he unsuspectingly put on a necklace that has a dark gem that was cursed, and the gem's powers took control of his mind which makes him indirectly responsible for putting Princess Uniqua into eternal sleep. It turns out that it was his sister Princess Kathy who created the dark gem to turn him into a dragon so she could take over his kingdom. When Prince Austin tossed his sword to yank the necklace off causing it to fall the ground that shattered the gem to pieces, it not only broke the sleeping spell, but it also shattered the dark curse and restored Prince Tyrone to normal. This makes him the false antagonist of the first episode of Backyardigans x Frontyardigans, The Sleeping Princess.
