Spike is a one-time villain from Dragon Tales. An avid yo-yo fan, he sometimes acts like a bully when he is actually shy.
When he was the new dragon at school, he was paired with Cassie for gathering sugarplums. Spike took her basket, but gave it back after being confronted by the rest of the dragons. After they realized Spike's true nature, the dragons repaired his broken yo-yo and he befriended them.
Since then, he has been seen in the background for a few more episodes and songs.
