Spyro

"Aren't you a little feminine for a cuck?" -Spyro to Ryuko

Spyro is the eternal dragon. He first appeared at the beginning of episode 14, when Ryuko summoned him using the dragon balls in order to resurrect Utmost Wicked. It is also implied in episode 14, that Gohan and Shaggy also summoned him to restore all life on the planet after episode 13.
