Spike (MLP)

Spike is the main non-pony protagonist in My Little Pony: Friendship is Magic. Spike is a small purple and green dragon who is Twilight Sparkle's assistant and roommate. Spike also handles communications between Twilight and Princess Celestia, burning Twilight's written messages with his fiery breath to send them and then coughing up the scrolls Celestia sends back. He frequently displays a sardonic personality and laughs at others' misfortunes, but can be counted on to help Twilight and her friends when they need him. In some of the episodes, it is shown that Spike has a major crush on Rarity, but she is unaware of his affections until season 2. Episode 23 reveals that Twilight hatched Spike from an egg as part of an admission exam for a school of magic run by Celestia, gaining both her cutie mark and a chance to study under Celestia's direct guidance.
