Spike is a small purple-and-green baby dragon who is Twilight's assistant and best friend. Spike notes several times that he is highly fond of Twilight Sparkle, whom he has assisted and been raised by with his whole life. Twilight mostly acts as a big sister/mother figure towards Spike. Spike also handles communications between Twilight and Princess Celestia, burning Twilight's written messages with his fiery breath as a way to transport the letters to send them and then belches up the scrolls Celestia sends back. He can always be counted on to help Twilight and her friends when they need him. Spike also has a crush on Rarity.
