spike (my little pony)

Spike is a young dragon and a secondary character in My Little Pony: Friendship Is Magic. He is Twilight Sparkle's assistant and also a direct means of communication with Princess Celestia. He can send letters instantly to Celestia by disintegrating them with his flame breath and receives letters from her by belching them out with his flames.

In terms of personality, he tries to act boyish and tough, but usually falls flat in his attempts. He's a bit of a glutton, he views Twilight as being like a surrogate mother to him, and he has a not-very-secret crush on Rarity.
