Spike

Rainbow Dash.... I mean Spike.... is Twilight Sparkle's friend and assistant and one of the main characters of My Little Pony Friendship is Magic. He is a fire breathing pony.... I mean dragon.... and his ability to magically deliver scrolls to and from Princess Celestia with his green fire-breath is featured in most episodes. Spike has a deep crush on Rarity (but don't tell anyone; it's a secret). Spike is occasionally sarcastic and sometimes laughs at others' misfortunes; however, he is very helpful and supportive towards Twilight. He is often defensive about his masculinity and dismissive of things he considers "girly", although his outward disdain is often a front. All in all he's a pretty cool guy and he's got sag to spare.
