Spike is a baby dragon who is the deuteragonist from the My Little Pony franchise. In the fourth-generation TV series My Little Pony: Friendship is Magic, Spike is Twilight Sparkle's assistant and roommate. He is extremely loyal and efficient, but also a tad obnoxious. He has the ability to magically deliver messages to Princess Celestia with his fire breath and also has a crush on Rarity.
Spike is occasionally sarcastic and sometimes laughs at others' misfortunes, even though he usually means well. He is often defensive about his masculinity and dismissive of things he considers "girly," although his outward disdain is often a front. Though being young and often stated to only be a baby dragon, he occasionally has moments of great heroism and bravery. There are many moments in the series and the Equestria Girls films that Spike does really care for Twilight, and is supportive of her whenever she needs it.
