Iron Will is a minotaur character from My Little Pony: Friendship is Magic, known as a self-help guru who teaches ponies to stand up for themselves through loud, confident assertiveness training. His rhyming introduction, pairing his name with his trade of training ponies, became a memorable catchphrase for fans because it sums up his whole personality in one boastful line. Shared widely as a short meme clip, it is now reused by creators who want an instant, theatrical introduction for confident, stubborn, or hilariously self-assured moments.
