The Alicorn Amulet is a magical amulet that is featured in Transformers: The Return. According to a book that the main characters find in Twilight Sparkle's library, the Alicorn Amulet blesses the bearer with "untold powers". However, the more the bearer uses the amulet, the more it "corrupts" him or her. The book goes on to say that the amulet has an in-built magical lock that prevents any pony other than the bearer from taking it off. The Alicorn Amulet apparently has limits however, as Trixie could not use it to do certain spells like duplication, let ponies play ten instruments at once, or change a pony's gender. It's only used for good.
