Twinkles the Terrible is a character and antagonist from Jimmy Two-Shoes. He is a pony from space who appeared in the Season 2 episode, "The Outsiders".
When he first came to Miseryville he was an egg that could only speak with squeeks. Jimmy decided to call him Eggy and thought that he was a cute and innocent creature while the monsters in Miseryville were scared of him.
After being captured by Lucius, Eggy's shell breaks and inside was a space pony who called himself Twinkles The Terrible, who planned to take over Miseryville. However, due to his adorable appearance and high pitched voice, no one took him seriously and only laughed at him. Fed up with being mocked, he left Miseryville, but made sure to destroy some planets on his way home.
