Terror Twins

The Terror Twins, real names Tommy and Tuppence Terror, are two supervillains from Central City. They speak in Cockney accents, have blond hair and wear punk clothing. Tommy is three minutes older than Tuppence, but insists on referring to her as his "li'l sis", which she finds irritating. Tommy has brown eyes and Tuppence has green eyes.

They both appear to have super strength and endurance. Tuppence was able to catch a punch thrown by Superboy without taking damage, and they were each able to hit Superboy so hard that he was thrown straight through a wall. They also possess the ability to leap vast distances.

History
On July 7 they attempted to rob Gemini Gems in the Central City Mall. When a mall cop tried to intervene, they threw him off a balcony, but he was saved by Superboy. They took hostages in the food court and then fought Kid Flash and Superboy. The fight soon moved outside to the car park, and Tommy and Tuppence noticed the arrival of Flash and Superman. Deciding they weren't ready to take on members of the Justice League, they fled, and were pursued by Superman.
