The latest Ultrakid recruit, eleven-year-old Heather can control not only her temper well, but also electricity. Her power was inherited from her father; both her parents were killed in a plane crash. She is best friends with Sonica.
It isn't before long that the Ultrakids discover that Heather is traitor and was secretly working for Mr. Bad Teeth. The Electric Assassin swiftly captured all the Ultrakids and OTHGG.
Fortunately, she became a good guy again at the end of Ultrakids 2.
