Powers. No innate metahuman powers; uses a self-built bumblebee-themed exo-suit granting flight (insectoid wings), size manipulation/shrinking (in later/post-Crisis depictions), and energy "stingers"/electrical blasts.
Origin
Karen Beecher, a brilliant scientist and girlfriend of Titan member Mal Duncan, designed and built her own high-tech bumblebee suit — granting her flight, shrinking ability, and a powerful sonic sting — and used it to stage a bold solo operation intended to help Mal earn greater respect among his teammates, inadvertently proving herself worthy of joining the team in the process.
