Bumblebee, real name Karen Beecher, is a member of the Team. She is a former student of Happy Harbor High School, where she was a classmate of Superboy and Miss Martian. She is romantically involved with Mal Duncan.
Bumblebee derives her powers from her suit, which was created with help from the Atom.
- Flight: Bumblebee can fly with four wings, resembling an insect's forewings and hindwings, that extend from the back of her costume. These wings only work when she shrinks herself.
- Holographic computer: Bumblebee has a holographic computer similar to that used by Batman's protégés built into the gloves of her suit.
- Size alteration: Bumblebee has the ability to shrink herself. Though hypothetically, it can range in size, Atom has included safety locks so that she can only change into one size.
- Stings: Bumblebee can shoot small blasts from the palms of her gloves.
