Bumblebee (Karen Beecher-Duncan) is a fictional character, existing in DC Comics' main shared universe. She is a former member of the Teen Titans and a current member of the Doom Patrol. First appearing in Teen Titans #45 (December 1976), Karen adopted the Bumblebee identity three issues later, becoming DC's first Black female superhero.

Scientist Karen Beecher was the girlfriend of Teen Titans member the Herald (a.k.a. Mal Duncan). In order to help make Herald look good in front of the team, Beecher secretly made herself a bumblebee-themed supersuit and attacked the Teen Titans. She escaped without this ruse being revealed.

When she later explained to Mal and the Titans what she had done, they were impressed enough to offer her membership, which she accepted. She and Mal subsequently moved to the new Titans West team, having relocated to San Francisco. When the Titans team dissolved for a time, Karen and Mal married and 'retired' from superheroics. Karen took a job with S.T.A.R. Labs, where she designs non-lethal weaponry.

They have returned to crime-fighting from time to time to assist the team, most notably during a short-lived revival of Titans West and the JLA/Titans event, which reunited everyone involved with the team. A fight broke out over the fate of Victor Stone, Cyborg. Bumblebee personally fought Zauriel, a member of the Justice League. Despite the assistance of the current Supergirl, Bumblebee was swiftly defeated.

Bumblebee (Karen Beecher) has not been a contender in any CBUB matches.
