Bombshell is a fictional character, a comic book superhero published by DC Comics. She first appeared in Teen Titans vol. 3, #38, and was created by Geoff Johns and Tony Daniel.

First mentioned in Teen Titans vol. 3, #38, she was a member of the Teen Titans during the one year gap after Infinite Crisis. She has similar powers to Captain Atom as she underwent the same alien metal skin experiment that Nathaniel Adam did. Prior to this, she was recruited into a rogue military black ops unit when she was arrested for assault and battery and faced jail time. This rogue group made a habit of accepting dubious freelance contracts in addition to their own projects. Using the same extraterrestrial metal that comprises Captain Atom's skin, the group grafted the metal onto Amy's human skin.

In Teen Titans vol.3, #40, Bombshell is revealed to be a traitor to the Titans, as she threatens to kill Raven, and attacks several members of the team to get a disc that contains the essence of the deceased Titan Jericho, but is stopped by Ravager. At the end of issue #41, the Titans beat her by shattering her metal skin. Since it is this metal coating that provides her powers she temporarily lost her abilities.

In Teen Titans vol.3, #43, Cyborg and Miss Martian visit a depowered Bombshell in jail. After refusing to tell them who she worked for, Miss Martian proceeds to probe her mind. In doing so she discovers the existence of Titans East, and that Bombshell is a member. Before any additional information is discovered, Batgirl and Risk break into the cell — but not to save their former teammate. Instead, Batgirl slices Bombshell's throat with a batarang.

Bombshell has not been a contender in any CBUB matches.
