Sharon Carter

a.k.a. Agent 13

Mini-biography:[]

An agent of SHIELD and a longtime love interest of Captain America (Steve Rogers), Sharon Carter's first "death" occurred after she was brainwashed by the villainous Dr. Faustus and forced to join Faustus' white-supremacist group The National Force. When cornered by police, a group of National Force members committed mass suicide by activating incendiary devices in their uniforms. Captain America witnessed the incineration, but had not seen beforehand whether Sharon had been among them. For several issues, Captain America remained uncertain whether Sharon was alive or dead, until news reporter Katie Burns showed him video footage of Sharon's demise.

Years later, Sharon's "death" was revealed to have been a hoax, the video having been staged to convince Steve that she was dead. In fact, she had escaped Faustus' mind-control, and was on a deep-cover mission for SHIELD. She was revealed to be alive in Captain America #445, and she eventually resumed her relationship with Captain America.

She apparently died once again while she and Steve were battling Arnim Zola in the other-dimensional world of Dimension Z. As Sharon, Cap, and Zola's daughter Jet Black prepared to escape to Earth and activate a detonator to destroy Zola's fortress on the way out, they were attacked by Zola (manifesting in a new, gigantic body). Sharon sacrificed herself by attacking Zola and triggering the detonator, causing a huge explosion that seemingly destroyed both Zola and herself.

It was later revealed that she had in fact survived the explosion, and she returned to Earth after Captain America and The Falcon discovered her alive in Dimension X (albeit much older due to the time difference between the dimensions).
