Supergirl

Kara Zor-El, also known as Supergirl and Carol Danvers, is a Kryptonian superhero based in New York City and later Ysmault and National City. She is the cousin of Superman.

The Last Daughter of Krypton
Kara Zor-El's pod from Krypton crash landed in Alaska, but Superman found her shortly thereafter and found her an adoptive family in Boston. Carol Danvers grew up as the oldest child of three in a traditional Boston home, with a contractor father who believed in the merits of hard work. When he built their Cape Cod summer home, Carol insisted on working as hard as her two younger brothers, trying to make equal in her father's eyes. A voracious reader, she dreamed of becoming an astronaut and traveling to distant planets; as a teen she even hitchhiked to Cape Canaveral to view a launch there. Her father however, could not accept women as men's equals, and when financial troubles meant he could only send one child to college, he chose middle child Steve despite Carol's superior grades. Carol graduated from high school first in her class and took a sales job.

Carol's military career
She turned 18 just a few months later, and the following day she turned her back on her father and joined the Air Force, intending to be a pilot and to get a college degree via the military. Her brother Steve's death in military action would eventually draw Carol back to her family, but she still never felt truly accepted by her father. She quickly rose to the top of her Air Force class and was recruited into military intelligence (Special Operations) and trained as a spy. She accomplished many different missions and worked with other figures such as Logan (later Wolverine) and Benjamin Grimm (later the Thing), while opposing others such as Victor Creed, and Natalia Shostakova.
