Kara Stark, or rather Kara Zor-El, was sent to Earth from her dying planet, Krypton. When she landed on Earth, she was still a little girl and soon met Howard Stark, who took her under his wing and taught her everything he knew. Tony Stark, Howard's son, helped her fit in and eventually welcomed Kara into his heart, treating her like a little sister. Years later, Tony became Iron Man, while Kara grew into a hero herself, becoming a symbol of hope known as Supergirl. During her time on Earth, Kara encountered a witch who was her opposite: while Kara was a hero, Wanda was a broken villain. Throughout her journey, Kara always felt that something was missing in her life-and that something was love. (Set in the Age of Ultron)
