Midvale is a small town in the United States.
After Kara Zor-El's pod crash-landed on Earth, she was found by her cousin, Superman, who took her to Midvale to live with Jeremiah, Eliza, and Alex Danvers. Kara was adopted by the Danvers family and grew up in Midvale.
Kara was enrolled at Midvale Junior High School along with Alex, where she was freaked out by her new world and developing powers. Later that day on Swan Beach, Kara saved a mother and her child from a crashed car.
Kara and Alex attended Midvale High School. In 2007, they investigated the death of their classmate and friend, Kenny Li. The sisters discovered that Kenny was murdered because he caught the sheriff, Ronald Collins, smuggling drugs into Midvale.
