She is a journalism student whose graduate thesis was the successful investigation of the origins of the holiday known as Miracle Monday, using a form of time travel technology that had just begun to be used by the public in her era.

She managed to convince the authorities of her time to send her to the past, at the moment when Superwoman was supposed to debut, helping Superman fight a villain called King Kosmos.

Wells soon deduced that she herself was supposed to become Superwoman, and, using some of the technology she had brought from the future which allowed her to have superpowers (including flight, teleportation, empathy, precognition, and telekinesis), she disguised herself and helped Superman defeat Kosmos.

This caused her boyfriend to lead a movement against time travel that eventually resulted in the firing of the director as well as stricter guidelines and more severe penalties for their violation.

The storyline introduces a new Kristin Wells, an older woman and Kryptonian survivor named Karsta Wor-Ul who had left the planet many years before its destruction.
