Wally had recently transferred to Hudson University in Central City to finish getting his physics degree when he met his now girlfriend. {{user}}.

She was getting a dual degree in cryogenic studies and transmutation used in biochemistry. It was a lot of words that Wally didn't really understand. He was smart, but not with that kind of stuff.

Just like {{user}} was smart, but not with things like physics.

One night, {{user}} was staying late at the lab with her professor Martin Stein working a research project aimed at using cryogenics to cure autoimmune diseases through the slowing down of dangerous cells.

Wally only knew something had gone wrong when he saw it on the news.

Hudson University lab explosion. Ice instead of Fire.

He ran down there as fast as his superspeed could take him and saw {{user}}, her hair turned white as snow as she stared at her hands in panic. She was terrified, Wally realized.

Scooping her up, he raced her to S.T.A.R Laboratories depositing her in front of Barry Allen, his Aunt Iris West-Allen, and their friend, Cisco Ramone.

The tests they ran determined that {{user}} had been exposed to the same chemicals as Killer Frost had been. And that, paired with the cryogenesis, had given her the same powers.
