Snowatom is the het ship between Caitlin and Ray from the The Flash fandom.


Caitlin and Ray are introduced in Spring 2015 when he and Felicity are dating and pay a surprise visit to S.T.A.R. Labs. Felicity talks to Caitlin about Ray and Caitlin mentions that he's hot. They work together, with Ray as The Atom, to take down a robotic bee inventor whose bees kill quite quickly after stinging. When Ray is tasked with distracting the swarm, his suit is damaged. Caitlin and Cisco drive the S.T.A.R. Labs van to catch Ray and succeed in saving him. He and Caitlin talk a bit afterwards and seem to get along well, both being scientists and in the secret superhero game.

Caitlin and Ray see each other again in Autumn 2016, when the Dominators attack and the various teams come together to fight off the threat. They don't spend a lot of time together, but Ray talks with both Cisco and Barry and is comfortable with Team Flash, fitting in nicely with the three scientists who are of a similar disposition to his own.

In Autumn 2017 when the invasion of Earth-X Nazis require a superhero team-up, Ray and Caitlin both fight as their alter egos. After Martin is mortally wounded, Caitlin, who has a close relationship with Martin, tends to them both in the med bay and runs into Ray who asks about their condition. They're both very upset that nothing can be done to save Martin Stein and they share a hug to comfort each other.


A rare-pair, with Ray having dated Felicity and Caitlin usually paired with Barry of the science superhero boys. Add to this, they haven't a lot of one-on-one screen time to establish their relationship, although they share a lot of both common interests and friends, as well as both being superheroes and very kind people with big hearts.
