## Character Information

### **Portrayed by**

Danielle Panabaker
Victoria Askounis (young)

**Dr. Caitlin Snow** is (formerly also known as **Killer Frost** and simply **Frost)** a major character in the Arrowverse. She is the tritagonist of the television series *The Flash* (however, she was the secondary antagonist of Season 3 of the series) and has made guest appearances on *Arrow*, *DC's Legends of Tomorrow*, and *Supergirl*.

Caitlin is a scientist at S.T.A.R. Labs and the best friend of Cisco Ramon and Barry Allen. She served as both Barry's close friend and closest confidante who could alternate between her Snow identity and her "evil" persona **Killer Frost**. However, when they were able to coincide with each other, Killer Frost became an anti-hero. The two eventually split and developed a sisterly bond with each other.Caitlin is the daughter of the late Dr. Thomas Snow and Dr. Carla Tannhauser, the widow of the late Ronnie Raymond. She is also the former lover of "Jay Garrick", before discovering his true identity as Hunter Zolomon, and the ex-girlfriend of Julian Albert.

## Overview

She debuted in the *Arrow* episode, "The Man in the Hood." She later made her first major appearance as one of the main characters of the spin-off series, *The Flash* and a guest character on Supergirl and Legends of Tomorrow. She has done so by becoming  a major character in the shared crossovers, *Invasion!, Crisis on Earth-X, Elseworlds*, *Crisis on Infinite Earths* and *Armageddon*.

## Trivia

* The first allusion to Caitlin being Killer Frost and Ronnie being Firestorm is when she tells Barry Ronnie used to say that they used to be "fire and ice."
	+ The fact that Caitlin sometimes acts cold or distant when she suffers a loss (Ronnie and Jay) and later, the time Barry disappeared in the Speed Force.
	+ Her doppleganger from Earth-2 is a metahuman, Killer Frost.
	+ She claims to Cisco that she will never truly become like Killer Frost, alluding to them being a split personality.
* Her father has a split personality like she does: while Caitlin manifests as Killer Frost, Thomas manifests as Icicle.
