The Flash: Ranking Every Character From Worst To Best
6. Caitlin Snow
Perhaps the most under-appreciated member of Team Flash, Caitlin Snow has been responsible for some of the show's most compelling storylines and yet it still feels like the writers have only begun exploring her potential.
Originally a colder and more stern character (due to the loss of Ronnie), the inception of Team Flash allowed her to grow as a person and ultimately overcome the grief as she found happiness in her new friendships. But that was only the beginning of her journey, as this struggle with both sides of her personality would later manifest through the arrival of her icy alter-ego Killer Frost.
From siding with Savitar to battling Cicada, Caitlin has experienced a lot in terms of switching sides and, after all this time, she has finally reconciled both parts of herself so that she and Killer Frost could co-exist in the one body and, dare we say it, even become friends.
Danielle Panabaker's gentle performance continues to make Caitlin a Team Flash gem, and she's clearly had a lot of fun bringing the badass Killer Frost to life. Let's just hope that she's given more to do in the sixth season.
