Inspiration for the name comes from the character Katelyn/Killer Frost from the show The Flash.
A wonderful adopt I got from the amazing artist

She’s the mate to my character Sub-Zero. She loves her friends, family and her mate. She loves to give hugs and cuddles to her mate and friends. She does have a freezing ability but prefers not to use it. She’s a very fierce fighter when crossed and will do what she has to to defend her mate and her loved ones.
