Frost is okay i guess. far from the best to use but not the worst either. She's not bad to use but wouldnt be my first choice. she has at least 2 big kicks that she uses that lead her wide open if they fail to land especially since it takes her so long to get back into a stance she can block from. Frost made her debut in MK deadly alliance. She was supposed to be a student of a Sub-zero but ended up betraying in her quest for power which ultimately became her own downfall. Due to her inexperience as a necromancer she couldnt handle the medallion the first time and her ice ended up encapsulating her till Taven (again) freed her in armageddon. She immediately tries the whole thing again. We dont see her again till the MKX comics where she is seen fighting cassie cage in an underground cage match and loses. She eventually pops back up in MKX as sub-zeros student and immediately attempts to attack Hanzo after he and sub-zero are about to settle their differences. she is frozen by sub-zero and basically banned from the clan. she comes back in MK11 this time selling herself out to sektor and kronika as a lin kuei die hard member.That felt like it was a her problem in that story. She feels like she was trying to be what sektor was and the writers didnt know what to do with her. Initially when i saw her for the first time i thought frost was sub-zero's sister or something because we never even had mention of a female ice ninja before. turns out she's just a crazy fan. I liked her design though. This version of frost is my favorite version of her and its kinda nice that it returned from MK 1 as a kameo
