Assault on Arkham Incident
Killer Frost was initially seen robbing a Gotham City bank, freezing the occupants inside, and engaged the G.C.P.D. in battle after her escape car left her behind before she was apprehended and forced to join the Suicide Squad. Frost eventually woke up in a secured room alongside the other Suicide Squad members with her hands bound together in a metallic mechanism. King Shark briefly attempted to eat her, but was quickly neutralized by her. After being briefed alongside the rest of the Suicide Squad by Amanda Waller, Frost was gassed and woke up locked to a metal chair that was soon after enclosed in a metal crate that was dropped into Gotham City via aircraft. During the fall, Frost's parachute malfunctioned, she crashed into King Shark, and the two of them landed on top of a parked vehicle that was crushed on impact. Soon after, Frost, along with the rest of the Suicide Squad entered the sewers via a manhole, and she sat atop King Shark's shoulder for the duration of the trek to the Iceberg Lounge. After gearing up there, Frost was contacted on a secure line by Waller and was given the secret task of assassinating the Riddler, unbeknownst to the rest of the team. Frost was snuck into Arkham Asylum through the Arkham Morgue in a body bag naked by a disguised Captain Boomerang. However, the latter proceeded to knock on her head three times hard enough to give her discomfort in order to sell the act, which resulted in her, after awakening and killing the orderly, proceeding to exact revenge by kneeing him in the groin. During the infiltration of Arkham Asylum, Killer Frost located the Riddler via a computer in the Security Room. Killer Frost decided against killing him when she learned the reason that she was sent to assassinate him - Riddler knew how to disable the nano bombs that were implanted in the members of the Suicide Squad. After the Joker broke free and set all the patients of Arkham loose, Frost tried to escape by stealing a police car, killed an inmate in the process, and froze Two-Face's head. However, Bane, one of the released inmates, grabbed and threw the car that Killer Frost was trying to drive, which caused it to explode, as it is unsure whether she survived the explosion due to never being even mentioned in later content and the Arkham Game series has ended and most likely the comics won't release a clue, her ultimate fate is unknown.

- In the original comics, Louise Lincoln was a scientist who willingly transformed herself into a superhuman after the death of her close friend, Crystal Snow, the original Killer Frost. Louise assumed the identity of Killer Frost out of mourning and wrath for her friend's death at the hands of superheroes and became a murderous vigilante as a result. Whether or not this applies to the Arkhamverse version of the character is unknown.
- In Batman: Arkham Knight, there were stores named Frost Diamonds and Snow's Drug Store. That was likely a reference to Caitlin Snow, who was another incarnation of Killer Frost.
