Mr. Freeze (Arkhamverse)

Batman: Arkham Asylum
Although not appearing in the game himself, Mr. Freeze's cell, which is in the same wing as Arkham's most deranged cases, can be seen in the Penitentiary area of Batman: Arkham Asylum, which can be scanned to unlock his bio, which reveals that he escaped prior to the game.

Batman: Arkham City
In Batman: Arkham City, Mr. Freeze is blackmailed by the Joker to find a cure for the TItan poison. He nearly completed it before he was captured by the Penguin. Freeze and his suit are displayed seperately in Penguin's War room and Museum respectively.

Once Freed he instructs Batman on how to defeat Penguin who's using his cryogenic weapons. Once back inside his suit he explains that the cure breaks down too fast to be of use and requires a restorative agent to work.

This prompts Batman to hunt down Ra's Al Ghul to retrieve a blood sample which contains the needed restoration agent. Once Batman gets back to Freeze, Freeze tries to force Batman to retreive Nora from Joker, prompting a long Boss fight in which Batman is able to neutralize his suit's defences and defeat him, smashing open his dome in the process.

Unfortunately Batman Discovers that while he and Freeze were fighting Harley Quinn broke into the Safe and stole the cure. Freeze gives Batman a supply of Cryogenic bombs hoping that he'll be able to rescue his wife.

Psychological Profile (by Dr. Young)
Mr. Freeze

Real Name: Dr. Victor Fries

ESCAPED!!

Psychological Profile: Another surprisingly intelligent inmate. Fries's narcissism and antisocial disorders are surpassed only by his intense fixation on his late wife Nora. His obsession with Nora's memory has developed into a variety of psychopathic behaviors, worsened by his narcissistic egomania and lack of concern for others. Fries's peculiar medical condition - which keeps his body temperature below zero and necessitates a variety of complicated and security precautions - only furthers his antisocial tendencies.

Additional Notes: Yet another inmate here at the asylum who was formerly a doctor; certainly an odd pattern.

Treatment is difficult due to the frigid temperatures I am forced to endure in his presence.
