The first version of the cryo-suit was an "air conditioned" costume, designed by Mister Zero in order to help him remain in temperatures below zero. The suit was equipped with a special glass helmet connected to a gas tank located on the back of the suit. Besides keeping the man inside the suit in cold temperature, the suit had no other special capabilities.
The second Cryo-Suit was much bulkier and provided further protection than the first version. The body was protected by a thick green over-all. The hands and feet were protected by white gloves and boots and the glass helmet was replaced by a steel helmet with a glass visor. This suit resembled an space suit, but the gas tank was not removed. The tank provided the cold temperature for the suit and also the chemicals needed for the cryothermal gun.
The third Cryo-suit was similar to the first one, as it eliminated unnecessary bulkiness, allowing Freeze to move freely. The suit was almost skin-tight and it featured icicle designs on the boots, gloves and torso. The previous tank was also replaced by a belt, which connected the ice gun with a regulating cable that allowed the gun to work properly. The steel helmet was also replaced with a glass helmet to increase the sight and it incorporated a transmitter to command Freeze's minions or henchmen. The final upgrade was the inclusion of visors to protect Freeze's eyes from the cold temperature.
The cryo-suit was an armored battle suit created and developed by Mister Freeze in order to keep his body at temperatures below 0 °C (32 °F). In order to do so, the suit concealed a high concentration of chloroflourocarbon (CFC) gases under pressure.
Freeze's cryo-suit protected him from a bomb attack by The Ventriloquist's henchmen but the helmet of the suit was damaged by a sniper that managed to get a direct shot to the helmet's glass, causing the gases to leak outside due to the pressure, raising the suit's temperature to normal levels, which were lethal for Freeze.
After the gang war that broke out in Gotham, Mister Freeze was recuited by Black Mask and he provided Freeze with a new and improved Cryo-suit, which was less heavy than the previous one and was capable of withstand gunshots and attacks with explosives.
Besides keeping Freeze's temperature below zero, this Cryo-Suit enhanced Freeze's strenght three times above his normal strength. When Freeze's body decayed, he built a new suit that was entirely robotic, except for the head, which was Freeze's only remaining part of his body. This suit was stronger and allowed Freeze to destroy strong structures.
- There have been at least 10+ different variations of Mister Freeze's Cryo-Suit over the years within his New Earth incarnations. Many other examples of his various suits appear throughout his appearances elsewhere.
