Powers and Abilities
- This version of the character is based loosely on the comic book character of Emma Frost, who was also the basis for the X-Men: First Class character of the same name.
- This version of the character was Kayla Silverfox's sister, Emma, though her last name was given as Frost in the trailer. The film never refers to her as anything other than Emma, including the credits. Being Kayla's sister also makes it more likely for her to be called Emma Silverfox than Emma Frost. Producer Lauren Shuler Donner confirmed that the character of Kayla Silverfox's sister from X-Men Origins: Wolverine who was previously thought to be Emma Frost is not the same character.
