- It was unclear if Emma has any possible relation to Emma Frost, who appears in X-Men: First Class. They appear to be two different characters. In a promotional video of X-Men Origins: Wolverine, the character claims that her name is "Emma Frost". However, given that Emma's surname wasn't mentioned in the film, the fact that she's Kayla's younger sister, that her sister's surname is Silverfox, and that Origins takes place in the late 1970s, it can be safely assumed (especially in light of First Class, which takes place in the early 1960s) that the Emma in Origins is definitely not the same Emma in First Class. Additionally, the Emma of First Class has more in common with her comic book counterpart than the Emma of Origins. Another indicator that they are two different characters is that in X-Men: Days of Future Past, Magneto reveals Emma Frost to be dead. It was noted that Emma Silverfox does not exhibit the Emma Frost's traditional telepathic abilities.
