Real Name: Emma Grace Frost
Code Name: White Queen
Age: Don't know, late 20's I guess
First Appearance: Uncanny X-Men #129
The former teacher of the Hellions (they're all dead by the way), she is the new co-teacher of Generation X. Her goal is to teach them so that they won't get killed off like all of her Hellions did. She's been suffering from this guilt trip because of this. Emma is one of the most powerful telepaths in the world, and she often uses that power to manipulate things (the bad guys) or cloud peoples minds, or fry them. Whatever. She has this thing for Sean, there's this weird love thing going on there. You'll just have to read the romances section to find out more.
