X-MEN GOLD #1 begins with this new incarnation of X-Men (Kitty Pryde, Storm, Old Man Logan, Colossus, Nightcrawler, and Prestige AKA Rachel Grey FKA Rachel Summers FKA Marvel Girl FKA Phoenix) saving New York City from an attack by Terrax the Terrible. Most of the X-Men battle and defeat Terrax (spoilers...), but Kitty has a unique role in this fight.
You see, Terrax has control over the ground. In this battle, he uses his powers to knock over a skyscraper. Within seconds, this building will collapse to the ground and kills hundreds of people within. Not to mention the people on the streets and the people in the surrounding buildings!
Luckily, Kitty has the building to turn intangible. She also has the ability to make other things turn intangible by touching them. So she manages to phase out the collapsing skyscraper long enough for Nightcrawler and others to rescue the people within. Nice save, eh?
Nightcrawler and Colossus seem incredulous that she has this much power. Which makes sense, I guess. She is one person after all. This is pretty heavy-duty work, right?
Except that Kitty once single-handedly saved Planet Earth by phasing a giant bullet. That bullet was big enough to destroy the planet and dense enough to repel defensive weapons.
And since then, Kitty Pryde became a frickin' space god with the ability to turn into a giant space ghost. She even phased an entire planet during that story line!
So have a little faith in your new leader, X-Men! And bone up on your mutant history before your next mission!
