[Marvel 616] What power tier is Kitty Pryde?

Her powers make her seem too powerful to be a street tier, and she has some crazy feats that could possibly make her a city buster. She could also take on characters well above street tier.

How strong is she exactly?

Bear in mind that power tiers are nebulous things that only really rely on how the hero operates. Wildcat, for example, is street tier on his best day, but he's been JSA since day one.

On the opposite side of the spectrum, Spider-Man is someone who the League wouldn't have minded recruiting, but he's considered a street level hero because that's the kind of crime he usually handles.

Batman and Moon Knight are very much the same in terms of how they operate, but Moon Knight is street level while Batman is world-class.

Power tiers are largely how the character treats themselves and what they do, not what they're capable of. Kitty Pryde could screw up a lot of things or kill a ton of people, but she doesn't. Much like Spider-Man, she operates on a lower level than she's capable of.
