The Most Ludicrously Underwhelming Uses of Marvel Girl's Powers--Chapter 7

Until the very next page:

So, while bound, and without using any mutant powers, Charles Xavier also manages to trip the dreaded Ogre.

Which means: Jean Grey is precisely as powerful as a hog-tied, powerless paraplegic.

(It also means the Ogre really is a bit of a puss, too...)

Oh, Jean...
