Cyclops: Ok, no more orcs. Where's Frodo with that f***in ring? The big eye's a pain in the ass.
X: No Idea. The Eye appears to resist mind control... He is powerful.
(some other X-man): So... waiting is fun...
Cyclops: ...Screw this! (takes off glasses)
BOOM! No more tower, no more Sauron. Frodo gets launched into Mt. Doom from a catapult for being late.
And I disagree with the "any X Man beats mordor". Jubilee would get her ass kicked by orcs. Oh, and Xavier is like a crippled, uber powered wizard. But debatably not quite as badass. He could take Saruman.
