Wolverine... easily... by miles
but I was always a big fan of Gambit. Not used in the movies at all despite probably being the second coolest mutant next to Wolverine. Plus he had the New Orleans lingo...
i thought Icemans powers were dope too but they made had to make him gay... still dope though
Colossus was cool. I used to get called Beast from xmen in HS because I was strong, fast, with a beard, a lot of hair, and glasses
.. so i was always fond of him
Rogue and Storm were the sexiest. Jean and Cyclops was annoying trash
