The best X-men villain.

Silver Surfer is the best and coolest Villain. I can't wait for the Fantastic Four movie......

There are a some really good x-men villians. I really like Mr. sinister. He never made it to the movies, but is really great in the comics. He's an evil geneticist who worked for Apocolypse (another GREAT villian), although one of his biggest projects was to mess with the genes of Scott Summers and Jean Grey so they would have a kid who could destry Apocolypse, since he thoguht that Scott and Jean's kid would be the most powerful mutant ever. He also assembles the Mauraders, who were responsible for the Morlock massacre, and has a behind the scenes hand in the Hell fire club. The Wiki on Mr. Sinister explains things much better than I am, so if you are really intersted, I would check that out. I also like Sabertooth, when it comes to Him and wolverine really going at it. The ongoing rivalry between them is really great. it wasn't played up in the movies that much, but in the comics it's epic.

for me it's APOCALYPSE, apocalypse is a mutant who possesses super human strength which he can augment by psionically drawing on outside energy sources. he can alter the atomic structure of his body at will in order to change his form. he can even increase his size by taking on additional mass from a presumably extra-dimensional source. through his ability to alter his form, apocalypse can give himself virtually any superhuman physical power. apocalypse has an extraordinary long life span that has already lasted thousands of years. he can survive for weeks without food or water and can rapidly recover from injuries that would prove fatal to normal human beings.

I would choose Magneto as the best X-men villain.I hope there would be another episode of X-men where in the power of Magneto and his villains will be greater than the previous episode.

Magneto would be number 1 for me. Can you imagine having the power of magnetism? You could control anything. Many people don't know this, but everything has an electron, so Magneto pretty much could control anything, not just metal.

I liked the Dark Phonix, she didn't stay around very long ( a little longer in the comic ) but I liked Jean Grey just doing whatever she wanted being bad instead of good. Taking center stage instead of been behind cyclops.
