2. X-Man

One of
the coolest characters in all of comics - let alone the X-Men comics - is Nathaniel "Nate" Grey. Originally created artificially by Mister Sinister, using the DNA of his universe's Scott Summers and Jean Grey, Nate is essentially an alternate reality version of Cable. Using his cross-dimensional powers he has, however, ended up in the main (616) Marvel universe and has represented both the sides of good and evil. Created to be the ultimate mutant, in addition to his cross-dimensional powers Nate possesses telepathy, telekinesis, psychometry, precognition and the ability to exist as living energy - meaning that he essentially can't die. It really would be great to see a live action version of the character. And speaking of
ultimate mutants...
