Is it Cyclops or Wolverine? I am more inclined to think that it's Cyclops as he never has established any lasting relationship beyond Jean and possibly Emma as cable has never been as close to him as he would have liked just like his own father. the same goes for Rachael whereas Wolverine has formed much more lasting relationships with alpha flight jubilee Jean mariko Laura Deadpool etc. for him to remain the loner he was. funny isn't it how close he follows the Batman loner archetype who is surrounded by family and close associates. anyway who do you think is the loner of the x men? a argument could be made that they are all loners isolated from humanity but who do you specifically think is a loner/misanthrope?
