Sweet Christmas, Everybody!!!
There are two reasons to hunt this issue down and own it.
The first is this :
Dave Cockrum drawn Excalibur! Look how cute Lockheed is! He does not want to be dressed as Rudolph.
The other is two page, three with an extra credits page and additional covers, Ghosts of Christmas Comics Past by Barry Dutter.
“X-MEN # 143 contained a Christmas classic by the ultimate X-MEN team – Chris Claremont, John Byrne and Terry Austin! The story was called “Demon,” and any similarity to the movie ALIEN was purely intentional. The issue found then-X-Man Kitty Pryde alone in the X-Mansion on Christmas Eve, forced to fight a savage N’Garai demon all by her lonesome! This was Kitty’s first real test in solo action, and she passed with flying colors. (Since Kitty will eventually grow up to look like Sigourney Weaver, this came as no big suprised!)”
The issue also has stories starring Wolverine, New Warriors, Spider-Man, Punisher, Doc Samson, Thanos, Iron Man and Daredevil.
