Who is your definitive artist for each character? I was surprised by some of my answers -
Cyclops - Paul Smith or Jim Lee
Archangel - Simonson
Iceman - Andy Kubert
Jean - Byrne
Beast - George Perez tbh
Wolverine - Byrne or Adam Kubert
Colossus - Smith
Nightcrawler - Smith
Storm: Paul Smith
Rogue - Jim Lee
Gambit - Jim Lee
Magneto - Jim Lee
White Queen - Cassaday
Kitty Pryde - Smith
Bishop - Romita Jr.
Havok - Neal Adams
Xavier - Andy Kubert
Psylocke - Jim Lee
Jubilee - Jim Lee
Dazzler - Silvestri
Longshot - Adams of course
Stepford Cuckoos - Bachalo
Magik - Bachalo
Cannonball - Capullo
I was surprised how few of these were Andy Kubert or Joe Mad who were the two artists at the peak of my reading. I am simply in awe of what an impression the From the Ashes trade made on me as Paul Smith might be my definitive X-Men artist despite his limited run and Byrne and Lee casting such large shadows.
If Pepe Larraz gets to be a solid backbone of the HOX era he might make it on the list. I simply adore his art and think he's just magic on the X-books.
