A Brief Overview
Roy Thomas was the FIRST Editor-in-Chief at Marvel--After Stan Lee stepped down from the position. Roy is a longtime comic book writer and editor. Thomas has written comics for Archie, Charlton, DC, Heroic Publishing, Marvel, and Topps over the years. Thomas currently edits the fanzine Alter Ego for Twomorrows Publishing. He was Editor for Marvel comics from 1972-1974. He wrote for several titles at Marvel, such as Avengers, Thor, Invaders, Fantastic Four, X-Men, and notably Conan the Barbarian.
It was also Roy Thomas who recognized the writings of one Dennis "Denny" O' Neil (who would one day become Editor for DC/creator of Arkham Asylum/ Ra's al Ghul/John Stewart) from a newspaper article Thomas had read. Roy reached out to O' Neil and got him to pencil a script-test for The Fantastic Four. Shortly after Thomas showed the script to Stan Lee, who promptly hired O'Neil.
Character Creations--Oh My!
Roy Thomas is still an advocate for creator rights. So when working for Marvel he was well aware of his contract and therefore when he had to come up with new characters many times he would take characters that were already present in the Marvel Universe and "revamp" them ( "Revamp" get it? Because he created Morbius). Two great examples are The Black Knight and Ghost Rider!
Roy helped create dozens of hugely popular characters including the following:
All Star Squadron
Black Knight (Dane Whitman)
Kevin Sydney (Changeling)
Valda The Iron Maiden
Wendell Vaughn (Quasar)
Wildcat (Yolanda Montez)
This list is just a small sampling of the popular characters Roy added to both the DC and Marvel universes
The Wolverine Controversy
He is also a co-creator to Wolverine (though he does not get ANY credit--He should be sharing Credit with the other 3 credited creators--Roy Thomas was the Editor for Marvel at the time of the characters creation. Roy chose the name "Wolverine" over "The Badger" at a luncheon/meeting with both John Romita and Len Wein. Roy speaks openly about not getting credit and was overly surprised to first hear he was not getting any credit on the popular character who appeared under his reign as Editor in Chief at Marvel.
The 2nd Editor at Marvel Comics Steps Up
Roy became the first editor to take the reigns of Marvel Comics after Stan Lee. His list of creations for Marvel is a very long one.
Working for DC
While working for DC, Roy made a plea to the editor to change the company's name to combat more with Marvel Comics, his suggestion was "Dynamic Comics." The editor rejected the idea. At DC comics Thomas worked on All Star Squadron, Arak, and Captain Carrot and his Amazing Zoo Crew.
Thomas' Alter Ego won the Eisner for Best Comics-Related Publication in 2007.
In 2011 Thomas was inducted into the Eisner Awards' Hall of Fame.
