(Secret Wars II#1) - Stewart Cadwall was on the phone with his agent, arguing the merits of including more violence in his television scripts, when the essence of the Beyonder arrived, intrigued by Cadwall's angry voice. The Beyonder sought to learn more about humanity, and when Stewart marveled at his powers and wish he had them, the Beyonder distributed some of his to the man, through a Shazam Award Cadwall was wielding as a weapon. Transforming into Thundersword, a character he once created, Cadwall decided to lash out at the mediocrity of the world. He then created a winged steed he dubbed Boromir, and flew off.

Thundersword attacked the NBC studio, upset that they had forced him to rewrite some of his scripts. Several members of the X-Men and New Mutants arrived, believing him to be the Beyonder. Before they could attack, Thundersword did the same, and then turned his attention to the McDonalds they crashed through. Captain America and Iron Man arrived shortly thereafter, and engaged Thundersword in combat. When Captain America threw his shield, knocking the sword out of Thundersword's hand, he reverted to his normal form (and the sword reverted to the Shazam Award). Powerless, Cadwall was overcome with the realization that he'd destroyed the place he worked at.

(Iron Man I#197) - When Iron Man delivered Cadwall to the local police, Cadwall realized that the power the Beyonder had bestowed upon him wasn't in the award, but rather, in him. He reverted back to Thundersword and formed a new sword, busting out of the jail. He also reformed Boromir, and flew off on the winged steed. When Iron Man tried to stop him, Thundersword quickly defeated him and left. Realizing his armor was no match for Thundersword, Iron Man contacted Tony Stark, and the two of them came up with a plan to imbue the armor with more power through a generator. With the extra strength, Iron Man easily resisted Thundersword's blows, and knocked him into the ocean with one punch. When he went to retrieve Thundersword, he was nowhere to be found.

Comments: Created by Jim Shooter, Al Milgrom, and Steve Leialoha

A really cool looking villain. Too bad he only lasted two months before disappearing. Perhaps he's still out there somewhere, retaining the power the Beyonder gave him.

In Secret Wars II#1, the Shazam Award, which Cadwall apparently won for one of the shows he wrote, had a clear base with trapezoid sides. In Iron Man I#197, it had a solid brown base that was vertically high and rectangular in shape. Maybe Iron Man picked up the wrong object after the fight?

Obviously, the Shazam Award, with it's lightning bolt, is in homage to the Fawcett/DC character Captain Marvel.

Marian fell asleep while the Beyonder was in their home, and giving Stewart superpowers. Some girlfriend. Perhaps she fainted?

Thundersword/Stewart Cadwall is based on comics writer Steve Gerber, whowas working in television at the time.  Don't believe me?  Compare Stewart Cadwall to a photo of Gerber in the 1980's. --Shad Z. Daly
