Iron Man #197  1985 Marvel Comics: John Byrne Cover

"James Rhodes (in Tony's Iron Man armor) turns Stewart Caldwell (Aka Thundersword) over to the LA police following their battle downtown[1]. As Cadwell is being locked up, Iron Man turns over his Shazam Award, the object that seemingly granted him his powers as Thundersword. However, alone in his cell, Stewart rationalizes that since his powers were derived from his imagination, that the limitations were also the product of his imagination as well. Through sheer will power, Stewart causes his Thundersword powers to return and uses them to escape from his cell, flying away on his winged steed Bromir. When Iron Man attempts to stop him, he is easily over powered in battle. Finding that Rhodney is beneath his notice, Thundersword rides off to freedom."
