While it’s been known for quite some time that the legendary Nathan Fillion will be make at least a small cameo on the upcoming Guardians of the Galaxy Vol. 2, recent photos from the set give some direct insight into just who he’ll be playing.
Several posters and a marquee reference Simon Williams, a character also known as Wonder Man within the Marvel canon. In the comics Wonder Man is a chemically altered superhuman rival to Tony Stark, due to his similar heritage as the child of a munitions industrialist. He’s been an Avenger and was involved in the Civil War plotline of the comics as well.
