Though many fans were disappointed that Nathan Fillion’s cameo as Wonder Man didn’t make it into Guardians of the Galaxy Vol. 2, Fillion sees the deleted scene as an opportunity for a future entry into the Marvel Cinematic Universe.
Fillion portrays Williams, who in Marvel Comics is Wonder Man, a superhero who moonlights as a Hollywood action star.
“If you know the Marvel Universe, Simon Williams becomes Wonder Man, becomes an Avenger.
James Gunn has stated that Nathan Fillion’s cameo can be considered canon, meaning that to him, Fillion is Wonder Man regardless of the fact that the scene didn’t make into Guardians of the Galaxy Vol. 2.
