Nathan Fillion as Starfox
Starfox may be an obscure character for those unfamiliar with comics, but he shouldn't be overlooked. Aside from once being a member of the Avengers, Starfox is also Thanos’ (that purple guy at the end of the movie) brother. Charming, charismatic, and able to instill a sense of euphoria in people within his proximity, it’s these qualities and more that make Nathan Fillion the ideal actor to portray Starfox on the show. A logical choice since Fillion does those things in real life anyway.
