For those unfamiliar with Jack Harrison aka Jack Flag, he is a character that has bounced around Marvel comics looking for a home.
Jack Flag is an easy-to-spot character in the comics thanks to his signature red, white and blue hair, but that is not the case for this character, who has short black hair instead.
With S.H.I.E.L.D. spending at least part of the season in space, introducing Jack Flag – who has made more of an impact in the cosmos – would be an interesting get.
Season 2 brought fans both Quake and Mockingbird, season 3 introduced now season-regular Yo-Yo, and season 4 brought Ghost Rider and The Patriot (Jason O’Mara).
