Daniel Cudmore, who played Colossus in three X-Men films, will return in the latest installment of the franchise, X-Men: Dark Phoenix.
Since the X-Men are expected to encounter the Shi’ar in X-Men: Dark Phoenix, Gladiator could make an appearance.
Canadian actor Daniel Cudmore will be joining the cast of X-Men: Dark Phoenix.
It’s also worth noting that if Cudmore were to appear in Dark Phoenix, his appearance could be disguised with CGI to keep him from looking too similar to his Colossus character.
