Curtis hasn’t officially been deemed Mr. Terrific yet, but all signs point to his introduction this season.
Mr. Terrific has always been a character who embodies a true Renaissance man: skilled martial artist, exceptional athletic abilities, and highly intelligent.
Could Mr. Terrific be the avenue with which Arrow brings the Spectre to life?
Of course, Kellum doesn’t give us too much insight into his character’s arc in season 5, so we’re left to speculate about his development as Mr. Terrific.
