1. Grant Gustin

Appeared in: The Flash (2014), ArrowSupergirl, DC’s Legends of TomorrowBatwomanVixen

Grant Gustin’s performance as Barry Allen on The Flash has taken on such a life of its own over the past decade that it’s hard to remember a time when he wasn’t playing the Scarlet Speedster. That‘s how good a performer he is.

Initially overcoming some ludicrous controversy in regards to his unexpected casting, he brought out all of the qualities one would associate with Barry Allen throughout his two-episode stint on Arrow back in 2013 and magnified all of it when he began leading The Flash the following year.

Gustin’s performance has evolved over the decade that he has played the role but he’s never lost that infectious charm and effortlessly heroic aura that make up so much of what his Scarlet Speedster stands for. And, for the record, throughout those ten years, he has delivered some incredibly powerful performances, showcasing why he’s one of the strongest actors on TV today.

Without a doubt, the definitive Barry Allen in every single way, Gustin hasn’t just embodied The Flash… he is The Flash. And he’s done such an outstanding job that we’re not sure anyone will ever be capable of outshining the magic he created.

Keep running, Grant! Thank you for reinventing Barry Allen for a whole new generation.
