Though the Season 4 finale of Arrow saw the unofficial disbanding of Team Arrow, Oliver Queen won’t be alone when the show returns this October. At this past weekend’s Heroes and Villains FanFest at the Meadowlands Exposition Center in New Jersey, recurring guest-turned-regular Echo Kellum said there’s a very terrific future ahead for the brainy and athletic Curtis Holt.

When asked if Curtis Holt will become the DC superhero Mister Terrific like his comics counterpart (whose name is Michael Holt), Kellum told Inverse that “it’s definitely going to happen this season. Ninety-percent gonna happen.”

Putting aside that ten percent caveat, Kellum explained that Curtis’s life will change as he takes on more important duties. “Battling with that aspect of being a part of the team and getting into the field more, protecting people, I think it’s going to be a really fun season for him to see what type of hero he’s going to become,” he said.

Although Kellum debuted as Curtis Holt in Arrow only last season, the character Michael Holt has saved the world in DC’s comics since 1997, starting with the series Spectre. A genius inventor and Olympic gold medalist, Michael Holt was devastated after the death of his wife and child, but then inspired by Terry Sloane, the original Mister Terrific and member of the Justice Society of America, to push forward. Holt takes up Sloane’s mantle as Mister Terrific and arms himself with high-tech devices, such as his signature T-Spheres, which specialize in nanotechnology.

Curtis has not yet donned the Mister Terrific identity in Arrow, although some of his gear have shown up as working prototypes, at which Emily Bett Rickards’s Felicity has gawked. Curtis also does not have a wife and child in the series but a boyfriend, which Kellum hinted will factor in when Curtis becomes a superhero.

“I think it’s going to be really interesting to see how that’s going to play against his backdrop at home too,” Kellum teased.

Arrow returns on October 5.
