The T-Spheres are autonomous mini-drones invented and used by Curtis Holt as Mr. Terrific. The spheres have several offensive and defensive capabilities, such as a self-targeting projectile.
After Felicity was fired, Curtis quit his job at Palmer Tech and joined Team Arrow, where he continued working on the spheres in order to help him fight crime as Mr. Terrific. Although at first they were not functional, by the time the team encountered Vigilante, Curtis used them successfully to knock him out.

- Curtis Holt named two of his T-Spheres Kodo and Podo after "Dar's thieving ferrets on The Beastmaster".
