Continuity mistake: Robin calls up Cyborg as he makes his way to Steel City. When we see Cyborg on screen, the sky is daylight-blue and a bit cloudy. When Cyborg is seen personally, however, it is night outside - i.e. a dark clear sky full with stars; and when he activates the T-Car's hover function, it is still night, but the starry sky has suddenly become heavily clouded.
Continuity mistake: Steamroller has two hands encased in cone-shaped gauntlets, but whenever he puts them together to pin someone down, the gauntlets assume a cylindrical shape. It happens every time we see this character in action throughout the show.
Chosen answer: This is Dick Grayson who will later become Nightwing.
