Unsurprisingly, Brenton Thwaites’ pitch for Dick to rock long hair and a mustache in Season 3 didn’t fly with the Titans team, although Nightwing has gone for a mullet on the pages of DC Comics and even in Batman: The Animated Series, so longer hair on Dick Grayson isn’t unprecedented!
Still, I’m on board with short hair (and no mullet!) for Dick in Season 3.
Ditching the Robin identity to become Nightwing doesn’t have to change his entire look!
