Dick Grayson was the original Robin, but when he decided he wanted to grow up, he graduated to Nightwing.
Even now, Dick is still young and when he first became Nightwing he was a Teen Titan. That look was hilariously of its time and he currently prefers red to turquoise (why DC why?!) but this is the costume I think of as Nightwing’s (it even showed up in the cartoon, remember?).
Tim Drake is my favorite of the Robins, so I chose to focus on that costume.
Cassie Sandsmark is my favourite of the Wonders. While Wonder Woman is the icon and Donna Troy’s Wonder Girl preceded her by thirty years, Cassie is the Wonder Girl I personally connect with.
And this outfit has a lot to do with it. I love its silly nineties earnestness.
