10 Worst Things Robin Has Ever Done
2. Dick Grayson Cheats On His Fiancé
With the relationship between Barbara Gordon and Dick Grayson being one that developed slowly from when the pair began working together when they were young, it's only natural that they've had some up and downs here and there - and that some of these would involve them making the kind of sketchy decisions that people still learning about the world and themselves are prone to.
However, the absolute worst of these happens when the pair are adults, as Dick's reunion with Barbara after she was paralysed by the Joker is maybe the first Robin's most morally questionable moment to date.
After the pair reunite, they share a night together, and then the following morning Dick hands her a letter - inviting her to his wedding with Starfire.
It's not only a complete punch in the face to Barbara, who is understandably heartbroken, but also to Starfire, as he literally cheats on her while thinking about their engagement.
