I kind of hate this too.
It seems convoluted in a way that the writers went, “Oh shit, Terry’s backstory is just like EVERY other Robin . We gotta shake this up somehow.” In a retroactive sense.
One of the things I genuinely LOVE about Beyond is how utterly TERRIBLE Terry is at being Batman. He’s dogshit. He gets his ass beat nearly every episode, and he hardly has any of those moments of, “I’m so lethal I’m scary.” Like Bruce does in the TAS. It makes sense, seeing as he’s basically running partnerless on his first year out as Batman without any ninja training, but I really like the arc it gives him. He’s just this street punk who actually acts like a punk when he’s in the suit. I feel like the previous Robin’s were pitched like this, especially Jason, but Terry really sells it with how often he fucks up.
I love it.
