i'm a casual fan, but I still think(personally) that sometimes, these characteristics become so common. I would recommend making dink feral, make Damian the softie, Duke the menace, Cass is act so knowing it's scary, Tim isn't a coffee addict from what i've seen(I think he's more into energy drinks and sudden naps but I could be wrong). pretty sure he isn't also a weak little baby, he's capable, had to be considering that he was alone somewhat since his childhood and so on and so forth. But still, not to hate those other characterizations! I still eat them up, every time <3
What a fucking fandom, huh!
