In your own opinion, who do you think is the definitive Batman Besides Bruce? For me, it would be Terry Mcginnis. Mostly because he was never a Robin, and became Batman in almost the same way Bruce did.
Dick then Terry.
Personally I always liked Dick better as Nightwing doing his own thing
I love Nightwing but if Bruce wasn’t Batman then I couldn’t pick anyone else besides Dick to pick up the cowl.
