My most random Duke headcannon is that he would have a pet rabbit.
The rabbits name is Bat-Bun and they go paroling together sometimes.
Duke teaches Bat-Bun all the cute trick like playing soccer and giving high fives.
Damian often goes over to Duke's to play with Bat-Bun, even if Duke isn't there. He often comes home from patrol to Damian and his mum sitting together and talking while feeding Bat-Bun sweet potato.
Duke threaten to steal Damain's mum in retaliation.
Damian threatens to steal his rabbit if he tries.
They both settle for playing soccer with Bat-Bun together.
