Full name Belladonna Bianchi, he goes by "Donni". He's the oldest of 9 and the heir to the Bianchi mice mafia. He takes his duties to the family very serious, though he's often hot headed and brash; something that his father [the current don] admonishes him for frequently. 

He's closest to one of his little sisters, Isabella. She's a spunky squirt who wants to be a cowboy. Donni befriended a manta ray, Rei, when he was a preteen. They're very close and Donni enjoys hanging out with Rei when he's not busy busting chops. 

Rei and Donni has a mutual crush on each other, but Donni is too stubborn to admit it. That and the fact that two boys can't like each other like that! They're just bros! Really good bros! Bros that sometimes hug and hold hands and maybe kiss on the lips but yknow - no homo dude!
