Alluka Zoldyck & Nanika
physical attributes Alluka will have black cocker spaniel ears most of the time. A black cocker spaniel will be her default form, but she (and especially Nanika) may take the form of whatever animal she thinks will make someone happiest.
reasoning What Alluka and Nanika both want most in the world is to be loved. When Killua tentatively asked whether she could be happy if he were the only person to love her (since the rest of their family doesn't view Alluka as a person or part of said family), she said she would be the happiest person in the world. Alluka's no doormat. She stands up for Nanika, her best friend and often sole companion, from anyone, even Killua, who will mistreat her. You can't love one and not the other. Nanika's whole being, whole reason for granting wishes, is to be loved, to be told she's good. There's no moral judgment on anyone's wishes.
As a Familiar, she'll focus on trying to support others and make them happy as before. What she needs is for at least one person to be as invested in her well being and development as she is in theirs. Her instinct is to be codependent. As a kid, that's okay, but she needs support growing into an independent person confident she is loved without strings attached.
