Not a series but Magic the Gathering
I’m going to go with who I use as Commanders for this one.
Character I’d want as a best friend.
Surrak Dragonclaw. We can do cool things like punch bears together, even if they are twice the size of normal bears.
Character I’d want as a parent.
Aurelia, the Warleader. Then I get to untap all my life choices and take an additional childhood right? Right?
Character I’d want as a sibling.
Nahiri, the Lithomancer. She’d share her toys right? And planes-walking is genetic isn't it?
Character I’d want as a significant other.
In responce I choose Derevi, Empyrial Tactician. Now that the changed the rules for tuck our love will never end. So long as I have 4 open mana.
Character I’d want as a child.
Alesha, Who Smiles at Death. She is my tiny leader making her an appropriate choice to be my tiny baby.
Character I’d want as a weird inlaw.
Tasigur, the Golden Fang. A powerful relative to be sure. Shame about that dragon. But he does make a good necklace.
