You don't like Alora ?!! Ha, I admit she is kind of a "sweet muffin" character, but after spending some time with her in my party, I actually grew to like having her pleasant voice and good thief skills around.
But anyway for companions in BG III, I would love to have just a simple neutral fighter that any type of party could use. Nothing too special in the background, maybe just a spritz of gnomish in an otherwise human family tree ... a "gnuman", if you will. And his first name could be Gary, which makes the full name Gary Gnuman ...

My name is ruin, my name is broken
My name is shameless, I'll tear your world open"
