Karlach from Baldurs Gate 3
She just seems like a crapton of fun. Though I fear that a night out with her might end up in a bar brawl. But thats just part of her charme.
Frenchi from The Boys
Same reason as Karlach, just replace bar hrawl with drug overdose.
Emily from Stardew Valley
Same reason as the other two, minus the brawl or the overdose. Though I'm pretty sure that a night out with Emily will result in a hangover from hell.
Fane from Divinity 2
Fane is supposed to be this supersmart character. And you know what they say: "Its hard to write a character that is smarter then you". In Fanes case they succeeded. I would really love to listen to him about physics and philosophie. I think he would have some interesting perspectives, especially about what is going on in the world right now.
The Djijn from Aladdin
For obvious reasons
