Don't know if he counts, but I love Balthazar. He's a show stealer. Great VA, has fun dialogue, an intriguing backstory, and he looks striking.

I also think that while Cazador's (he probably doesn't count, either) dialogue is goofy and so is his delivery (very on the nose) I've grown very intrigued by him because of his Detect Thoughts dialogue, I think it's great stuff.

Auntie Ethel's great. That's it.

Naaber is a gag NPC, sure, but I also really like that his spirit is so indomitable and set on talking it completely skips Speak with Dead rules if he's died. It's kind of undertaley.

I like any story with intelligent or misunderstood undead so I kind of like all of Mystic Carrion's rebel "lackeys".

Not striking, but the lady at Sorcerous Sundries who asks you to be quiet has a very pleasing voice. Might be my ASMR brain talking.

Araj is kind of fun honestly. She's insane. The epilogue has her IndianaJonesing her way to Oblodra's ruins or something. That crazy squidscrewer is getting herself killed.

I honestly kind of like Kagha, too, if only because she's edgier than Halsin. I've always disliked him, even back in EA. We could do with more druid elf Karens willing to kill children who think they're being righteous.

Us is really cute smile

That one Gith Doctor who tries to lobotomise us has a great voice, I loved her.

Valeria's a goofy drunk corrupt cop but she's also a small elephant with big wings for ears and a monocle and a pipe. What more could someone ask for?

Yurgir's such a bro. What a good lad. Hope he's doing well in the Avernus wars or whatever.

Lucretious is fun, and that one imp she has that's married to a stone golem.

That one Dragonborn pissed about the newspaper puzzles is certainly striking.

I'd have to think of more minor NPCs...

I'm not huge on Abdirak, but I think he might've originally had something else going on in act 3, considering he got his very own unique head mesh. Weird he'd get one while other more important characters did not.
