Volo is fun. He's what I consider the quintessential Bard. Loud, funny and... Not very good at things.

Khaga. Most Druids in the game make Druidism feel like some sort of hippie cult. Khaga brings into things the Shadow Druids, dealing with moral dilemmas between protecting sacred ground and helping others and her own repentence. I honestly wish she joined our party instead of Halsin... Make it her penance where she has to go with you and reflect on her actions. I'd imagine her seeing the Shadow Cursed Lands in person would be a significant shock in regards to her decision to embrace shadows.

Lump. An articulate Ogre isn't something you see every day. The contrast of brute force and base instinct of "Just eat everything" and the intellect and spell casting he has is neat (Also cool to see that the reason he's so smart is because of the headband he's wearing). Shame that he won't follow you outside of Act 1 and that killing him for his headband is too good to pass up... I wonder how he'd react to the player licking the Spider corpse in Act 2?

The Monk Spirit from the pendant. A very minor character, but interesting nonetheless. Kind of want to see how a conversation between him and Volo would turn out honestly...
