Breakfast Topic: Who is your NPC buddy?

I have an incredibly soft spot for Wrathion. Heck, I helped him avoid being smushed as an egg. And then later, I happily murdered his brothers and sisters as well as his utterly cuckoo father. He was so impressed he gave me awesome daggers, even. And sure, I mean, he's a member of the Black Dragonflight and likely using me for his own nefarious means, but I just like the kid. He's my buddy.

Needless to say, I was utterly delighted to find him in Pandaria. I was even more delighted when he was finally given something to say and decided to say hello to little old me. I mean, I'm sure he's got other master assassins kicking around, but I'm his favorite. So I'll happily do whatever he asks. He's cool. We're on the same wavelength — for now, anyway.

I seem to get this with every new expansion. Out of all of the varied NPCs introduced, I find one who strikes a particular chord within my heart, and they are my friend forever and ever. Mylune, Stormcaller Mylra, good old Jones in Dalaran (aka the best kitty ever), Rexxar, Umber — the list goes on and on, and there is no rhyme or reason to it. In Mists, Lorewalker Cho is an immediate favorite, as well as Li Li and of course Chen Stormstout. Who doesn't love Chen?

I can't be the only one who does this. Is there any NPC you've got a particular attachment to? One who makes you smile every time you see them? One whose quest you don't mind repeating on endless alts — one whose quests you actually look forward to repeating? Let's have it — who is your NPC buddy?
