The most entertaining NPC in the saga

I want you guys/damsels to vote the most entertaining NPC in the saga in your opinion.

You can vote for any NPC be it Bioware, Beamdog or Mod. I will regularly check the topic to update the OP with the votes. I'll do it manually since you can only have 10 poll options.

Note: NPC "enhanced by mods" will still be counted as a vote for said NPC.
Edit: To avoid scattering votes, you can only vote for playable npc!
Stating why you vote for said NPC is most welcome.

NEW IDEA: Add your favorite quote (doesn't need to be 100% exact) from said character.

I vote for Xan thanks to the Xan friendship mod.

Baeloth: 1
Edwin: 2
Jan: 7
Korgan: 1
Minsc/Boo: 7
Neera: 4
Tiax: 1
Xan: 1
Xzar: 2
