Idolaf Battle Born. He makes an earthworm looks intelligent.

The female Imperial captain at the start who says words to the effect of: "You're not on the list, so what? Go to the block anyway."

Nazeem. 'Nuff said.

Jarl Balgruuf's brat who says: "Another wanderer here to lick my father's boots, good job."

Proventus Avenicci, or Wormtongue as I like to call him.

Thalmor. Why? I'd like to think so I can courier their pointy ears back to their families, but I'll settle with the fact that they irritate me. It's not so much High Elves, just Thalmor.

Necromancers. Why? Well, if they like to groove out on dead things, then they can join them instead of vice versa.

Nazeem. Why? He's a door handle.

My Nord warrior Bjorn has a couple:

/RP on

Ulfric Stormcloak - killed his family in Markarth during the "Markarth Incident" by claming they were Forsworn sympathizers. At the time, Bjorn was a young stable hand working for the Imperial army in Cyrodiil. He was orignally told that a group of thugs broke into his family's home and killed the inhabitants before plundering their goods. Later in life he found out the true story from a fellow Nord who hailed from Markarth... and now Bjorn has returned to Skyrim with a mind for vengenace.

The Thalmor - while acting on one their first missions purging Talos worshipers out of the Empire, they stumbled across Bjorn and some of his fellow Nords in prayer. They immediatley accused them in being in violation the White-Gold Concordat. They didn't find any proof of it, yet they decided to make it a point that no man had risen to become a God... and thus took a white hot knife off the fire and carved Bjorn's cheek with it. Bjorn has never resented the Elves in his life, until that day.

The rich people. They don't know [censored] about marxism and need to be educated.

When playing as my non-exploited mage (hardmode) I find myself plotting the extinction of Sabercats across Skyrim.

Thalmor: They're just hateable. I kill every single one I find.
Children: If it weren't for their dialogue I wouldn't even notice them. However, when they insist on "mistaking" me for their hired help, or that they'll "go easy on me", it makes me rage.
Vigilants of Stendarr: They've all got a screw loose. I don't like crazy overly religious people of any sort.
Daedra: Don't like them either. Creepy, repugnant things always looking for ways to screw people over. It's a shame I can't set their shrines alight when I see them.
The Dark Brotherhood: I've hated them since Morrowind. They're a bunch of nutcases in a murder cult. Doesn't help that they try to kill me in every single game.
Stormcloaks: A bunch of shortsighted fools. Any sympathy I might have had for them disappeared when I learned more about Ulfric and his "cause". I also don't appreciate having people wave a battleaxe in my face just for wandering by.

Pretty much all my characters hate the Thalmor, Ivory is most likely their biggest foe since she got some hired Thalmor assassins on her back more than one time.
Annette has a hate thing for the Vigilants of Stendarr. Rosarot is a slaughterfisher and an enemy of the Empire.
Tasha doesn't like people who think bad of her fellow Khajiit. Sick, sick people.
Faeron wants everyone to be blessed by Sheogorath and live in peace, with cupcakes. Even mudcrabs.
