What's your favourite enemy to fight? For me its the humble bandit, preferably a chief. Nothing beats a good old fashioned sword fight.

Bandits. Easy and fun to eliminate.

Thalmor or Draugr.

For me personally it's any un-dead, drugar, vampires, etc...

Using holy spells this can be very entertaining.

I like to kill thalmor, dragons, dragon priests, pirates,imperials,gen. Tullius', Legate Rikkes, and people who ask questions about who they want to fight. Just go with the flow and kill everyone that doesn't follow your judgement. Lydia has been acting traitorous lately... She doesn't want to carry my burdens!

I like Hagravens and Dragon Priests.

Bandits. Their classic lines are humorous.

Victory or Sovngarde!

*after a few hits*

Death is highly overrated!

Or (when in werewolf)

Die already so I can take your stuff.

*doing the pounce/clawing them up deathkill*

That all you've got?

*when arriving/leaving an HF home*

Bad time to get lost friend,

*sigh* Without Skyrim, the game would be boring

Dwarven Centurion Masters.

You can't beat a good old-fashioned sword-and-bow-wielding Skeleton for being the ultimate last word in classic fantasy roleplaying enemies, in my book.

Definitely Bandits. It's quite satisfying ridding the world of its garbage. Lockpicks are always useful. I too enjoy their ambient dialogue and pathetic taunts. Plus as human enemies they're worth some good killcams, and there are plenty of them.

The Almighty Bear.

After that; giants, draugr, sabre cats, were-beasts, and - YES THAT'S RIGHT - dragons.

Also @killer_rabbit: I absolutely dig your post. Made me lol.

legion soldiers

Not gonna lie, with 200 souls absorbed, it the dragons. I will wait 3 days to refresh their lairs and go kill them again..

Anything made of meat, basically. I have mixed feelings about mages, I find them annoying to fight but extremely satisfying to kill. I guess weak mages are my favourite enemy. Even better clearing a fort of them.

Bandits, mainly because I love eavesdropping on their conversations before I kill them.

Any undead creature!... die already for [censored]'s sake!

Frost trolls are fun to fight at a low level

For me the best actual battle in the game is against Karstaag, it's always epic and quite satisfying when you finally take him down.

Giants are funny chasing me around obstacles. Draugr lords are very cool especially when they use shouts.

Dragons will always be my favorite, simply because I love how they go airborne on us.

Runner-up: Briarhearts and Hagravens.

They're the only two NPCs which can actually put up a decent fight.

Mine is Stormcloak traitors!

atleast I didnt say wimperials or (w)imperial traitors.

My favorite? Spiders, and that includes the dwarven ones, too. Nothing with that many legs deserves to live.

Skeletons. Love blasting their bones all over the place. Such satisfaction.

Named Thalmor.
