I recently ended up witnessing the argonian guards in stormgate pass fight random enemies that followed me into town a couple timed, and i must say, Morrowind argonians have some great voice acting, especially in combat. Their hissing is genuinely intimidating and the emotionless way they go "kill." really emphasizes their alien, expressionless nature
Shame no one really knows about it since I'm pretty sure there's less than half a dozen scenarios in which you can end up fighting argonians in vanilla morrowind unless you're going out of your way to slaughter slaves, and not that many morr in TR either
