Bandits. Wolves. Military Deserters
Basically, whatever isn't much more than a basic damaging attack and an HP pool (and maybe some very limited tactics).
This, of course, is all about reasonable enemies that the party is expected to be able to defeat. If you want to throw a 'fuck you' at em', the sky's the limit. Even if you aren't being uncharitable, you could probably still get away with a strong enemy by knocking down its most potent tools with some justification (just got away from a dangerous fight, cursed by an evil wizard/god, weak after a time period in hibernation/torpor/hell, et cetera).
