Nemesis, from what I can tell in screenshots (never seen one in game as of yet), just appear labeled as any other mob. Would it not make more sense to actually have a special label for them, or is there already one?
I get after a while you’ll know them by name, but until then it’d be handy to know what you’re facing before it slaps you to the ground.
They are the only enemy in the game with a blood red text color for their name. And after you meet one the first time you won’t forget it 
ahhh fair enough then, I will keep my eyes peeled.
As I said, I have not met one yet and am not wanting to just accidently blitz into one.
Thanks for the reply
you won’t see them until you hit nemesis status with the associated enemy faction.
Also, once you get killed by one, you’ll never forget it. Lol, especially when one is among the enemy mob.
“What the hell is hitting me this hard? Oh lol…Nemesis”
Yeah I knew this, I started to get worried on ultimate, after reaching Nemesis with all but Cronleys gang, because I often just blitz into groups of mobs. I started wondering how I would be able to tell Nemesis from hero’s.
Probably not as I play on HC 
hence the panic of blindly running into groups of mobs without checking for Nemesis. I am now being more careful and scout groups before rushing in.
The other nice thing is you will not often than not see the nemesis chest before you see the nemesis, which is obviously a clue 
also three of the five nemeses are very large and very unique looking
That’s good to know then. Although I am still anxious about facing one. Don’t think my lvl 82 could handle one yet.
The Aetherial Nemesis and Undead Nemesis aren’t that hard if you know how to kite them.
Fabius on the other hand, well… Let’s say I think he is tougher than Ultimate Log.
