These key limitations seemed a bit limiting (sorry for repetition) in the AE:
a) A custom critter is only able to access two powersets, yet in the game critters, many possess powers from 3 or 4 sets.
b) Custom critters are disallowed access to Power pools (including Epic), yet in game many NPCs have pool powers (not including flight), especially leadership and concealment.
c) No brawl? Many NPCs have a simply brawl, zombies have their own zombie brawl.
What I have done is compiled a list of all NPCs who have more than 2 powersets, and pools powers (no list for Epics, lost my patience).
All this information comes from Paragonwiki.com, very little comes from me.
Enemies with 2+ power sets (sorry for abbreviations, me=melee, ar=armor, b or bl=blast, c=control, man or mani=manipulation):
-I excluded auto regeneration; all praetorian clockwork and vampyr have fast healing.
-Some power sets have been assumed (i.e.: Clockwork plasma attacks can be considered energy attacks)
- When there is a sub-NPC (see Vampyr) that means "the same goes for", same sets not same powers.
