With playing my wii again I have to hand it to Nintendo to make shitty enemies, the turtle things and mushroom things from Mario, the Rabbids from Rayman, Lego star wars, 1/3 enemies from pikmin. The list goes on and on. Anyhow name off a couple of shitty bad guys in the work of god.
The Husk from ME3, in ME2 if there was more than 5 at once you were so fucked if you had to reload. Now in ME3 they are 1 shot kills with a pistol.
Come now, radroaches and molerats weren't that bad in FO:3. The former was cliche, yes, but the latter wasn't that bad. In FO:NV, they did suck though. Neither appeared enough for people really to take notice and they were pretty random and annoying.
Creamboat Creations in The Movies. Every army in CoD, which presumably have all lost millions more troops than they possibly could have in reality by now. Milan and Venice in Medieval II: Total War. The Crimean Khanate in Empire: Total War. Kai Leng. Because 'omg, Kai Leng is here!'
