You read right, what enemy in a game do you despise with a passion? Mine is from Xcom Enemy Unknown, I cannot remember its name so I hope the description helps. This enemy is so overpowered that I would rather be up against ten Mutons than one whatever the hell it is. Even worse is it pulled a fast one on me when I first encountered it. The thing spawned a drone so I thought, 'okay, no biggie,' before being crushed by it. Worse still, all the maps I have encountered it on have forced my soldiers to bunch up and get taken out on mass by it. Also it has attacks that all do AOE and can attack twice in the same turn.
Captcha: only way to be sure. I agree captcha, nuke it.
