They have been defeated by humans so many times, one wonders how adaptable they actually are. It would be really creepy if they actually changed strategy and tried something like diplomacy. Three dimensional villains were always the best. Think of this, they establish an embassy on Earth, and offer free, non-individualism-killing implants, or collective consciousness tryouts. It'd be really freaky if people actually started joining them of their own volition. Ooh, and that gives us shades of gray, gotta love them! Dunno where I'd go with that story, but it'd be a fresh new take on the worn out cyberzombies.
