So if I was a supervillian, I'd have little robot minions of course. I'd take over Utah first since they are close and I don't want them throwing fits. Then I'd make robot dragons and take out Germany, cause with their track record I don't want to smurf with them. THEN I'd just start taking out a bunch of countries with my robot minions.
If you had a PHD in horribleness... tehee.... what are your world domination plans?
