Don't worry, the party runs wilder now XDAs I said before the difference between a Drone and Warrior is not their head domes, as so many tend to believe, but their mannerisms and color. Drones are workers and Warriors are warriors, and they act according to their role.Warriors have been proven able to have smooth domes as well as ridged ones. First seen in AVP. Grid alien and it's other Human-spawned siblings have smooth, black domes all throughout the movie. Never once is a ridged Alien seen.In the 2010 Aliens vs. Predator game, a skin called "Warrior Dome" depicts a warrior with a smooth black head. From this it can be assumed the type of Dome an Alien has depends on that individual Alien. Presumably, this warrior was based on the Aliens in AVP, like Grid alien or possibly the Alien from the 1979 Alien movie (In terms of it's dome structure).So that, it's my own alien appearance'cause there aren't a standad appearance for warriors and drones.
