2.
A machine built by the resistance from stolen skynet technology. its primary function is to destroy the vaginas of women who will give birth to the creators of skynet. Its exterior resembles that of a male underwear model to seduce women only to completely destroy their vaginas in bed using a multitude of tools and abilities.
the vaginator was sent back in time to stop skynet from starting up, and thus preventing the end of the world.
