The Dog Queen is a Xenomorph that appears in the Alien3 video game released on the Super Nintendo Entertainment System. They are essentially a Queen grown from a Runner Alien, looking similar but considerably larger. They spit clouds of acid smoke and live on the surface of the planet Fiorina "Fury" 161.
In the description for the mission in which they appear for the first time, it is said that they are attempting to create a new Hive outside the prison colony. The player must prevent this from happening by killing them all.
