In Aliens, Private Jeanette Vasquez (Jenette Goldstein) is a smartgun operator who’s sent by the Marine Corps to deal with a space colony’s Xenomorph infestation. She’s tough as nails and doesn’t take crap from anyone, a useful skill when you’re in the same squad as Private Hudson.

In Vertigo, Madeleine Elster (played by Kim Novak) fears that she’s been possessed by her great grandmother who committed suicide. A retired detective is hired to secretly tail her and make sure she stays safe, but he doesn’t do such a great job when his fear of heights comes into play.

Grouchy and sarcastic, Gaz has very little interest in her older brother’s plans to out Zim as an alien. She would rather be playing video games and eating pizza like most kids her age. Though, she’s technically not considered goth, her style definitely leans toward the darker side.

In the Alien series, Ellen Ripley (Sigourney Weaver) is a warrant officer aboard the spaceship Nostromo. When the crew wakes from stasis to find an unknown creature has infiltrated the ship, Ripley steps up to play the unlikely hero.

In Invader Zim, Tak’s main goal is to prevent Zim from completing his mission to destroy Earth. She holds a grudge against him ever since he inadvertently sabotaged her chances of becoming an Invader.

If there is one thing to say of Dib, it’s that he has determination. He’s obsessed with the paranormal and self-conscious about the size of his head. Wearing a trench coat and a hairstyle that likely requires a lot of pomade, Dib is extremely unpopular in school. But who has time for popularity when there is an alien to catch?
