Zeiram

A Japanese Sci-fi film in which an unkillable alien creature (Zeiram) arrives in on Earth (landing in Japan, naturally). It is followed by Iria, a female bounty hunter from another planet who has been pursuing Zeiram. Upon arriving, Iria, Zeiram, and two electrical workers are drawn into an alternate dimension where they only have a certain amount of time to kill Zeiram.

Zeiram was followed by a sequel, Zeiram II, as well as an animated prequel, IRIA: Zeiram the Animation, which depicts Iria's first encounter with Zeiram.

This film and its followups contain examples of:

 * Action Girl - Iria.
 * Alien Lunch - Teppei eats a cockroach, squicking Kamiya heavily.
 * Bifauxnen: in the animation.
 * Bounty Hunter
 * BFG - The cannon that's used to defeat Zeiram's  final form
 * Cool Mask
 * Enemy Summoner - Zeiram; also crosses over with Cloning Blues and Mook Maker when it spawns a whole army of biological weirdos in the animation.
 * One of the funniest moments in the movie is when Zeiram summons an enemy... who ends up just being a puddle with a head and half of a torso. Zeiram grunts at it while pointing forwards, and the two argue in an alien language, presumably about how the puddle literally can't do what Zeiram is telling it to, then Zeiram facepalms and stomps on it.
 * Everything's Better With Bob
 * Healing Factor - Zeiram... kinda;
 * Hero Killer: In Iria: Zeriam The Animation, Zeiram kills her brother Glen.
