The Alien (also known as Xenomorph or Internecivus raptus) is a fictional endoparasitoid extraterrestrial species that is the eponymous antagonist of the Alien film series. It appears in the video SMG4: The Movie Audition, SMG4: Mario Raids Area 51, SMG4: Wario Tries To Stop Himself From Dying and SMG4: Mario The Supreme Leader.


The Xenomorph seems to be a normal Xenomorph warrior, but unlike other xenomorphs, it is holding a crowbar.


When Steve offers a Koopa Troopa a chocolate, saying the famous Forrest Gump line " Life was like a box of chocolates.", the Xenomorph pops out of the box and roars in rage before attacking the Koopa Troopa, seemingly killing him, whilst Steve admires the Troopa's shoes.

Grid from Alien vs. Predator appears in SMG4: Mario Raids Area 51, but gets shot by Mario.

Drone Xenomorph returned in SMG4: Wario Tries To Stop Himself From Dying, when it clogs Wario' Bros.' residence toilet.

Chestburster-sized Xenomorph appears in SMG4: Mario The Supreme Leader when its host Mario checking the lake, Mario drinks the water with Xenomorph embryo, it bursts Mario's abdomen and later Mario throws it to the lake, causing it drowned.


It can be presumed that this xenomorph is no different from the others, intending to kill anything that proves a threat. However in SMG4: The Movie Audition and SMG4: Mario Raids Area 51 instead of using its natural weapons, Drone Xenomorph and Grid use a crowbar. This could mean they might be smarter than other Xenomorphs.
