The Alien (also known as Xenomorph or Internecivus raptus) is a minor character in the SMG4 series.
It 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 can take on many forms, but seems to have common traits, including an inner jaw, a long tail with a sharpened edge, a eyeless elongated head, and acid blood. Commonly, they start out as embryos, which are carried by a facehugger, hand like creature with 8 legs, a tail, and a mounth on it's belly, which it uses to impregnate a host. Facehuggers are usually contained in eggs, human-sized egg like structure with a 4 way opening. After a period ranging from 10 minutes to 6 hours, the chestburster, a small, snake like creature with similar features to an adult Xenomorph, emerges from the host chest. In cases where there is no queen present, a Xenomorph may become a queen, a larger varient of the xenomorph with 4 arms, a crown like appendage piercing out of the back of it's head, and a detachable sack, used to reproduce and create more eggs. The variants seen in the episodes seems to be a normal Xenomorph warrior or drone, but unlike other xenomorphs, it is holding a crowbar and can speak, showing a higher level of intelligence than average.

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.
