The Alien is an enemy found in the Pixelated World level Area 52. It also had three advanced versions found in Crossed Worlds at the Space Station. There it will be wearing spacesuits while holding weapons. These weapons seem to be the 0xbadc0de, the Dark Force Saber, and the Alien Gun. It also has an armed version where they are holding the Alien Gun in Area 52.
The Alien is a small alien with two large blue-tinted eyes, an extremely small mouth, green skin, and a head that is slightly wider than its body.
The Alien will run at the player, covering ground surprisingly fast. When attacking the player, it will raise its arms at a 90-degree angle. Once that happens and the player is within its reach damage will be dealt with the player. Some aliens are armed with Alien Guns. An armed alien will walk much slower than an unarmed specimen.
