Alien

This unidentified individual appears in the The Missing Nickelodeon Cartoon.

The Missing Nickelodeon Cartoon
The Missing Nickelodeon Cartoon opens with TheGamerFromMars being chased by the alien until he hides in a basement and finds an axe. He goes after the alien and right when he is about to kill him the video cuts to black and TheGamerFromMars begins talking to the camera. We later see him cleaning the axe so it can be assumed that he is dead.
