Not to be confused with Greg.


—Greg after being rescued from Area 51, SMG4: Mario Raids Area 51

Greg The Alien is a recurring character in the SMG4 series.

He is an alien who first appeared on SMG4: Mario Raids Area 51. He was captured by the FBI, but he was eventually rescued by Mario. In SMG4: If Mario Was in... Minecraft, Greg is shown to be "eating" spaghetti with Luigi right before it gets taken by the Enderman.


He is a green alien with black eyes.


While he is almost never shown speaking, he seems to enjoy Mario’s company. He may be dead inside since he never interacted with Mario when he first met him. However, at the end of the blooper, he gives a smile to Mario, showing that he is grateful to hospitality and friendliness.

It's later implied that he is a bit weird, as he somehow changes the Wi-Fi password at Mario's home. He can also be responsive from time to time, clapping Mario's performance at one point.
