Khost is an alien ghost in a form that somehow resembles paper, usually controlled by the Vortaak, he doesn't contribute much to the Earth. He is very intelligent and aware of danger, and when he's not being controlled by the Vortaak, he is normally in Earth visiting Monster Island, and sometimes when he's relaxing down here, other monsters attack and he helps the Earth Defenders defend our planet from them, so sometimes he's said to be an Honorary Earth Hero.
- Khost's original name was Ghostly, but it was changed.
- Ghostly was a normal looking ghost, but his appearance was changed to the current one.
- Ghostly could turn into lots of things, but all made of slime. It was scrapped.
- Ghostly was a Mutant, unknown why, since he's an alien ghost. He's at the Alien Faction now.
- When Ghostly was killed by Mecha-Cobra, he was revived, with his old body, but parts of his body had changed, the differences are: sharp teeth instead of no teeth, his heart is visible, the hand on the heart's side is dried up, his tongue is longer and he's bigger.
- Khost had two giant horns on each side of his head, but they were removed.
