Asimov is the spirit you first encounter before you arrive in Xio. He tells you that you are the only one who can save the ancient land, and later on he gives you tips about items such as the Ark Seed and the Transmitter Fruit, when you enter the mines he says he needs a lie down and becomes a moon, attracting all gas from flowers. In this state he appears in level 1 and 9.
Asimov looks like a big, green, floating head with a smooth beard and hair.
- One of the costumes in the game is named Asimov's wig. Once you use it, the clone will gain Asimov's hair and beard.
