Lunus

Lunus is an enemy only found in Kid Icarus: Of Myths and Monsters. It is a fanged sphere that shoots at Pit, with the ability to fire at most angles. Lunus prefers to stay in one place and bombard Pit with projectiles, and it can pin him down if he's not careful. Before Lunus spots Pit, it'll float vertically, looking like a waxing moon.

"An innocent-looking new moon that will attack Pit when it finds him."

Trivia

 * Lunus is likely based on Men, a lunar god that originated in Anatolia. Men existed in Roman mythology under the name Lunus, which was apparently the Latin version of his name.
