ORIGIN:
A strange creature that appears only when anybody tries to build anything within a very specific 500-meter radius, and utterly destroys whatever is being constructed. When it is not active, Ononobi exists as micro-organism. It was left on the planet millennia ago, to constantly keep clear the site of a future alien spaceship landing.
ABILITIES:
Hyper Cleanup: arms can quickly remove all material from the designated landing site
Whack Tail: tail can enlarge and be used to knock away opponents
Micro-Size: when not in cleanup mode, exists as a micro-organism
