The Blob

The Blob is an amorphous, gelatinous alien entity that was brought to planet Earth trapped inside a meteorite. Nothing is known about its origins, the natural habits of the species or how common Blobs are in the universe.

This creature has no definite shape or size, being able to change its form at will. It is very amoeba like in build. It quickly consumes all living things it can capture, growing more and more as it feeds. The Blob seems to be very fast and strong for a gelatinous organism that moves around by slithering. In the 1988 Incident, the blob was more intelligent, for it ambushed prey. It even trapped prey. The creature digested its prey chemically. The thing was originally transparent white, but grew dark reddish purple from the blood of its victims.

Although there is no known way to kill a Blob, it is known that the beast stays away from cold temperatures, as they cause the Blob to solidify. It is not killed, though, and it will come back to life once the temperature is raised again.

When the Blob comes alive, he tilt the stick downward to remove it, but the blob already awoken and attacked him by covering his right hand.
