Void-Eater

Maybe the strangest of all Glooples, the Void Eater has much more mass than the Gray-Gloople, but instead of it, its really small. However, this strange situations grant him powers over energy and gravity; basically, it's a cross between a Gloople and a black hole.

Powers and abilities
A Void Eater seems able to alter its own gravity, but this ability is reduced to a slow float 1m above the terrain. Also, this creature can rapidly alter its mass: by reducing it, it can attract objects; by abearing it for a brief instant, it can generate a shockwave similar to a powerful explosion, destroying anything near it. Lastly, it can generate a powerful, black stream of pure energy. This beam can attract distant objects and cause them to make physical contact it, which results in instantly disintegration (possibly due to compression into a singularity).

It's interesting the fact that, when a Void Eater is hit, it will simply be splatted, and its powers will be nullified. Some have thought that the death of a Void Eater could result into the creation of a dangerous black hole, but luckily this was proven false.
