Wormhole

Wormhole is a Schwarzschildian from Schwarzschild and is an alien who can create a portal from his mouth into a region in the Null Void called the Schwarzschild Point.

Appearance
Wormhole is a fourteen-legged wormlike alien with its mouth oblong-shaped on its chest, with one green eye, sharp teeth, and the Ultimatrix symbol under its belly.

Abilities
Wormhole can suck like a vacuum virtually anything no matter what its size is into the portal. This portal leads to a region in the Null Void unaccessible anywhere else: the Schwarzschild Point. Every time something goes into the portal, it serves as "food" and gives energy to the alien depending on how much it took. If it's "full", Wormhole can use his eye and shoot laser beams.

Weaknesses
Wormhole can only open its mouth for a short time as it cannot suck too much amount of matter, even though it can virtually suck everything. If a powerful alien is sucked in, that alien might escape or be deliberately vomited by Wormhole.

Ultimate Wormhole
Ultimate Wormhole is a longer form of Wormhole and is blue with a more powerful laser beam and can suck more matter into it.

Trivia

 * The name of its species and planet (Schwarzschildian and Schwarzschild) came from an actual scientist who was involved in knowledge of wormholes.
