Crabstacean

 is the Omnitrix's DNA sample of an unknown species from an unknown planet in Earth-1010.

Appearance
Crabstacean is a small, crab-like alien with a dark red-ish shell. He has two small rear legs and two powerful claws acting as its forelegs. He has large mandibles and round green eyes.

Powers and Abilities
Having seen these aliens himself before, Ben already knows this alien's powers before using him.

He has powerful mandibles and claws, both capable of crushing and tearing through steel with ease. His shell is equally as strong.

Crabstacean has a large appetite and is not a picky eater, able to eat many inorganic substances and quickly.

Although not something Ben new beforehand, Crabstacean can breath underwater- hence the presence of the civilians on Aquillis that were scanned to unlock this alien.

Weaknesses
has yet to appear in-series, so Ben has yet to learn his weaknesses.

Ben 10: Road Trip
Crabstacean was one of the many alien species scanned by the T2 Omnitrix in Tides of War, and is the only alien currently scanned into the Civilian Playlist. He was used to hide from a squad of Teslamorpha Electroviles that had been chasing Killermari.
