Sludge Blob

Sludge Blob is an alien that first appears in John Smith 10: Phantom Watch.

Appearance
Sludge Blob is a purple blob made of sludge. He has small green eyes, and has the Omnitrix symbol on his chest.

Powers and Abilities
Sludge Blob has the ability to shapeshift, and to look like anyone that he wants. This makes him different than other shapeshifting aliens, as he can disguise himself as whatever he wants. His other powers haven't been shown yet, but he most likely has stretching and regenerating powers, like Lucy.
