|Powers and Abilities|
|First Appearance||New Chess Pieces (episode)|
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. He can also mimic the voice of those he imitates, being a perfect disguise. His other powers are stretching and regenerating powers, like Lucy.
He can shapeshift instantly upon transformation, making himself look like whatever he wants right away.
He can be killed by being thrown into water, by extreme heat, or by being frozen and shattered. He is weak to lightning. Extreme heat causes him to rapidly harden, but he has enough time to shift to a different alien, a fortune other Sludges don't have.
