Easily one of my favourite aliens right here, the poses you can for him are literally endless, but I can only one for pile of slime himself, GOOP!!!

Goop is the Omnitrixs DNA sample of a Polymorph from the planet Viscosia.

Abilities

• Gelatinous Physiology - Goop is a 200 pound pile of slime that, with the help of his Anti-Gravity Projector, can stretch, bend and deform himself into any shape at will.
• Slime Generation - Goop is able to generate and shoot slime from any part of his body. Either in continuous streams or in late blobs for acidic and adhesive effects.
• Acidic Transformation - Goop is capable of control his PH level and thus make himself acidic. Melting and dissolving and large variety of materials.
• Flight - Due to his Anti-Gravity Projector, Goop is has the ability to fly and levitate at fair speeds.

Weaknesses

• Anti-Gravity Projector - Goop is limited to the projector controlling his body. If it is separated from him by more than three feet, Goop's body collapses into an immobilized puddle until it recollects it.
• Seperation - If fast enough, someone can repeatedly seperate Goops body faster than his projector can pull it back together, thus immobilising him.
• EMP - If Goop's projector is struck by a strong electromagnetic pulse, it will shut down and leave Goop in a puddle until it's activated again.
