–Yasumi's transformation announcement

Exodus Goop.

As Goop, Yasumi is indestructible, making it difficult to defeat her by attacking her body.

Yasumi is able to generate and shoot slime from any part of her body. The slime she generates can either be acidic or adhesive. She can shoot it in continuous streams similar to a water hose or in blob-like projectiles. She is even capable of spitting out either slime or acid despite having no visible mouth.

Yasumi is capable of making herself and her touch acidic at will. Her acid is also able to dissolve a large variety of materials.

Yasumi can stretch, bend and deform herself into any shape or form.

Due to being made of slime, Yasumi can hold objects inside her body. She can also do this with individuals to protect them.

Yasumi can produce multiple slime tentacles from her body to grab multiple opponents.

Yasumi can regenerate and rebuild herself with ease.

Yasumi possesses enhanced strength and can increase the impact power of her attacks by stretching herself backwards and using the recoil to launch enemies with a single punch.

Yasumi can breathe underwater.

Yasumi can change her density depending on her desire.

Yasumi can pass under an enemy's foot in order to make them slip.

Yasumi can stick and scale on walls without difficulty.

Yasumi can survive in intense heat.

Yasumi can mimic the shape of simple objects to fool an opponent.

Similar to Ghostfreak, Yasumi has movable eyes.


Yasumi's Anti-Gravity Projector allows her to change her shape, form, length, width, and height at will, as well as granting her the ability to fly and levitate. If Yasumi loses his Anti-Gravity Projector, the Goop DISK can immediately generate a new one.

Yasumi can control and launch her Anti-Gravity Projector at enemies to attack them due to the edges of it being razor-sharp.

Thanks to her Anti-Gravity Projector, Yasumi is capable of high-speed flight.


Yasumi is limited to her Anti-Gravity Projector controlling her body. If it is separated from her by more than two feet or turned off, Yasumi's body collapses into an immobilized puddle until it recollects it. She can only struggle to move since she cannot change shape or make appendages to move without her Anti-Gravity Projector.

Yasumi's Anti-Gravity Projector can be disabled by a shot from a Positron Blaster, which makes her spin around extremely quickly and then separate into multiple parts.

Yasumi can be hurt if she is spun really fast in a centrifuge, which will cause her to begin separating into her constituent compounds.

While running, Yasumi is not very fast and cannot outrun humans.

Yasumi cannot regenerate if she is being continuously attacked.

Yasumi is vulnerable to suction.

Yasumi is vulnerable to being hypnotized.
