The Mutant Jellyfish is like any other fish or aquatic kaiju. While it has no eyes, it is capable of 'seeing' with the barbed scent organs on the sides of its face (the two pink sacks). It has the intellect of an octopus, but is quick to flee from bigger threats.
- Acid Spit: It can fire corrosive saliva from its mouth.
- Hovering: It can hover above the water surface indefinitely, through unknown means.
- Swimming: It is capable of swimming incredibly fast.
- Despite his name, Mutant Jellyfish looks nothing like a jellyfish. in fact, he looks more similar to a prawn.
- It is actually supposed to have a shell like a Nautilis, but could not find one due to its gigantic size.
