Limax's are semi-humanoid blobs, mostly brown/green in color with dirty pink organs. They have multiple eyes, and they are shown to have no definite appearance, often having extra arms, fin-like protrusions, or mis-shapen body parts. They also like to eat humans, especially elderly, saying children are too chewy, and need to grow older to become "nice and tender".
Limaxes are able to shift into any form, including human bodies. It is shone to have transformed into Grandpa,an old man,etc. They also gain strength from heat, as shown when they are attacked by Heatblast. This is the reason they decided to attack a retirement area in the desert. They can also regenerate, and in doing so (sometimes), they create a much larger version of themselves, that seems to speak more than the others to.
Limaxes are deathly afraid of water. Even just a tiny bit of water may injure or even kill them. This may be because their bodies are mostly liquid, and water interfering could melt them away.
