  • The weakness is earth, then fire.
  • In Rage Mode the back turns partially more blue.
  • When exhausted it fails to use its (water) air ball attack.
  • Asscernavesi can suck in much air that enables it to stay a long time underwater.
    • The Neopteron swims by using its arms and legs.
  • The body color enables perfect camouflage underwater.
  • With the wings the monster can produce a whirlpool underwater and whirlwind on land though it leaves water only when low on air.
  • It uses water and wind with a water air ball and the whirlpools.
    • On land these attacks are reduced to only wind moves.
  • The red color of the catch legs is used for luring prey in the deep sea. With the gluey substance it can hold prey and enemies.
    • The substance on the hands is a wanted glue for armors because it withstands even strong attacks and is water-proof.
  • Asscernavesi feeds of fish and smaller water monsters but also the monsters unawarely coming too near to the water.
  • They are loners normally but don't dislike the nearness of other individuals.
  • About the mating itself is not much known. Asscernavesis seem to go further in the sea to mate and seem to get quite deep in the water even. It's unknown why.
    • The females lay the eggs into certain underwater plants.
  • Breakable parts are the catch legs (each), the wings and the head.
    • When the wings are broken its whirlpool (-wind) attacks lose strength.
