Name of Technique: Mizukurage (Jellyfish Water)
Type of Jutsu: Nin/Summon
Rank: S
Range: N/A
Nature Type: N/A
Description: In Sage and normal mode Heihachi uses his most infamous jutsu, Mizukurage. When Heihachi uses any water based technique or free body of water he manipulates. He then summons and incorporates very small microscope sized jellyfish in his water undetectable by the Rinnegan and the Byakugan, but can be seen by the Sharingan. Heihachi then whips around his water or cast his jutsu, when contact is made the jellyfish sting the opponent in a very subtle manner. The opponent will feel a sharp pain from the water, but cannot fathom the source, once they feel the pain the venom will have been implied.
Weakness: Cannot be used in boil release, and can be extinguished with other jutsu like Katon. The jellyfish need 100 stings to inflict a minor dosage of the poison resulting in welts and such. 200 are needed for a normal amount which is excruciating pain. 500 are needed for a potent/kill dosage, each hit generates 10 stings.
====================
Name of Technique: Shokushu (Tentacles)
Type of Jutsu: Ninjutsu
Rank: S
Range: 5-10 meters
Nature Type: Senjutsu
Description: Like a Jellyfish Hiehachi channels his chakra into his body to create several protruding jellyfish tentacles (8-10) that run adjacent to his normal two arms. These tentacles are as durable as normal appendages on the human body and are connected with Heihachi’s mind. These tentacles are good for several purposes such serving as extra limbs used for defense and attack. What’s most intriguing is the tentacles can produce jutsu through them in conjunction with the jutsu the user is casting. The tentacles can sting opponents like a normal jellyfish, and also act as sensors as they have a network of nerves called nerve net, which is capable of sensing odor, light and other similar stimulations. This simple yet effective nervous system helps the jellyfish to respond with lightning speed, allowing them to perceive Genjutsu and break it immediately.
Weakness: Two posts cool down for the regrowth of limbs.
====================
Name of Technique: Turritopsis nutricula (Immortal Jellyfish)
Type of Jutsu: N/A
Rank: S++
Range: N/A
Nature Type: N/A
Description: This is Heihachi’s most powerful jutsu, when faced with utter death or fatal consequences it inherits the Immortal Jellyfish jutsu. The life cycle of a jellyfish starts as an egg followed by larva, polyp, eventually becoming a medusa. The user deteriorates into water as a clone does and is absorbed through the earth until it finds a large body of water; from then on the user takes the jellyfish’s lifestyle and goes backwards. The tentacles becomes a cyst(egg) and reactivates genetic instructions from earlier events and creates new polyp cells and restarts the life cycle reproducing polyp cells until it forms into a Medusa. This is called transdifferentiation, which is when mature cells become different kinds of cells such as a muscle cell becoming a brain cell etc… This process can be repeated indefinitely .
Weakness: Heihachi is reborn into a small child.
====================
Name of Technique: Sasu (Sting)
Type of Jutsu: Nin/Tai
Rank: A
Range: Supplementary/ 10 feet
Nature Type: Senjutsu
Description: Heihachi coats his body in jellyfish stinging capsules called cnidocytes that appear as small jagged spikes. These have nematocysts, which has stinging mechanism with venom inside. When the opponent comes in contact with the skin they are met with these small jagged spikes, once contact made the stinging mechanism is activated. The spikes shoot nematocyst filaments into the body of the prey like harpoons. Once these filaments stick to the prey, they release venom, which paralyzes them. Heihachi can also gather chakra into his body and expel the spikes all at once. A barrage of hits is enough to inject a potent amount.
Weakness: Contact
Types of Venom.
Stings leave an intense, stinging pain, itching, rash, and raised welts. Normal amount of poison.
Box Jellyfish – Can initiate Cardiac arrest within 3 posts if the sting is potent enough. The tentacles stick tightly to the skin and may continue to release venom if not treated correctly, making things worse. Severe stings can lead to necrosis of the affected. The severity of a sting depends on the size of the box jellyfish, the amount of tentacles involved, the size of the victim, but also on the sensitivity of the skin of the victim.
Irukandji Jellyfish - Nausea, vomiting, abdominal pain, numbness/tingling, and muscle spasms. Severe pains at various parts of the body, typically excruciating muscle cramps in the arms and legs, severe pain in the back and kidneys, and a burning sensation of the skin and face.
