A chojin with an octopus design.
Tentakors is a Justice Chojin that is featured during the Chojin Ittosai in Kinnikuman Nisei ~All Chojin Dai Shingeki~. He is first pitted against Tokku, whom he defeats, and later he fights Mantaro Kinniku in the semi-finals, but it defeated by a Kinniku Driver. His special power is penetrating the body of his opponent and exploding out, typically killing them in the process.
At Yokohama International Stadium, Tentakors arrives at the "Top Chojin Festival".  The first test of the preliminary stage is a set of monkey-bars elevated very high, which are greased to make it difficult to stay in place.  Tentakors succeeds in this preliminary match and is one of the eight finalists to compete in the festival.  When picking their place for the match-ups, Tokku picks ball number eight, which means he gets to pick his place in the match-ups very last.  Being last place, Tokku is forced to fight Tentakors. 
The fight takes place in the underground food hall of a shopping mall. 
The ring is placed inside a giant bowl, which is cooking kombu soup, and the loser will be thrown into the soup and lose their life. Tentakors attempts a Powerbomb, which leads to Tokku being flattened against the mat. Tokku soon counters with a Mochiyah and tosses Tentakors into the soup.  Tokku worries about Tentakors, where the remains of Tentakors seem to simmer to the surface.  An octopus pot blasts towards Tokku, before it sprouts legs and it is revealed Tentakors hid inside the pot to avoid being boiled alive. They exchange a series of blows, until Tentakors camouflages with the canvas and commits a Dragon Suplex. 
Tokku is then tossed towards the soup, but holds on with his legs to the ropes, and then counters with a Tokku Body-Coil. Tentacles - at a disadvantage - throws his pot towards a boy in the audience, which forces him to use his body as a shield to protect the boy in question. Tentakors then spins Tokku around in a circle, to drain all moisture from him, which turns him stale and make him go hard.  When Tokku is weak, Tentakors forces his way deep inside his body, before bursting out in multiple places and tearing him open from the inside. After committing enucleation, he explodes Tokku into multiple pieces. The pieces of his dismembered body fall into the soup to be cooked. 
The placement for the semi-finals are decided by rock-paper-scissors.  Tentakors is forced to pick 'rock' due to only having tentacles, and so Mantaro Kinniku jams chopsticks into his flesh, which allows him to use 'scissors' at last moment. Together, they choose platform one. The match will take place at Shinbashi Station, where the ring is made of a takoyaki tray.  A flame is lit beneath the tray, while the holes are filled with dumpling batter, and various ingredients are dropped into the batter. The losing competitor will be used for the meat in the takoyaki. 
Mantaro is thrown first into the batter.  Sunshine and Ikemen Muscle start to shake the tray, which makes it harder for Mantaro to escape, but - as the takoyaki is complete - he frees himself from eating his way out of the batter. The holes are refilled and Mantaro tries to throw Tentakors into the mixture. Tentakors uses his Mimic Body to hide as a corner-post, which then flies out to strike Mantaro. Tentakors then pretends to be beef teriyaki to get inside Mantaro's body.  He gets fully inside Mantaro's body via his mouth.  Tentakors is unable to explode outward, as it is revealed Mantaro has a layer of dirt all over his body (due to not bathing or washing within the previous six months due to a hatred of baths). 
Tentakors - in disgust - flees from his body. Mantaro takes this opportunity to use his Kinniku Driver, propelling Tentakors into one of the holes filled with batter. He is baked into the batter and expelled from the ring, but Mantaro stops the audience from eating Tentakors by claiming he wishes to eat him as the victor.  Later, due to Mantaro saving him, he is able to burst forth from his dumpling.  Tentakors then provides commentary and information on the Kevin Mask and The Doomman match.
