The Tanaka Aliens's Boss is first seen on the second floor of an abandoned apartment building surrounded by Tanaka Alien Eggs and protected by the Apartment Tanaka's.


The Tanaka Aliens' Boss is a Tanaka Alien which seems to be an adult. If we assume they follow normal growing patterns. Unlike the others he doesn't wear a robot like Tanaka Shell to protect it, instead having some form of breathing apparatus with two tubes going into its mouth. It is assumed to always be in its true form due to its size since he is an extremely tall, muscular and has a large stature. It is an anthropomorphic bluish purple bird-like creature, that unlike the others has small narrow eyes and a far larger toothed beak, flaring nostrils and a beard looking thing under its beak instead of a ridge. It also has a pair of razor sharp talons as feet which allow him to jump very high and grab people. It has at least a 2 meter wingspan.


He was a Tanaka Alien (real name of race unknown) they are one of the alien species that fled a dying star system, starting 30 years ago. He may have been born here on earth having been raised watching the actual Seiji Tanaka in the seventies when Tanaka had a bit of real fame in japan and even abroad. He guards the species eggs before confronting Kei Kurono for grabbing his hatchlings and accidentally stepping on one.


It starts out ignoring Kei Kurono but then when Kurono grabs one of the Tanaka Alien Hatchlings and nearly fully steps on another it gets up and walks towards Kurono. It looks down on him with arrogance before bending its beak towards Kurono as if to show of its might and strength to Kurono. Whom is not impressed and threatens to shoot it then as the other Tanaka's starts firing on Kurono it joins them in releasing energy blasts upon Kurono showing itself very outraged at Kurono and meanwhile unable to fully oversee the situation unfolding in front of him as Kurono manages to shoot out the walls and the floor of the apartment allowing him to not only escape from the seven of them but also kill all of his fellows. Having escaped form the rubble of the apartment it blindly attack and kills the first human it sees before confronting a second with no care or thought about the fact he is landing in the middle of a group of potentially lethal opponents, it then sees Kurono and in its rage forgets all the others bulldozing them aside as he grabs Kurono ready to enact his vengeance upon him. Kurono however puts up a fight, managing both to not get his head bitten off and shooting at it, then in its overconfidence it forgets that his breathign apparatus is exposed which Kurono manages to grab making it lose control over its flying and forcing him to release Kurono who kills him as he falls. It showed itself to be overconfident and unthinking in its actions against the hunters leading to its demise. It would have fared better if he could separate emotion from fighting tactic and it might have been friendly towards humans if they left him and his fellows alone.

Abilities & Skills

It is able to quickly dodge energy blast shot at it, it also seems to be relying on its size and stature to intimidate people and instill fear into them. Unlike the other Tanaka's it doesn't have a Tanaka Shell since most likely it is to big for one. Instead it breathes with a special breathing apparatus. It is very quick and durable being able to survive a building collapsing on top of it and quickly attacking the hunters and grabbing Kurono. It also can fly high into the air within mere seconds. It most likely is intelligent enough to understand and repeat some Japanese while also been able to think of a new way to kill Kurono after his first two attempts fail. It might also be able to influence his surroundings without touching, as the door it was sitting behind opened without anybody touching it.

  • (As it gang up on Kurono alongside the other Tanaka' before Kurono falls through the floor) "Groaaaaa!!"
