The Three Civilizations are characters from the anime and manga of Bobobo-bo Bo-bobo.
The Three Civilization ninjas the final three of the assassin Ninshū. They fight together as a strange ninja team (possibly as a parody to fellow Jump manga Naruto) who, coincidentally, are named after three of the first four great ancient civilizations of the world (but not Egypt, oddly enough). Their battlefield is a giant toilet. They originally resided at OVER's Castle, until Bo-bobo arrived to destroy it.
Mesopotamia Civilization (メソポタミア文明, Mesopotamia Bunmei), also known as Mesopotamian Guy, is a tentacled-horned nose creature, is the trap-master of the castle, controlling an entire room of nearly inescapable traps as well as consistently trying (and failing) to set them off during the battle with Bo-bobo's team. He also appears to try and use a "cloning jutsu". that is sort of obvious to its opponents (since the "clones" are just hot dogs cut into the shape of octopi).
Indus Civilization (インダス文明, Indasu Bunmei), also known as Indus Guy in the English anime, is a firecracker dressed in ancient Japanese garb, is the quiet one (compared to his partners) who fights with a sword like a samurai and can open up his body to reveal something unexpected to assist him.
Kouga Civilization (黄河文明, Kōga Bunmei), also known as The Yellow River in the English Anime, is the human leader of the trio. This one fights with a sword as well, but has various ninjitsu abilities such as a freezing sweat ability and... curling? (it should be noted that the symbol on his outfit bears a close resemblance to the Tidus/Jecht symbol featured throughout the game Final Fantasy X). Interestingly in one episode he removes his top to reveal a female body underneath (although this could just be the majide metamorphosis).
Working for OVER
The fight between the Hajikelist trio (Bo-bobo, Don Patch and Tokoro Tennosuke) and the trio of assassins, takes place upon... a giant toilet. The fight begins randomly, until Heppokomaru and Tennosuke fall into the toilet. The water makes their bodies expand, and if left in too long, they will explode! The Three Civilizations's traps don't work out so well, but they make up for it by being extra sneaky! Bo-bobo tries his hardest to defeat the evil Civilizations, but even more becomes at stake, when Dengakuman and Don Patch fall into the toilet as well! Alone and outnumbered it would seem that Bo-bobo is outmatched, until Bo-bobo comes up with an idea to even the odds; he gets Tennosuke out by reading pages of his personal diary aloud, and gets Don Patch out by putting Ya-kun on a fishing pole.
With the fight now 3-on-3, the Civilzations try out some of their own personal techniques, but nothing, from Kouga's freezing sweat technique to Mesopotamian's clone ability, works out in their favor. The fight seems to turn around when they challenge the rebels to a small game of hockey, but it winds up closing the toilet seat on top of their heads! With their arms and legs stuck, it seems that no one can attack anyone... until Bo-bobo starts breathing fire! When the toilet seat finally comes up, the rebels use their most vicious attack yet; a fusion which leads to the warrior Bobopatchnosuke! The Civilizations still don't think much of the fusion and try to attack him, only to be branded by his swords face! Then, Bobopatchnosuke infects them all with Majide, and transports them into "Majide Time". Here, the ninja trio are told not to say "are you serious" (majide) or else random things will happen! However, the ninja's eventually say the forbidden words, and all sorts of crazy thing happen, including Mesopotamian being revealed to be a human, Kouga being revealed to be a woman, Kouga marrying Indus, and the world being blown up by Bobopatchnosuke! Finally, the fusion decides to finish this, by smacking them with his "Fist of the Eyelash"!
The New Emperor Playoffs
The Civilizations are not sen again until the New Maruhage Emporer Playoffs. Here, they meet Bo-bobo and Heppokomaru again in one of the lower levels of the contest, where they are forced to work together to defeat Ramen master Menma. Up to this point, they have been beaten by Menma once already, and have been hiding in a card board box in shame. When Bo-bobo shows up, they regain their resolve to beat him, and decide to defeat both him and Menma in her Ramen-Eating Contest. Their goal is to make a bowl of ramen, feed it to their opponents and get them to say that it is delicious, but they can't even get that right, as Mesopotamian makes a bowl of green sludge, and Kouga tries to pass off an Egyptian mask as ramen, and Indus guy just puts himself into a bowl! Then, their "meals" are put onto a revolving table, and they all stop in front of Mesopotamian, who must eat them all! Throughout the fight, the Civilizations are mercilessly battered by Bo-bobo. They finally put a stop to Menma, when Indus guy (who is now a dumpling) stops in front of her. Since she doesn't eat him, she herself is disqualified from her own challenge! Bo-bobo then rewards them for helping him,... by smacking them one last time with his "Fist of Nosehair"! At the end of the Reverse Maruhage Empire saga, the Civilizations wind up managing a small restaurant.
Though they truley have no roll in Shinsetsu, the Civilizations appear once again in the sequel series. Because of Tsuru Tsurulina III's orders to have everyone from the fourth era punished for their failures, the three are seen being tortured! Their torture it being tickled by metallic gloves! After the fall of the Neo Empire, the three can be spotted in the last chapter sitting near a river.
