Written by Masami Kurumada after he finished Saint Seiya prematurely due to the insistence of his publishers four years ago, B't X has a similar premise but with a different setting and execution. Some people consider it Saint SeiyaWITH SCIENCE!!!The story begins with Teppei Takamiya, as he travels to China after years of living quietly in the fictional Kamui Island. He attempts to reunite with his brother Kotaro, who left Germany five years ago to study robotics at a university. Unfortunately, no sooner than his brother begins an exhibition about an advanced form of machine, he's kidnapped by a Humongous Mecha in the shape of a wasp and a servant of the Machine Empire. Teppei starts a chase, using a gauntlet known as the "Messiah Fist" to hold onto the wasp as it travels to a secretive base in the Gobi Desert which serves as the Empire's headquarters.Getting thrown into a garbage heap and facing a cyborg he somehow is familiar with, Teppei's blood awakens a relic from the past; a kirin-type B't known only as "X" which, five years ago, was considered the most powerful B't in existence. Both are equally stubborn, although quite different in many ways, and after a few initial squabbles, X resolves to help Teppei in his quest to save his brother.Along the way, we find out quite a bit about Teppei's past, the reasons Kotaro was kidnapped, and the Machine Empire's plans involving a home-grown monster of Devil Gundam proportions.Both the manga and the anime have been licensed in America.As of June 2013, they have revived into a PACHINKOGAME!!
This series provides examples of:
Action Girl: Teppei's teacher Karen, who had been one of the Empire's Four Knights up until five years ago. Aramis is another example.
The Atoner: Foh, who almost let his best friend kill him over the whole dead little sister thing.
Batman Can Breathe in Space: Applies to everyone with a B't. Except for instances involving the B'ts' Weaksauce Weakness (see below), a B't's protective "Guard System" enables it and its rider to withstand anything ranging from magma to the void of space.
Cybernetics Eat Your Soul: Made apparent with the cyborg named Metalface, who considers sacrificing his own flesh and blood for an immortal robotic body to be an obvious choice.
Dark Is Evil: The Death God and his Bat BT are a very straight example
Dark Is Not Evil: Karen creates a black version of X, Shadow X, that is just as powerful, a girl, and good.
Deadpan Snarker: At least in the Tokyopop manga, the narrator pulls this off in the recap of the previous volume, complete with Lampshade Hanging various issues such as Teppei's Vitriolic Best Buds status he eventually gets with Foh and company, the fact that Juggler's real face looks just like a clown face anyways, etc.
Defeat Means Friendship: Averted. Teppei never actually defeats Foh in a fight and the best he does against Ron is fight him to a draw. he also never duels either Karen or Hokuto. However, they all eventually side with him.
Expy: Pretty much everything in this series can be tracked down to Saint Seiya:
Teppei looks very much like an older Seiya.
Ron looks a lot like Shiryu. This, however, doesn't apply to his personality.
Foh also looks a lot like Hyoga. Then again, it doesn't apply to his personality as well. He can also be seen as the unholy child of Saga and Shaka, with a dash of Lyra Orpheus thrown in. With Shion's hair.
Adding to the "Huh" factor of the look-alikes, Kotaro looks an awful lot like Shun, if he grew up and cut his hair real short.
Hokuto is pretty much like Mu with Shaka's aloof personality.
Karen is basically Aioros, since both are labeled as traitors despite having the best intentions and have a great deal of an impact on the main characters.
And last, but not least, the B'ts and Battle Gears. Subverted in that they don't split-up to form an armor for their owner.
The Faceless: We do not see the Machine Emperor in person until the final volume, and never once in the anime.
Filler: three episodes dealing with the Dark Knights (while in the manga they were defeated all together and very anticlimactically), along with encountering an old member of the Four Knights and also a reclusive scientist.
Filler Villain: Chaos and the three Dark Knights. Chaos plays an important role, however, coining the phrase "Buddy", which is used a lot in the remainder of the series, and furthering Teppei's Character Development. The Dark Knights serve to foreshadow Teppei's connection with the Sun, and the potential he has.
Heel-Face Turn: Plenty, especially when people realize how dangerous Raphaello really is.
Heroic Sacrifice: Again, lots of people. Metalface managed to pull it off twice. Once sacrificing a means of safely travelling a minefield to help out a young Karen years ago which caused him to require his cyborg parts, and once again to secure the force that would destroy Raphaello at the cost of his body
High Heel-Face Turn: A noticeable aspect in this series. Pretty much every female character who serves in the Machine Empire, such as Salome, Karen, and Nasha, will end up having the brains to help Teppei by the end. Too bad that all of them die in at least one version of the story with the sole exception of Karin. In addition, of all the Devil Knights, the sole female Salome is the only one to decide to help Teppei once she regains her faith in humanity. Unfortunately, Juggler had different ideas.
Idiot Hero: He grows out of it eventually, but Teppei's VERY MUCH this trope for a good chunk of the series. It takes a double whammy of him almost getting X killed and Fou telling him how much of a fucking loser he is for him to wise up.
Incurable Cough of Death: Hokuto suffers from radiation poisoning. During at least one point in the series, it catches up to him at the worst possible moment.
Kick the Dog: Misha violently blows up a mooks helmet because he was a bit too insistently asking for orders.
Kill 'em All: the manga kills off a lot of people, and in the end pretty much the only two protagonists, both human and B't, that survive are Teppei and Kotaro. In the anime, the last scenes implies that everybody died, including Teppei and Kotaro.
Mid-Season Upgrade: After X dies for the first time, Hokuto repairs him. Among other things, Teppei's armor changes and he gets a new attack.
Mighty Glacier: Hokuto's B't Max is infamous among the Empire for having unparalleled defense. This doesn't stop Dr. Poe from destroying all of her except for her head. In terms of actual people, Amigo fits this.
Mook-Face Turn: Karin, Karen's younger sister who calls it quits fairly early and spends the rest of the series taking care of the kids at Foh's orphanage.
Musical Assassin: Foh uses a violin bow as a weapon to go along with Je T'aime's attacks.
Must Make Amends: Marcellos does a lot of very, very stupid and amoral things, striving him to do everything he can to help Kotaro when that time comes. In the anime, his knowledge of the tower's layout is utterly crucial.
Nuclear Weapons Taboo: Averted. Hokuto's radiation sickness was triggered by being just outside the direct killzone of a nuke that destroyed his home and family and he's got the burns on his back to prove it. Aramis also tries to kill Raphaello by loading Rosemary up with every nuclear warhead she can find and performing a Heroic Sacrifice, but Raphaello's power makes it a Senseless Sacrifice.
The Power of Love: The only reason Foh was able to defeat the Demon Knight Gai. with his bowstring broken and Je T'aime's speakers destroyed, he used his bows and she used her wings to resonate at the frequency of a baby crying out for a mother's love and defeated him.
Weaksauce Weakness: B'ts are vulnerable to certain sound frequencies that damage fragile parts of their systems.
What Measure Is a Non-Human?: Teppei initially views X as a tool to help him rescue Kotaro. It takes a while for him to realize X has his own thoughts and feelings. This also applies to Metalface, although his realization came too late.
You Shall Not Pass: In the anime, when at death's door, Amigo wraps his arms around metal pipes and blocks a door with his body, which stalls the enemy mooks long enough for Teppei to arrive and finish them off.
