History Anime / BtX

* AlternativeForeignThemeSong: The airing in Taiwan had a particularly rare situation done by the Japanese companies themselves. Stabilized since [[TheEighties the late 80's]], Taiwan [[TheSongRemainsTheSame would leave all licensed anime opening and ending themes untouched, even when dubbed.]] But in ''B't X's'' case, Fence of Defense's opening theme, ''Haruka~SAILING FOR MY DREAM'' was replaced by [[Music/TMRevolution T.M.Revolution's]] ''HIGH PRESSURE'' midway through it's airing without prior notice despite WordOfGod personally handpicked [=FoD=]'s song and the song [[SleeperHit was selling tremendously well]] in Japan thanks to the anime; this was speculated as to 1) ''B't X'' [[GermansLoveDavidHasselhoff was popular]] and Sony Music wanted a piece of their pie, and 2) Sony Music wanted to officially package T.M.R to the the international anime fan base, redirecting the demographic into buying T.M.R's ''Triple Joker'' album since T.M.R was officially licensed in Taiwan and was doing well with his ''restoration Level 3'' album thanks to ''Manga/RurouniKenshin''. This made ''B't X'' as the second anime project in T.M.R's history with his name in it, albeit forcefully. ''Haruka~SAILING FOR MY DREAM'' was later placed back to it's normal state by the time of ''B't X's'' [[UsefulNotes/CompactDisc [=VCD=]]] release. Since the Japanese fanbase became aware of this over the years, they treated T.M.R's ''HIGH PRESSURE'' as a "[[BonusMaterial bonus]] theme song" to this series.

* DubNameChange: Teppei is named Marlon, Foh is changed to Falcon, Hokuto to Homer, Karen is named Lourdes and so ford. The only ones that remain somewhat the same are Kaos and Metal Face.

* PhlebotinumRebel: Any B't whose owners decides to confront the agenda of their Empire, in this case, The Four Spirit Generals. B'ts are programmed with UndyingLoyalty towards their owners, so if an owner makes an agenda, their B'ts will side with them. However, our titular B't X bares the special case in that he gets to make his own decision as to whether he should aid Teppei in saving his brother who is abducted by their Empire, or reunite with his original owner, who was put on exile. Either way, X is already on the "rebel" side in terms of the greater agenda, therefore he has to make the decision as to whether he should defy ''his loyalty program'' in favoring a new owner over his predecessor. [[PowerOfTrust In the end, he chose to work with his new owner]].

** PowerGlows: Comes with ThePowerOfTheSun package, whether with or without his armor, he will glow once he triggered the power button.

** LawOfChromaticSuperiority: Regardless of military rank, the color and technical specifications for all Machine Empire Battle Gears, including The Four Spirit Generals, are the same and in the color white. The armor Teppei initially received from X was also white; But after X's MidSeasonUpgrade, Hokuto deliberately tweaked X's system to surpass the TheEmpire's standards, including the Battle Gear System, which gives Teppei's new armor a cream-yellow hue.

* [[HyperspaceMallet Hyperspace]] PoweredArmor: The Battle Gears, a type of light-weight, flexible, yet extremely durable armor made from non-metal material. The Battle Gear system was focused on Teppei as his TransformationSequence, but anyone who owns a B't will have the Battle Gear System installed within their B't to be triggered once the command: "''[[ByThePowerOfGrayskull Battle Gear, ON!]]''" is spoken by their Donors in order for the B'ts to apply the armors onto their Donors from thin air. The Four Spirit Generals all have wore them in the manga, but only Teppei and Karen wears them in the anime.
