As his father Takeshi was first runner-up at the second Gunpla Battle World Championships, Sei is very talented at building Gunpla kits, but his piloting skills are very weak due to a subconscious desire to avoid damaging his Gunpla. Because of this, he has Reiji pilot his Gunpla while he provides navigational and tactical data during battle. He is shown to have feelings for his classmate, China Kousaka. The teamwork between Sei and Reiji gives them a competitive edge that earns them the Japan 3rd Block Championship and a shot at the 7th Gunpla Battle World Championships. The duo fight their way to the final round of the tournament, where they defeat their longtime rival Tatsuya Yuuki (a.k.a. Meijin Kawaguchi the 3rd) and become World Champions. In the very last part of the series is shown that he actually is quite skillful as a Fighter when he almost defeats Tastuya Yuuki when the battle for fun with their machines crudely repaired before the last Plavsky Particles disappear. Sei finally gains confidence in being a Gunpla Fighter himself as the defending champion one year later, to keep his promise to Reiji in becoming stronger so, when Reiji finally comes back they can battle each other in earnest.

During his spare time, Mr. Ral mentors Sei, Reiji, and China, and hangs out with veteran Gunpla Fighters at a bar. Nicknamed the "Blue Giant" (青い巨星), Mr. Ral appears to be very well known and respected amongst even the best of the Gunpla Building and Battling communities, though the reason as to how he gained this recognition has yet to be fully explained, it is not until the last chapter when he shows a glimpse of his true power when he and Master Chinan rushes in middle of the last fight and wipe out hundreds of enemy machines in matter of seconds, leaving the main cast astonished of how ridiculously strong they are. The only ones in-universe who do not appear to know his background are the main cast, though they still view him as a very close friend.

 * Tatsuya Yuuki is the president of the student council and captain of the model-building club. Having won the Japan 3rd Block Championship in the previous year, he is the school's top Gunpla Fighter and Sei and Reiji's rival. His piloting skills earned him the nickname "Crimson Comet" (紅の彗星). In the middle of the current Gunpla Battle Japan 3rd Block Qualifying Tournament, Tatsuya is forced to bow out of competition and take an indefinite leave from school due to a personal emergency, which centers around his involvement with Plavsky Particle System Engineering (PPSE). However, he once again faces Sei and Reiji in an unsanctioned Gunpla Battle that ends with both Gunpla destroyed. Following this battle, Tatsuya resurfaces at the 7th Gunpla Battle World Championships as the PPSE Works Fighter Meijin Kawaguchi the 3rd (三代目メイジン・カワグチ), wearing sunglasses as a nod to Quattro Bajeena of Mobile Suit Zeta Gundam. As the current Meijin, Tatsuya vows to bring back the fun and enjoyment of Gunpla building, which was disregarded by his predecessor's philosophy of absolute victory. He fights his way toward the final round of the tournament, but interference and mental manipulation by Chairman Mashita hinders his chances of winning the championship, as he loses to Sei and Reiji, freeing him of his mental control, regretting that Chairman spoiled what both sides wanted to be a fun and earnest battle, leaving the result as irrelevant. Following the destruction of the giant Arista that is used to create Plavsky particles, Tatsuya battles Sei and Reiji for one last time with their crudely repaired Gunpla before the particles in the arena disappear. He gives up his moniker as Meijin and settles down as a consultant for Gunpla builders. In Gundam Build Fighters Try set seven years later is shown that he still retains the title as Meijin Kawaguchi III and have won several times the World Championship in the meantime.

Nicknamed the "Italian Dandy" (イタリアの伊達男), Fellini is a playboy, and sometimes attempts to court women by offering them a Gunpla; a fault that lands him in hot water on occasion, especially at the World Tournament where the ex-boyfriends of many of the women he courted band together to take revenge against Ricardo for stealing their girlfriends. Despite his playboy easygoing attitude when it comes in terms of Gunpla Battles he is deadly serious as shown in his Tournament Qualification Match against Reiji and Sei, as he was already qualified and the boys needed to get points. He could have lost on purpose to spare his Gunpla of damage, instead his pride as Fighter drove both sides to a head-to-head match that nearly completely destroyed both machines ending the battle in a draw. Fellini makes it through the finals, but is defeated by Aila Jyrkiainen in the quarterfinals after Kirara convinces him to concede instead to selfdestructing his Fenice in an attempt to take his opponent with him as he wasn't set to lose a match. Is shown that, despite his playboy status he has reciprocated feelings for Kirara. He returns at the Gunpla Eve festival with the Wing Fenice rebuilt as the Gundam Fenice Rinascita.

 * Aila Jyrkiainen is a Gunpla Fighter from Finland who was originally from the Flana Institute. Once a homeless orphan, she was recruited by Nine Barthes of the Flana Institute due to her ability to accurately predict the outcome of a Gunpla Battle by observing the movement of the Plavsky particles. Several years after her training, Aila joins "Team Nemesis" (チーム「ネメシス」), a Gunpla Battle team that is bent on conquering the 7th Gunpla Battle World Championships. Aila becomes the reigning Finnish Gunpla Battle champion after defeating Carlos Kaiser in mere seconds. At the start of the championship tournament, she begins a rivalry with Reiji after they fight over the last meat bun at the nearby mall. Like Reiji, she has a hearty appetite. Despite slowly becoming friends with Reiji, she does not reveal her identity to him or Sei due to the special Embody suit she wears during Gunpla Battle. Due to her developing relationship with Reiji, Aila begins to doubt her abilities as a Gunpla Fighter, which forces Barthes to override her Embody suit, causing her to go berserk during her battle with Fellini. Their relationship is strained when Reiji discovers her identity under the helmet. Before the semifinal battle between the Star Build Strike Gundam and Qubeley Papillon, China gives Aila a pendant with Sei's Arista as a good luck charm. In the heat of the battle, the Aristas worn by Reiji and Aila combined with the Plavsky particles trigger a telepathic communication between them, with Reiji convincing Aila to remove her helmet and be herself. Eventually, despite rejecting the Embody system and using her own abilities, Aila loses to Reiji, but finally discovers the fun in the sport. Upon her release from Team Nemesis, she is offered a place to stay by Rinko, based on a deal given to her by Reiji. Toward the end of the series, Aila makes a wish and has herself teleported to Arian to live with Reiji. In Gundam Build Fighters Try Island Wars, it is revealed that she had a daughter with him.

Iori Hobby Shop

 * GAT-X105B/FP Build Strike Gundam Full Package (ビルドストライクガンダム フルパッケージ)
 * The Build Strike Gundam is Sei Iori and Reiji's first Gunpla based on the GAT-X105 Strike Gundam from Mobile Suit Gundam SEED. It is equipped with four head-mounter vulcan guns and two beam sabers; other armament consists of a Chobham shield and a Beam Gun that can be upgraded into a Beam Rifle or an Enhanced Beam Rifle. When docked with the Build Booster (ビルドブースター), it becomes the "Full Package", which features an increase in performance and the addition of two Variable Speed Beam Rifles. The Build Booster also detaches to continue the battle when the Gundam sustains critical damage. The Build Strike Gundam Full Package is destroyed in its battle with the Zaku Amazing.
 * GAT-X105B/ST Star Build Strike Gundam (スタービルドストライクガンダム)
 * The Star Build Strike Gundam is an improved version of Sei and Reiji's first Gunpla, constructed around the inner frame of the 1/144 scale Real Grade Aile Strike Gundam kit and reinforced to withstand more abuse during battle. It is equipped with a new booster system called the UB-01 Universe Booster (ユニバースブースター). The Star Build Strike Gundam has three new features that differentiate it from other Gunpla. The first feature is the Absorb System, in which it uses the Absorb Shield (アブソーブシールド) to consume beam-based attacks and store them as Plavsky particles. The second feature is the Discharge System, which uses the stored Plavsky particles and converts them into three special attacks: Speed, Rifle, and Aqua. Discharge Speed Mode forms "Plavsky Wings" (プラフスキーウイング) that increase maneuverability and enable the Gunpla to execute an attack similar to the Turn A Gundam's "Moonlight Butterfly". Discharge Rifle Mode directs all power to the Enhanced Beam Rifle and uses the Plavsky Gate to amplify the attack into a shower of beam blasts or one giant blast. The third and final feature is the Radial General Purpose (RG) System, which reroutes all energy to the limbs or entire body for quicker response and concentrated attacks such as the Build Knuckle (ビルドナックル). For its final battle with the Gundam Amazing Exia Repair, the Star Build Strike is fitted with the Gundam Fenice Rinascita's arms and the Crossbone Gundam Maoh's Crossbone Gun & Swords.
 * GAT-X105B/CM Build Strike Gundam Cosmos (ビルドストライクガンダムコスモス)
 * The Build Strike Gundam Cosmos is an improved version of the Star Build Strike Gundam, used by Sei as defending champion in the Japan 3rd Block tournament of the 8th Gunpla Battle World Championships. In Gundam Build Fighters: GM's Counterattack, the Build Strike Cosmos is stolen by the Gunpla Mafia and commandeered by Mikio Mashita to challenge Sei's new Star Burning Gundam. Sei manages to recover the Build Strike Cosmos before Mikio transfers his control system to the Psycho GM.


 * RX-178B Build Gundam Mk-II (ビルドガンダムMk-II)
 * The Build Gundam Mk-II is Sei and Reiji's second Gunpla based on the RX-178 Gundam Mk-II from Mobile Suit Zeta Gundam as a substitute for the Build Strike Gundam Full Package in the Japan 3rd Block Qualifying Tournament. Like the Build Strike Gundam, the Build Gundam Mk-II is docked with the Build Booster Mk-II (ビルドブースターMk-II), arming it with two forearm mounted Beam Rifle Mk-II units (based on the ORX-005 Gaplant's main weapons). Following the completion of the Star Build Strike Gundam, the Build Gundam Mk-II is kept as a backup unit or for sparring matches with other Gunpla such as the Beargguy III. In the last episode it is shown that the Build Booster can dock with the Star Build Strike.


 * SB-011 Star Burning Gundam (スターバーニングガンダム)
 * The Star Burning Gundam is Sei's Gunpla in GM's Counterattack. It is the predecessor of the Build Burning Gundam used by Sekai Kamiki in Gundam Build Fighters Try. Like the Build Strike Gundam, the Star Burning Gundam is powered by the RG System. When the Build Strike Cosmos is stolen by the Gunpla Mafia, Sei uses the Star Burning Gundam to battle them, eventually squaring off against the Build Strike Cosmos before finishing off the Psycho GM with the "Hyper Star Burning Knuckle" (ハイパースターバーニングナックル).


 * PF-78-1 Perfect Gundam (パーフェクトガンダム)
 * The Perfect Gundam is Takeshi Iori's second Gunpla, based on the custom mobile suit from the manga Plamo Kyoshiro and the Mobile Suit Variation Gunpla line. It is essentially an RX-78-2 Gundam fitted with the Full-Armor System and Weapon System (FSWS) to increase its offensive and defensive capabilities. Because such an upgrade uses up more power, a propellant tank is fitted over the existing backpack.


 * MS-07B Gouf (グフ)
 * The Gouf is Mr. Ral's Gunpla based on the Zeon mobile suit from Mobile Suit Gundam. In episode 3, Mr. Ral uses a "Best Mecha Collection" (ベストメカコレクション) version of the Gouf while sparring with Reiji and the Build Strike Gundam; due to the old-style construction and limited articulation, as well as Mr. Ral's momentary inattentiveness, the Gouf is easily defeated in the fight. In episode 5, Mr. Ral shows off his expertly detailed High Grade (HG) Gouf at Iori Hobby Shop; however, instead of using it for Gunpla Battle, he displays it to remind Reiji of the hobbyist aspect of Gunpla.
 * MS-07R-35 Gouf R35 (グフR35)
 * The Gouf R35 is a modified version of Mr. Ral's Gouf. It is equipped with two shields mounting a pair of fixed Gouf hand machine guns on the undersides, two heat swords stored in its redesigned legs, and additional vernier thrusters on its skirt armor and legs. In episode 3 of Gundam Build Fighters Try it is revealed that "R35" stands for "Ral, 35 years old."

Seiho Academy

 * MS-06R-AB Zaku Amazing (ザクアメイジング)
 * The Zaku Amazing is Tatsuya Yuuki's first Gunpla based on the MS-06R-1A Zaku II High Mobility from the MSV (Mobile Suit Variation) sub-line, repainted in Char Aznable's pink and maroon colors. It is fitted with reactive armor plates taken from a tank model and equipped with a long rifle, two handguns, two Heat Nata knives, and two shoulder mounted rocket launchers. In the event of critical damage during battle, the Zaku Amazing's armor plates eject to form the Amazing Booster (アメイジングブースター). The Zaku Amazing is destroyed in its battle with the Build Strike Gundam Full Package.


 * KUMA-03 Beargguy III (San) (ベアッガイIII(さん))
 * The Beargguy III, also referred to as "Mr. Beargguy III", is China Kousaka's Gunpla based on the GPB-04B Beargguy from Model Suit Gunpla Builders Beginning G (itself being based on the MSN-04 Acguy from Mobile Suit Gundam), repainted in yellow with its head reshaped to resemble more of a teddy bear than the original. China envisioned Beargguy III to be a teddy bear who changed into a robot; hence the amount of cotton underneath the armor. Beargguy III is capable of shooting cotton from its mouth to entangle opponents. It is also armed with beam sabers mounted inside its mouth and arms. The ribbon on the Gunpla's back can be removed to reveal a hardpoint to mount special weapons. Seven year later, it appears that China's one-of-a-kind Beargguy III had gained enough exposure and become such an immensely popular design that it had been licensed and officially released by Bandai as a regular Gunpla kit (possibly in multiple colors), and is seen as a fairly popular Gunpla among girls and small children. It even appears to have become something of a mascot, as some of the staff working at "G-Muse" (Heavily implied to be Gundam Front Tokyo, a part of the Diver City shopping center in Odaiba) even wear Beargguy III costumes around customers.

PPSE

 * PPMS-18E Kämpfer Amazing (ケンプファーアメイジング)
 * The Kämpfer Amazing is PPSE Works' Gunpla based on the MS-18E Kämpfer from Mobile Suit Gundam 0080: War in the Pocket and is the corporation's entry to the 7th Gunpla Battle World Championships. It was developed and built by Allan Adams of PPSE Works and is piloted by Tatsuya Yuuki under the pseudonym Meijin Kawaguchi the 3rd. The Kämpfer Amazing is armed with two or four Weapon Binders that store and eject various weapons from pistols to long range sniper rifles. The Weapon Binders also act as rocket boosters and can combine into a large beam cannon.


 * MS-06F Zaku II Mass Production Unit (量産型ザクII)
 * The unmanned Zaku II used in the championship battle royal is a 1/48 scale Mega Size Model (メガサイズモデル), sent in by Chairman Mashita to target the Star Build Strike Gundam. Due to its difference in scale, this Zaku II towers over all of the competing Gunpla, which are at 1/144 scale. While equipped only with its standard armament, it can crush an enemy Gunpla with one hand. Ultimately, the Zaku II is destroyed by the Star Build Strike Gundam, with the help of the Wing Gundam Fenice and Gundam X Maoh as well as unexpected assistance from the Sengoku Astray Gundam and Kämpfer Amazing.


 * PPGN-001 Gundam Amazing Exia (ガンダムアメイジングエクシア)
 * The Gundam Amazing Exia is PPSE Works' second Gunpla based on the GN-001REII Gundam Exia Repair II from Mobile Suit Gundam 00 and developed under the code "A5". Following Meijin Kawaguchi the 3rd's battle with the Renato Brothers, Allan Adams orders the deployment of the Amazing Exia as the replacement of the Kämpfer Amazing, despite the Gunpla being 80% complete. Just like the original Gundam Exia, the Amazing Exia's special feature is the Trans-Am System that increases its capabilities threefold for a short period of time, at the expense of a significant drop of output once exhausted. Prior to the final round of the tournament, it is fitted with a Trans-Am Booster (トランザムブースター) that optimizes the Gunpla's performance in Trans-Am mode. Like the Star Build Strike Gundam, the Trans-Am Booster is a backpack that detaches from the Gunpla and transforms into a flight unit, using the GN Drive as its main fuselage. After it is heavily damaged following its defeat at the hands of the Star Build Strike Gundam in the final round of the tournament, it is repaired with several parts. Just like the GN-001RE Gundam Exia Repair from Mobile Suit Gundam 00 season 2, it sports a cloak over its left shoulder (though it retains its left arm); it also uses a stock Exia upper torso in place of its damaged unit. Further repairs are made for its final battle with the Star Build Strike Gundam using the Kämpfer Amazing's right arm, left leg armor plates, beam rifle, and beam saber.


 * PPGN-001 Gundam Exia Dark Matter (ガンダムエクシア ダークマター)
 * The Gundam Exia Dark Matter is an altered version of the Gundam Amazing Exia. Developed in cooperation with Nine Barthes of the Flana Institute, it incorporates the Embody System previously used in the Qubeley Papillon. Unlike the previous version, the Exia Dark Matter's Embody System uses Plavsky particles that enable Chairman Mashita to telepathically control Meijin Kawaguchi using his personal Arista. It is repainted in a red and black color scheme reminiscent of the GNY-001F Gundam Astraea Type F from the Mobile Suit Gundam 00F side-story manga, and is fitted with a winged backpack that gives it a resemblance to the ZGMF-X11A Regenerate Gundam from Mobile Suit Gundam SEED Astray R. Effectively, the Trans-Am booster becomes the Dark Matter Booster (ダークマターブースター).


 * MSM-07-A Amazing Z'Gok (アメイジングズゴック)
 * The Amazing Z'Gok is Meijin Kawaguchi's Gunpla in GM's Counterattack, based on the MSM-07S Z'Gok from Mobile Suit Gundam. Its arms have been modified with new forearms that can transform into different weapons to give it the abilities of other Zeon marine mobile suits.


 * Mock (モック)
 * The Mock is a series of unmanned mass-production Gunpla launched when the giant Arista forms a scale replica of the Zeon fortress A Baoa Qu over the PPSE Stadium. Their individual abilities and AI appear to be unimpressive, but their enormous numbers still make them a major obstacle. The Mock gets its name from being a "knockoff", or a bootleg of official Gunpla.

Gunpla Fighters (Japan)

Repainted back into its original purple and gray colors, it is equipped with the Valuable Pod (ヴァリュアブルポッド), a booster unit that holds two Gatling guns, two missile shields, and heavier shoulder armor that stores two beam swords. Though Sazaki defeats Monda's Turn X with its increased firepower, the Gyan Vulcan is defeated almost immediately afterward by Ricardo's new Gundam Fenice Rinascita.


 * Knight Gundam (騎士(ナイト)ガンダム)

 * The Master Gundam is Master Chinan's secondary Gunpla, which is also based on Master Asia's Gundam unit from Mobile Fighter G Gundam. Unlike Master Chinan's Kowloon Gundam, this Master Gundam sports less modifications, which consist mainly of gold-colored armor plates.

Gunpla Fighters (International)

 * XXXG-01WF Wing Gundam Fenice (ウイングガンダムフェ二ーチェ)
 * The Wing Gundam Fenice is Ricardo Fellini's Gunpla based on the XXXG-01 Wing Gundam from Mobile Suit Gundam Wing. A Gunpla that Fellini has owned since childhood, it uses a unique asymmetrical design, moving both wings to the left side and breaking off the right side of the V-fin antenna, as well as using different shoulder and leg armor plates on each side. It also has heterochromia, wherein its left eye is green and its right eye is pink. The Wing Gundam Fenice is armed with a Beam Rapier, a Buster Rifle Custom, a Shoulder Beam Cannon and a Beam Mantle, a cape-like beam shield that gives it a matador profile. It is also equipped with a self-destruct mechanism. The Wing Gundam Fenice is also named after the Italian opera house La Fenice (which in turn Fenice is the italian word of Phoenix). During battle, it can dock with a unicycle-like support vehicle called the Meteor Hopper (メテオホッパー).

It incorporates a Samurai motif similar to the Musha Gundam line, armed with two Samurai Swords (サムライソード) and an Oni Shield (鬼の盾). The shoulder armor transforms into an extra pair of arms. The Samurai Swords have a special coating that changes the Plavsky particle band and allows them to slice through enemy beam attacks; if the coating matches the Battlefield's control particle band, the blades can cut through any defensive barrier such as a GN Field. The Sengoku Astray's final attack is the Particle Fa jin (粒子発勁), which allows it to transfer Plavsky particles into the enemy Gunpla and destroy it from within.


 * 忍ノ参 Ninpulse Gundam (忍パルスガンダム)

 * The Qubeley Papillon is Team Nemesis' Gunpla based on the AMX-004 Qubeley from Mobile Suit Zeta Gundam and Mobile Suit Gundam ZZ, piloted by Aila Jyrkianen. Its main weapon is the Lancer Bit, a giant lance shaped like the Qubeley's funnel. The Qubeley Papillon is also armed with funnels molded in clear plastic, which make them invisible in battle. The Gunpla's control system is equipped with the Embody System, which takes control of Aila's mind and enhances her ability to visualize the Plavsky particles, making her an unstoppable fighter with detrimental results to her consciousness.


 * AC-01 Miss Sazabi (ミスサザビー)
 * The Miss Sazabi is Aila's Gunpla based on the MSN-04 Sazabi from Mobile Suit Gundam: Char's Counterattack and her first one following her separation from Team Nemesis.

 * RGMGM-79 GM/GM
 * The GM/GM is E's custom Gunpla in GM's Counterattack, based on the RGM-79 GM from Mobile Suit Gundam. There are three different head variants for this unit: the standard GM, the RGM-79N GM Custom (from Mobile Suit Gundam 0083), and the FX-9900-D G-Bit D.O.M.E. (from After War Gundam X).

 * Musha Gundam Mk-III (武者頑駄無真悪参)
 * The Musha Gundam Mk-III is Nenene's custom SD Gunpla. While not a match for Mao's Gundam X Jumaoh, it benefits from Nenene's tactic of distracting Mao with her Shrike Team bikini. The Musha Gundam Mk-III is ultimately destroyed by the Gundam X Jumaoh's X Cannon.
