## Main characters
### Houtaro Ichinose

Houtaro Ichinose (一ノ瀬 宝太郎, Ichinose Hōtarō) is a second-year freshman at Furasu High School (富良州高校, Furasu Kōkō). He becomes a student at Alchemist Academy after he was entrusted by Fuga Kudo with the GotcharDriver (ガッチャードライバー, Gatchādoraibā) belt and the remaining Chemies during their brief encounter with each other, which ultimately led the former to rediscover his childhood past connections with the Chemies. Following the Dark Kings' return and Glion's resurrection, Houtaro's ideals in coexistence between humans and Chemies were challenged by his increasing rivalry with Supana and the public's distrust against them. Eventually, by the time Glion threatens to cover the entire planet in gold, Houtaro comes to the conclusion of creating a second planet Earth for the Chemies to inhabit and defeats him once and for all. Realizing that the general population has yet to accept the existence of Chemies, Houtaro and the entire Alchemist Academy decide to make recurring visits to the second Earth while working his way to achieve his dream of peaceful coexistence. After graduating high school, he studies to obtain a chef's license.
Utilizing the Hopper1 and Steamliner Ride Chemy Cards (ライドケミーカード, Raido Kemī Kādo) in conjunction with the GotcharDriver, Houtaro can transform into Kamen Rider Gotchard Steamhopper (スチームホッパー, Suchīmuhoppā).

While transformed, he is equipped with the back-mounted Fire Dokkan (ファイヤードッカーン, Faiyā Dokkān) booster, which grants superhuman speed and pyrokinesis.

#### Future Houtaro

Future Houtaro (未来の宝太郎, Mirai no Hōtarō) is the cynical counterpart of Houtaro Ichinose who briefly appeared in the series as his Rider form before his identity was revealed in the film Kamen Rider Gotchard: The Future Daybreak. After Glion successfully opened the Door of Darkness and lost his friends and right eye in the process, Houtaro fell into despair and his grief evolved his Ride Chemy Cards into Daybreak Chemy Cards (デイブレイクケミーカード, Deibureiku Kemī Kādo), with Gotchard himself becoming the color-inverted Kamen Rider Gotchard Daybreak (仮面ライダーガッチャードデイブレイク, Kamen Raidā Gatchādo Deibureiku). Following the acquisition of his own Gotcharigniter, the Future Houtaro went into the past and diverges his timeline into an alternate future by invoking his younger self's Fire Gotchard transformation at an earlier point. Once his mission ended, he returned to his timeline to continue his fight and rescue survivors of Glion's regime.
His actions in creating a diverged timeline however caught the interest of the alternate Glion into spreading his influence to the present day timeline and the Alchemys Union joining the Future Houtaro's fight. Having experienced his friends' deaths, the Future Houtaro try to dissuade them from joining him, but the encouragement from his present self and Rinne allows the Future Houtaro to regain hope and reestablish contact with his Chemies, in particular his timeline's Rinne. After defeating Kamen Rider Dorado and the Dark King, Gotchard Shining Daybreak travels through time to stop the monster from terrorizing the past, creating a bootstrap paradox wherein he is the Kamen Rider of Daybreak legend.
Similarly to his past self, the Future Houtaro utilizes the Daybreak Hopper1 and Daybreak Steamliner Daybreak Chemy Cards in conjunction with the GotcharDriver (Daybreak Ver.) (ガッチャードライバー (デイブレイクVer.), Gatchādoraibā (Deibureiku Vājon)) belt to transform into Kamen Rider Gotchard Daybreak Steamhopper. While transformed, he gains the use of Wild Mode to transform into a non-humanoid state based on his current form. He also wields the Gotcharge Gun and Gotchartornado. Additionally, he can combine the GotcharDriver (Daybreak Ver.) and Gotcharigniter to transform into the caped evolution of his Rider form; Kamen Rider Fire Gotchard Daybreak (仮面ライダーファイヤーガッチャードデイブレイク, Kamen Raidā Faiyā Gatchādo Deibureiku).
During the events of The Future Daybreak, the Future Houtaro gains the use of the Level Number EX Shining Hopper1 (シャイニングホッパー1, Shainingu Hoppā Wan) and Shining Steamliner (シャイニングスチームライナー, Shainingu Suchīmurainā) Ride Chemy Cards to transform into his ultimate form; Kamen Rider Gotchard Shining Daybreak (仮面ライダーガッチャードシャイニングデイブレイク, Kamen Raidā Gatchādo Shainingu Deibureiku).
Kamen Rider Gotchard Daybreak/Future Houtaro Ichinose is portrayed by Daigo. The flashback to his younger self is portrayed by Junsei Motojima, who also portrays the present-day Houtaro.

### Rinne Kudo

Rinne Kudo (九堂 りんね, Kudō Rin'ne) is Houtaro's classmate and a student at both Furasu High School and Alchemist Academy. During the events of the crossover film Kamen Rider the Winter Movie: Gotchard & Geats Strongest Chemy ★ Gotcha Great Operation, she reunites with her father Fuga in the dream world where he entrusts her with the AlchemisDriver (アルケミスドライバー, Arukemisudoraibā) belt and the High Alchemist Ring (ハイアルケミストリング, Hai Arukemisuto Ringu), granting her the ability to transform into Kamen Rider Majade (仮面ライダーマジェード, Kamen Raidā Majēdo). However, following her first transformation, Rinne loses access to her Rider powers until she saves Atropos from the Cerberus Malgam. After high school graduation, she studies abroad in the UK.
Utilizing the Unicon and The Sun Ride Chemy Cards in conjunction with the AlchemisDriver and High Alchemist Ring, Rinne can transform into Kamen Rider Majade Sununicorn (サンユニコーン, San'yunikōn). While transformed, she gains alchemy manipulation capabilities. She can also use other Gotchanko Chemy combinations from the Fantastic and Cosmic categories to assume a variety of forms, which are as follows:
* Mooncerberus (ムーンケルベロス, Mūnkeruberosu): An auxiliary form accessed from the Yoacerberus and Neminemoon Ride Chemy Cards.
Following Atropos' sacrifice, Rinne acquires the Majesty Driver (マジェスティードライバー, Majesutī Doraibā) belt and the Promise Alchemist Ring (プロミスアルケミストリング, Puromisu Arukemisuto Ringu), which she can use in conjunction with the Twilight Unicon and Twilight The Sun Ride Chemy Cards to transform into her ultimate form; Kamen Rider Twilight Majade (仮面ライダートワイライトマジェード, Kamen Raidā Towairaito Majēdo). While transformed, she gains photo- and umbrakinesis.
In the film Kamen Rider Gotchard: The Future Daybreak, Rinne's alternate self was one of the many casualties of Glion's regime, whereupon her death resulted with her spirit merging with Daybreak The Sun. However, as Houtaro became cynical and shutting his communication with his Chemies, Rinne's spirit was unable to reach him until their present selves encouraged him, allowing her spirit to reach the Future Houtaro and lending her support to Gotchard Daybreak.
Rinne Kudo is portrayed by Reiyo Matsumoto (松本 麗世, Matsumoto Reiyo). As a child, Rinne is portrayed by Liliana Ōno (大野 りりあな, Ōno Ririana).

### Supana Kurogane

Supana Kurogane (黒鋼 スパナ, Kurogane Supana) is an alchemist, a graduate of Alchemist Academy, and Houtaro's rival who initially viewed the Chemies as tools instead of living beings. His parents, Renchi (レンチ) and Suzu (スズ), were alchemists who were killed by Glion 10 years prior to the series. After accepting his past and managing to avoid becoming an unwitting pawn of Glion's schemes, Supana creates his own Alchemist Ring (アルケミストリング, Arukemisuto Ringu) to honor his parents' sacrifice, though he tends to fight his opponents alone. Realizing the horror of general population reacting to the Chemies' existence, Supana attempts to absorb them in a self-destructive charge against the Dark Kings, but was stopped by Houtaro before his plan can be carried out. Despite losing the ValvaraDriver and realizing how far he had fallen, his renewed resolve to fight alongside the Alchemist Academy allows Supana to restore his belt into the ValvaraDriver Kurogane.
Throughout the series, Supana has assumed the following forms:
* Valvarad (ヴァルバラド, Varubarado): Supana's Kamen Rider-esque warrior form accessed from the Madwheel Ride Chemy Card in conjunction with the wrench-like Valvarusher (ヴァルバラッシャー, Barubarasshā) sword/rifle hybrid.

** Kamen Rider Valvarad GT (仮面ライダーヴァルバラドGT, Kamen Raidā Varubarado Jī Tī): A special form accessed from the Daiohni GT and Gigantliner GT Ride Chemy Cards that equips Supana with a pair of self-propelling GT High Pressure (GTハイプレッシャー, GT Hai Puresshā) gauntlets.

During the events of the V-Cinema Kamen Rider Gotchard: Graduations, Supana loses access to this form as a result of the ValvaraDriver Kurogane's destruction by Ouroboros. However, Kyoka was able to rebuild it into the original ValvaraDriver and tune up its output to be on par with its upgraded self.

Alchemist Academy (錬金アカデミー, Renkin Akademī) is a secret school for young alchemists located in the basement of Furasu High School and run by the Alchemys Union (錬金連合, Renkin Rengō). Each student carries a Chemy Riser (ケミーライザー, Kemī Raizā) device, which is used in conjunction with Search Cards (サーチカード, Sāchi Kādo) to locate Chemies and Blank Cards (ブランクカード, Buranku Kādo) to capture them. Following Glion's defeat, with the union freed from his conspiracy, the academy is now under new management.

Despite being Houtaro's senior, the two became fast friends due to their shared interest for Chemies, especially UFO-X who inspired Sabimaru to create his own version of the Chemy Riser, nicknamed the "Sabi Riser" (サビーライザー, Sabī Raizā) by Renge, to summon it. During the rise of Level Number 10 Chemies, Sabimaru briefly becomes the first host of the DreaDriver against his will and had his knowledge of Chemies exploited against his own allies until Super Gotchard saved him from having his life force drained by the belt's power.

When Glion finally makes his move and reveals himself as the Three Dark Sisters' master in the present, Minato goes undercover by joining his side while becoming the fourth Kamen Rider Dread, in order to save his current students from neither suffering similar fates nor becoming another one of Glion's pawns behind the scenes. Once he finally overcomes his survivor guilt, Minato leaves Glion and returns to his students' side. He later marries Kyoka.
Minato is portrayed by Rikuto Kumaki (熊木 陸斗, Kumaki Rikuto).

### Three Dark Sisters

The Three Dark Sisters (冥黒の三姉妹, Meikoku no Sanshimai) are a trio of homunculus alchemists who work for Glion. In the film Kamen Rider Gotchard: The Future Daybreak, their alternate selves were dismissed by Glion after he created the Dark Death Masks as enforcers to his regime, forcing Atropos and Clotho to defect to the Future Houtaro's side at some point after Lachesis' death.

#### Atropos

Atropos (アトロポス, Atoroposu) is the oldest sister who resembles a child and is modeled after Rinne Kudo. She later becomes the fifth Kamen Rider Dread. Initially devoted to Glion due to the circumstances behind her creation, she was discarded by her creator after he achieved his goals, eventually sacrificing herself to protect Rinne from Gaelijah's attack. Despite her death, her spirit was able to intervene by assisting Twilight Majade and countering Gaelijah's prediction, resulting in the female Dark King's death.
Atropos is portrayed by Itono Okita (沖田 絃乃, Okita Itono).

#### Clotho

Clotho (クロトー, Kurotō) is the middle sister with enhanced physical strength. While devoted to Glion and the Dark Kings' cause, Clotho came into conflict with her personal interest after Lachesis defected to the Alchemist Academy and Atropos' slow downfall into insanity. Seeing her sisters died by the very superiors she served, Clotho goes into a suicidal charge against Kamen Rider Eld, but fails and dies by her creator's hands.
Clotho initially fights with Malgam forms through captured Chemies, with Glion's brief assistance allows her to transform into enhanced golden Malgam. She later becomes the third Kamen Rider Dread, initially sharing the DreaDriver with Lachesis until she gains full ownership after the latter's defection and Glion's brief demise. After being empowered by Gigist, she gains the ability to transform into the armored Clotho Rebis (クロトーレビス, Kurotō Rebisu), with Gaelijah eventually reverting her to normal when the transformation came at the cost of her sanity.
Clotho is portrayed by Kanon Miyahara (宮原 華音, Miyahara Kanon).

#### Lachesis

Lachesis (ラケシス, Rakeshisu) is the youngest sister who is the most agile, who is modeled after an aspiring singer. She later becomes the second Kamen Rider Dread, sharing with Clotho. Following her betrayal of Glion, Lachesis becomes an ally to the Alchemys Union and Kyoka's assistant. She wants to become Supana's lover once she is human, but is killed by Glion.
Similarly to Supana, Lachesis utilizes the Repli Madwheel Replichemy Card in conjunction with a Valvarusher to transform into the second Valvarad.
Lachesis is portrayed by Alisa Sakamaki (坂巻 有紗, Sakamaki Arisa).

### DreaDriver

The DreaDriver (ドレッドライバー, Doreddoraibā) is a malevolent sentient belt which was created by the Three Dark Sisters along with dark copies of the Ride Chemy Cards called Replichemy Cards (レプリケミーカード, Repurikemī Kādo) to counteract the likes of Gotchard and Valvarad (warrior) by either possessing its host or having one of the sisters utilize it to transform into Kamen Rider Dread (仮面ライダードレッド, Kamen Raidā Doreddo). However, normal humans who transform with this belt will have their life force drained.
Using Kenichi Saruhara's AI research, Glion modifies the DreaDriver to create the Dreatrooper (ドレットルーパー, Dorettorūpā), an autonomous version of Dread that allows it to operate without a host. When Glion converts the entire planet Earth into gold, Clotho uses the DreaDriver in a last ditch effort to take down her creator, only to lose her life in the process. Glion summons Dreatrooper Type Army as reinforcements to his campaign, but all of them are converted into raw materials by Gotchard into a copy of planet Earth for the Chemies to inhabit.
In the alternate timeline where he achieved world domination, Glion managed to produce Dreatroopers en-masse, with Type Army serving as grunts while being led by the normal Dreatroopers and the Dark Death Masks to fight Daybreak and the other survivors. Dreatrooper Type Army made their way to the present day timeline to expand Glion's rule, but they were destroyed by the combined efforts of the Alchemist Academy, Legend, Gavv, and a brief intervention from Tsukasa Kadoya.
A user of the DreaDriver utilizes the Repli Steamliner Replichemy Card in conjunction with the belt itself to transform into Kamen Rider Dread Type Zero (零式, Zeroshiki). While transformed, they can use other Replichemy Cards to grant themselves either an enhanced ability or the use of a Bloody (ブラッディー, Buraddī) weapon based on the corresponding card. Amidst its users, the DreaDriver acquires unique Replichemy Cards that can combine with Repli Steamliner to achieve stronger forms, which are as follows:
* Type One (壱式, Ichishiki): The silver-colored evolved form of Type Zero accessed from the Repli Steamliner and Unicon Replichemy Cards.
* Type Two (弐式, Nishiki): The crimson-colored evolved form of Type Zero accessed from the Repli Steamliner and Daiohni Replichemy Cards.
* Type Three (参式, Sanshiki): A fusion form accessed from the Repli Steamliner, Unicon, and Daiohni Replichemy Cards.
* Type Army (軍式, Gunshiki): Mass-produced versions of the Dreatrooper who utilize the DreaDriver (MP) (ドレッドライバー (MP), Doreddoraibā (Emu Pī)) belt. While normal-sized in the alternate timeline and act as enforcers to Glion's rule, the original timeline portray them as giants with gold converting powers.
* Type Final (終式, Shūshiki): Dread's ultimate form accessed from the Repli Gigantliner Replichemy Card. This form appears exclusively in the stage show Kamen Rider Gotchard: Final Stage.
The DreaDriver is voiced by Ryōtarō Okiayu (置鮎 龍太郎, Okiayu Ryōtarō).

### Ryo Kajiki

Ryo Kajiki (加治木 涼, Kajiki Ryō) is Houtaro's classmate and closest friend who believes that the supernatural exists. Due to his closeness to Houtaro, Kajiki is usually involved in several incidents related to the Chemy and the Kamen Riders, leading to his memories being frequently overwritten by Minato so that he could forget about them. However, such a procedure eventually puts such a strain in his mind that he recovers all his lost memories at the single sight of a Chemy or a Malgam. After high school graduation, he goes to university.
Ryo Kajiki is portrayed by Amon Kabe (加部 亜門, Kabe Amon).

### Tamami Ichinose

Tamami Ichinose (一ノ瀬 珠美, Ichinose Tamami) is Houtaro's mother who runs the family restaurant Kitchen Ichinose (キッチンいちのせ, Kitchin Ichinose).
Tamami Ichinose is portrayed by Yoko Minamino (南野 陽子, Minamino Yōko).

### Fuga Kudo

Fuga Kudo (九堂 風雅, Kudō Fūga) is Rinne's father and an alchemist who stole the Ride Chemy Cards a decade ago for reasons currently unknown, branded a traitor by the Alchemys Union, after discovering a dark conspiracy within the organization. Fuga remained hidden at the Ouroboros World (ウロボロス界, Uroborosu-kai) filled with alchemy formulas to protect the Chemies and GotcharDriver from falling into the wrong hands before entrusting Houtaro with the GotcharDriver and securing the Chemies as he is defeated by the Three Dark Sisters and creates homunculi in his image to act in his stead.

They were stolen away from the Alchemys Union by Fuga, who was forced to release them into the world after entrusting the Chemies' safety to Houtaro. Chemies who end up being exposed to malice-consumed humans are merged with that human to become a single corrupt humanoid monster called a Malgam (マルガム, Marugamu), with Gotchard extracting the Chemy from its host while purifying them. However, a human host with goodwill can merge with a Chemy into a purified version of their Malgam form anytime, even when their eponymous Ride Chemy Card is used by a Kamen Rider. If a Malgam merges with other Chemies, the host evolves their Malgam form into a hybrid Mixtus (ミクスタス, Mikusutasu) form that transforms the absorbed Chemy into a weapon-like state.
