She was discovered by Kana 7 years prior to the series and was given a place in E.G.I.S.. After her boss Kana was rescued from Gorothunder, Kirisaki attempts to harass her in order to spite Hiroyuki but switched plans by summoning Woola after probing through Pirika's mind.

Ultra Warriors

The Tri-Squad (トライスクワッド, Torai Sukuwaddo) is a trio of Ultramen with different origins who join forces to preserve peace in space. Initially thought to have killed by Tregear, their scattered lights wandered in outer space as they reunite on Earth bonding with the same host, Hiroyuki.

Hiroyuki transforms into either one of them through the Taiga Spark (タイガスパーク, Taiga Supāku), an item which was developed by Ultraman Taro and Tregear and was originally his Taro-let (タロウレット, Tarō-retto). The item functions by scanning Ultra Taiga Accessory (ウルトラタイガアクセサリー, Urutora Taiga Akusesarī), each with different results:

• Key Holder Type (キーホルダータイプ, Kī Horudā Taipu): Represents the Tri-Squad's transformations.
• Bracelet Type (ブレスレットタイプ, Buresuretto Taipu): Powers of past Ultra Warriors, specifically the New Generation Heroes. It functions by empowering the Tri-Squad's finishing techniques.
• Ring Type (指輪タイプ, Yubiwa Taipu): Also called as Monster Rings (怪獣リング, Kaijū Ringu), it was created from remains of defeated monsters. Its mainly used by Taiga to tap into the monster's own power, but was carefully planned by Tregear as a way of influencing him through slow corruption.

Ultraman Taiga

Although the founder and leader of Tri-Squad, he yearns for his father's respect and grows to become a proper hero despite his youthful age, 4,800 years old.

In his younger days, Taiga found solace in the blue Ultra named Filis and trains harder after being overshadowed by his father's popularity. During his journey in outer space, he join forces with Andro Ares in Planet Maiji to fight against Imbeeza's platoon of Gua Army. He would soon meet Titas and Fuma within their respective homeworlds, which resulted in the formation of Tri-Squad. Following his defeat by Tregear, Taiga's particles of light wandered in space-time continuum and bonded with Hiroyuki to save the boy from a great fall. As his body recuperated in the span of 12 years, Taiga reveal himself to save the Zandrias family from Hellberus while dedicating his life to save Earth from multiple threats. Taiga grew stronger with his own set of powers, but slowly fell into the corruption induced from prolonged use of the Monster Rings. He was rescued by Hiroyuki and eventually gains a new form, Tri-Strium, as a result. After the battle against Woola, Taiga offered Tregear a chance of redemption, but was rejected and forced to defeat him with Quattro Squad Blaster.

At some point later on, Taiga found himself facing against his corrupted father and dealt with a reckless Hiroyuki. Riku give the Ultra an advice of facing one's father, and that only their son that could save them.

Taiga's fighting skill is balanced and utilizes the same stance as his father. His finisher is Strium Blaster (ストリウムブラスター, Sutoriumu Burasutā).

Taiga would later gain access to other forms in the series progress:

• Photon-Earth (フォトンアース, Foton Āsu): Taiga's power-up form, which he obtained through Ai Tennoji's help. His personal Key Holder was upgraded into Photon-Earth Key Holder (フォトンアースキーホルダー, Foton Āsu Kī Horudā) as Hiroyuki scans it thrice and empowers the Ultra with the energy of the Earth and Sun. Declaring himself as the "Hero of the Land and Sky" (大地天空の勇者, Daichi Tenkū no Yūsha), his body color becomes predominantly black and dons a set of gold and silver armor. His finisher in this form is Aurum Strium (オーラムストリウム, Ōramu Sutoriumu).
• Tri-Strium (トライストリウム, Torai Sutoriumu): Taiga's strongest form also known as the "Hero of Bonds" (絆の勇者, Kizuna no Yūsha) when Hiroyuki accessed the Tri-Squad-let (トライスクワッドレット, Torai Sukuwaddo-retto), combining with the rest of the Tri-Squad members and his human host. Taiga obtains the sword named Taiga Tri Blade (タイガトライブレード, Taiga Torai Burēdo), allowing him to utilize enhanced versions of the Tri-Squad members' finishing moves or his independent attack, Tri-Strium Burst (トライストリウムバースト, Torai Sutoriumu Bāsuto).

Unlike the rest of his kind, Titas is actually the son to a pair of Heller's Soldiers as he was jettisoned to the Planet U40 by his father, who wanted his son to follow a different path. During the Ultra People's final stand against the Heller Empire, Titas was hesitant in initiating Ultra Change until the death of Matia triggered his first transformation and killed the monster Kishiadar. Titas met Taiga when the latter visited U40 and later on forms the Tri-Squad after Fuma joined them.

Following his defeat from Tregear, Titas' particles of light roamed in outer space and assisted the spirit of Nana Kujō to stop her vengeful husband from destroying Cozmo Technica. After fulfilling her wish and stopping Galactron MK2, Titas bonded with Hiroyuki as he reunited with Taiga.

With his carefully trained body and healthy spirit, Titas is skilled in heavyweight battles. Being an Ultra Person of U40, Titas bears a Star Symbol (スターシンボル, Sutā Shinboru) that he obtained by the Great Sage but operates normally like a Land of Light Ultra's Color Timer.

Prior to the series, Fuma was originally a human-like son of a climber who gave up halfway to the Warrior's Peak of Planet O-50. He was born on said planet as his father was incapable of returning to his home world out of embarrassment. While making his living as a street child, the boy received tutelage under an alien named Gerg and the two since then took various odd jobs in hopes of being recognized by O-50's Ring of Light. After being injured by the Interstellar Alliance due to being tricked into fighting his mentor, Fuma was brought to the Warrior's Peak and becomes an Ultraman in order to save his life. He had since remain as an Ultraman to honor Gerg. Fuma would meet Taiga and Titas when his home world was under attack by alien forces and together, the three defend the Warrior's Peak and form the Tri-Squad.

After his seeming death from Tregear, Fuma's particles entered a jewelry which passed on to various users, with the recent owner being the Villain Guild itself. Volk stole it in hopes of selling it to support the impoverished alien children before Fuma escaped to fight Darebolic and rejoin the Tri-Squad.

He has a rough personality, but also a strong sense of duty. Fuma utilizes speed and agility during combat, as well as firing energy shuriken. His finisher is Polar Star Light Wave Shuriken (極星光波手裏剣, Kyokusei Kōha Shuriken), which is said to be taught by his alien instructor Gerg even before his transition into an Ultra.

Antagonists

Ultraman Tregear

Ultraman Tregear (ウルトラマントレギア, Urutoraman Toregia) is the main antagonist of Ultraman Taiga, who menaced the Tri-Squad on recurring occasions and at the same time taking pleasures on others' misery. While blending in with society, Tregear took on the human alias Kirisaki (霧崎).

Originally an insecure Blue Tribe (ブルー族, Burū-zoku) member of the Ultra race from the Land of Light, Tregear became fast friends with Ultraman Taro, but their friendship grew apart when they went to separate career paths. Discovering the reason behind Belial's rebellion against his own people and his supervisor Hikari embarking on a vendetta against Bogarl, Tregear became disillusioned with the Land of Light's policy as a peacekeeper and went on a self-imposed exile. Eventually by absorbing Grimdo into himself, Tregear severed his Ultraman heritage and embraced the darkness, using his newfound powers to sow chaos in 7 universes. Tregear was also responsible for the events of Ultraman R/B taking place, as well as fighting the Minato siblings at one point.

Having initially assisted the League of Darkness from behind the scenes, Tregear faced off the New Generation Heroes by incapacitating them on an asteroid, then dispersing the Tri-Squad into light particles to be scattered onto Planet Earth. 12 years later, Tregear observed the Tri-Squad's reunion and clashed fists with them, but his true plan came to light as he was slowly corrupting Taiga into an evil Ultra. When Taiga managed to overcome the corruption with Hiroyuki and Tri-Squad's help, Tregear resorted to summon Woola to devour Earth. His attempt to sabotage Taiga and EGIS' operation backfired when his energy beam was used as a catalyst to feed Woola and ended the monster's life in a painless way. After rejecting a chance of redemption, Tregear allowed himself to be seemingly obliterated by Taiga Tri-Strium's Quattro Squad Blaster. Six months later, his previous defeat from Tri-Strium resulted with an accidental release of a fragment of Grimdo. The rest of Grimdo remained sealed within Tregear's body and the fallen Ultra used said monster to possess Taro on Earth, creating a conflict between both father and son in the midst of the New Generation Heroes' appearances. Taiga Tri-Strium successfully saved Taro by performing Ultra Dynamite, but Tregear allows himself to be consumed for Grimdo to restore its full power. After the ancient god's defeat by Reiga, Tregear was last seen whispering Taro's name as he died in the explosion.

Originally in his Early Style, Tregear is far weaker than an average Ultra, but makes it up with his high intellect, one of which resulted with the creation of the Taiga Spark that members of Tri-Squad came to use. After forming a pact with Grimdo, Tregear's body is partially wrapped with restraints and a cover on his Color Timer to keep the monster's seal intact. Grimdo's powers allow Tregear to endlessly operate without limitations and creating Trera Thyra (トレラ・スラー, Torera Surā) space portals to multiple dimensions. Aside from the finishing move Trera Ultigeyser (トレラアルティガイザー, Torera Arutigaizā)and corruption-inducing beam Ischyros Dynamis (イスキュロス・ダイナミス, Isukyurosu Dainamisu), he can cheat death from fatal attacks by having an alternate universe counterpart replacing his original body.

Grimdo

Malicious Demonic Monster Grimdo (邪神魔獣 グリムド, Jashin Majū Gurimudo) is the final villain of Ultraman Taiga The Movie. Long ago, Grimdo existed as a primordial deity since the era of chaos and was sealed within Planet Borges (惑星ボルヘス, Wakusei Boruhesu) to maintain the balance of the universe. During Tregear's self-exile from the Land of Light, he freed Grimdo from its prison and form a pact by absorbing the monster into his body, with a set of restraints keeping its presence at bay. With Grimdo's nigh-omnipotent powers, Tregear strength surpassed even a Super Ultraman and is capable of using bodies of his alternate selves as backups to cheat death.

After his defeat by Ultraman Taiga Tri-Strium's Quattro Squad Blaster, the seal broke and a fragment of Grimdo was temporarily sealed through the New Generation Heroes after sacrificing their transformation powers. Six months later in Ultraman Taiga The Movie, Grimdo was unleashed from its seal and possessed Ultraman Taro during his attempt on using Ultra Dynamite, placing him under Tregear's control. When the Tri-Squad expelled Grimdo from Taro, Tregear allowed the ancient god to consumed him to restore its full power as it fought against and was defeated by Ultraman Reiga's Reiga Ultimate Blaster.

After it was unleashed from Tregear's restraints, Grimdo was only half of its original strength, as the other half remained in the fallen Ultra. To restore its full power, Tregear offered himself as a sacrifice in his desperate bid to kill Taro and the New Generation Heroes, as it grew large and has the ability to terraform Earth into a similar environment to Planet Volhes.
