"I am Ultraman Tregear. I have come to realize your dream."
- ―Self introduction.
"Don't act like some galactic guardsman! Who decided the light is justice?!"
- ―Tregear to Taro in Ultraman Taiga episode 1
"If your heart is weak, you'll fall into the darkness just like Belial did, even as an Ultraman. Just like my old friend..."
- ―Taro subtly hinting Tregear to Taiga.
"He appeared as an Ultraman, but his heart is dark cold. He meddled with various universes, exploiting the weakness of the hearts of its inhabitants and led their stars to destruction."
- ―Ultraman R/B Novel description.
Over 1,300 years ago, Tregear had altered the DNA of Reugosite, forcing the peaceful creature to go rampant, leading to its first battle with the three siblings from Planet Sanja.
Ultraman R/B The Movie: Select! The Crystal of Bond
Tregear was responsible for bringing Riku Asakura and Pega into R/B's Universe, leading to their meeting with the Minatos and summoning Bemstar and Gan Q to wreak havoc on Ayaka city. Tregear then contacted Yukio Toi, helping him realize his dream of destroying the world he hates, corrupting him into Snake Darkness in the process and sending him to Planet Hostar 21. Later on, Tregear approached Katsumi Minato, tempting with his desires and identity, transporting Katsumi to the same planet after showing him a scene of Mecha Gomora rampaging. Tregear then left Katsumi alone while Snake Darkness arrived on Earth through one of his portals.
During the final battle, Tregear finally shows up to back up Snake Darkness and was surprised with Ultraman Rosso's return though he easily drives everyone into a corner even when Ultrawoman Grigio appeared. Tregear and Snake Darkness continued having the upper hand until the Minato siblings fused into Ultraman Groob, joining Riku who transformed into Ultimate Final once more. After the battle, Tregear was apparently destroyed by Geed's Wrecking Nova. However, in the post-credits, Tregear has survived this experience and left Earth afterwards.
Ultra Galaxy Fight: New Generation Heroes
Tregear approached Ultra Dark-Killer at some point and requested him to create the Darkness Copies of the New Generation Heroes, for the sole purpose of "proving" the point that Darkness and Light are one and the same. While observing the ensuing fight of New Generation Heroes and League of Darkness in his magical space (魔法空間 Mahō Kūkan), Ultraman Ribut approaches him and prepares to apprehend the fallen Ultra.
Prior to the series, Tregear fought against the New Generation Heroes near the Land of Light and confronted his old friend Taro after defeating them all. Even when the Tri-Squad arrived and successfully striking Tregear several times, he reduced them into particles before charging at an enraged Taro.
Twelve years later, Tregear reappeared as the arch-nemesis of Ultraman Taiga and relentlessly targets him. While hunting down Taiga on Earth, he assumes the form of a man named Kirisaki, who calls down monsters such as Hellberus to do his bidding. He personally attacks Taiga simply to spite him and his human host Hiroyuki Kudo after Hiroyuki's former pet Guesra Chibisuke was spotted in Japanese waters. Tregear kills Chibisuke to further enrage Hiroyuki, before taking his leave. Tregear also turns Rento Kujo into his puppet to cause destruction as Galactron MK2, and hinders Ultraman Titas upon his return. Other than that, Tregear takes the chance to taunt and meddle with Ultraman Fuma after Deavorick (MB) is destroyed. At some point, he also hired Alien Gapiya Abel to get rid of Taiga and the Tri-Squad.
Tregear was surprised by Taiga's transformation into Photon Earth and went to challenge him, finding out that Taiga had improved into a much more competent fighter. After a short battle, Tregear left, expecting nothing less of the son of Taro.
Secretly, Tregear had been allowing Taiga to collect and use the Kaiju Rings, which slowly corrupted his soul. As the darkness floods him, Taiga becomes more reckless in battle, as seen during his battles against Gigadelos and Skull Gomora. When enough darkness had accumulated within Taiga, Tregear took the chance to corrupt him, shutting out Hiroyuki, Titas and Fuma in the process. Taiga becomes an unresponsive puppet which Tregear claims as his own partner, all just to spite Taro.
Hiroyuki sees Taiga in the darkness after he is knocked out by Kirisaki. Tregear suddenly appears and convinces Taiga to go further down the path of darkness, leading him to expel Hiroyuki from within himself. When Titas and Fuma tried to save him, Kirisaki summoned Hellberus and Night Fang from their Kaiju Rings to stop them, but Hiroyuki manages to get through and save Taiga, granting him his new form Tri-Strium. Enraged at the failure of his plan, Kirisaki transforms into Tregear to fight Taiga, but disappears after being hit by the Tri-Strium Burst. Descending into a fit of madness, he develops a hatred towards Hiroyuki and starts targeting him directly.
Kirisaki infiltrates the EGIS base and launches a mental attack on Pirika Asahikawa. He somehow sees a meteor-like monster flying through space by reading her mind, and sets out to bring it to Earth. Tregear awakens the soul of the planet, Ether, by using the drill on Alien Ghos' ship. This caused the Earth to give off a signal that brought the monster towards it.
Tregear is a sadistic and remorseless manipulator and/or trickster who deceives people by offering to "fulfill their dreams" as demonstrated on Yukio Toi; he had used the man's hatred towards the world to turn him into the kaiju Snake Darkness. Tregear demonstrates more of these qualities when disguised as Kirisaki. He sometimes prefers to watch from the sidelines as he triggers a chain of events that lead to despair and suffering in others, rather than outright cause them.
Tregear seems to have a contrary belief towards the idea of justice, given his amoral viewpoint of light and darkness.
Tregear also enjoys mocking the Tri-Squad, meddling with them with every chance he gets. He even taunts Taiga multiple times during their first fight on Earth and took his Flame Blaster head on, knowing that it would not hurt him. Tregear also calls him "son of Ultraman Taro" instead of acknowledging his name, which serves to further fuel Taiga's anger.
In lesser aspects, Tregear has also shown himself to have fun with his villainy as if only playing the part up to humor others. An example of this is when he gives a balloon to a little girl only to pop it a bit later.
He also shows some amount of disgust towards physical contact with aliens, at least with Alien Gapiya Abel. After shaking hands, Tregear immediately had to conjure a handkerchief to clean himself.
Tregear also does not believe in the power of bonds, which the New Generation Heroes have frequently relied on. He mocks the idea and is quite clearly sickened by even the mention of the word "bonds".
The only other individual that Tregear considers a true opponent is his former friend Taro. When in his presence, he drops his cocky attitude and becomes much more serious in both attitude and fighting style. However, that changes when Taiga's Tri-Strium form emerges. It enrages Tregear that Taiga was able to overcome the darkness through the power of bonds that, as previously mentioned, Tregear despises.

- Color Timer: Tregear, like most Ultra Warriors, possesses a Color Timer. However, it is kept concealed behind an X-shaped golden armor plate.
- Claws: Tregear possesses gold claws on his fingers.
Kirisaki presses the button at the top of the Tregear Eye to open it up, changing its design from Tregear's chest to his mask. He holds the device near his face and presses the button at the bottom, which causes the Tregear Eye to release a dark aura while his eyes shine a red light. Kirisaki then morphs into Ultraman Tregear and grows to giant size if he chooses to. Alternatively, he can also transform without the use of the Tregear Eye.
- Projection: Tregear can project himself through computer or television screens to communicate, and is even able to transport at least part of his body through. He does not have to be inside the device to do so.

It is capable of sending foes flying across a city. In Ultraman R/B the Movie, Tregear conjures a swirling energy rift that forms a five-pointed insignia, from which powerful electrical bolts are released.
- Trera Cheir Phos (トレラケイルポス Torera Keiru Posu): A dark blue electrical beam fired from Tregear's finger. "Cheir Phos" is Greek for "Hand Lightning".

- Claw Slashing: Tregear performs a slashing attack with his claws.
- Ultra Dynamite: A dashing attack in which Tregear is engulfed in flames, and explodes on contact. Its power seems to rival Taro's Ultra Dynamite. Unlike Taro's Dynamite, which takes the form of conventional red fire, Tregear's flames are bright blue.
- Palm Strike: Tregear discharges energy through the palm of his hand. It can send another Ultra flying.
Ultraman New Generation Chronicle
- In an interview with Yuma Uchida, he mentions that his first voice over as Tregear was the first commercial for the film. It wasn't until the actual recording of the film that Yuma managed to capture the impression of his character, which he portrayed someone who is "neither good nor evil".
- From the pamphlet of Ultraman R/B The Movie, Masayoshi Takesue (the main director of Ultraman R/B) confirmed that Tregear was going to be the next recurring Evil Ultra Warrior, succeeding Ultraman Belial.
- While Masayoshi's words were proven true, they were taken almost too literally, giving Tregear an origin which very similar to Belial's (both were former residents of Land of Light and were estranged from Father of Ultra and Taro).
- From the August monthly issue Terebi-kun magazine, it is explained that Tregear's true strength is sealed behind the gear that covers his Color Timer.
- In a twitter post, Tregear's Trera Ardiga was labeled as the Trera Ultigeyser. It could be that the former is a weaker variant of Tregear's finisher.
