List of Ultraman Omega characters

This is the character list of 2025 Ultra Series Ultraman Omega.

The Kaiju Special-Countermeasure Team (怪獣特別対策隊, Kaijū Tokubetsu Taisaku-tai), abbreviated as KSCT (怪特隊, Kaitokutai), is a special team that was formed to protect the public from monster appearances. It has headquarters in the Ministry of Disaster Defense (国土防災省, Kokudo Bōsai-shō) and nine teams stationed across Japan. Sorato, Kosei, and Ayumu later join the KSCT Unit Uta (ウタ班, Uta-han), officially known as the KSCT Special Task Unit (特務班, Tokumu-han), which is Sayuki Uta's own special operations team that is separate from the other nine teams.^[1][2] A year after Zomera's destruction, an international monster response organization known as the Kaiju Science Special Investigation Team (怪獣科学特別捜査隊, Kaijū Kagaku Tokubetsu Sōsa-tai), abbreviated as KSSIT, was established to work on coexisting with Earth monsters.

Sorato Okida (オオキダ ソラト, Ōkida Sorato)^[a][b] is an amnesiac man and the human identity of Ultraman Omega (ウルトラマンオメガ, Urutoraman Omega).

His true identity is originally one of the Space Gazers (宇宙観測隊, Uchū Kansoku-tai) who watch over planets with advanced civilizations to record everything from the birth to the death of the civilizations and seek to use those records to achieve true, unending peace. He intervenes on the moon when Genessians made their move to take the planet for themselves, eventually ended up with his current predicament after being defeated by Zovaras. While spending time as "Sorato" and eventually recruited into KSCT, Omega begins to warm up to mankind itself and saving them from countless attacks, both terrestrial monsters and extraterrestrial threats. After the revelation from Ahdel, Sorato regains his memories and eventually returns to his role as a Space Gazer, forcing him to reclaim his Meteokaiju from Kosei in the process. By the time Zomera's reign of terror reached the city, Sorato regains his actual resolve to defend humankind, absorbing Kosei as his human host and together defeating the chimeric monster. A year later, Sorato remains bonded to Kosei as another Space Gazer replaced him as Earth's watcher, thus allowing Omega to continue his duty as Earth's defender whilst humankind slowly finds a way to peacefully coexist with monsters.

Because of his role as a Space Gazer, Sorato has knowledge of terrestrial monsters that persisted even in his days spent as an amnesiac.^[3] As Ultraman Omega, Sorato transforms with the Omega Slugger (オメガスラッガー, Omega Suraggā) and the Omega Meteo (オメガメテオ, Omega Meteo) crystal. His finishing move is Reticulute Beam (レティクリュート光線, Retikuryūto Kōsen). His main weapon is a boomerang blade on his head, which has the same name as his transformation item.^[4][5]

Kosei Hoshimi (ホシミ コウセイ, Hoshimi Kōsei)^[a] is a 21-year-old freeter who works part-time as a live-in warehouse caretaker.

He encounters and befriends Ultraman Omega and gives the alien his human name Sorato Okida. As Sorato continuously fights against the growing monster threats, Kosei gains the power to control Omega's recovered Meteokaiju.^[10][11] This allows Kosei to actively support Omega in battle by directing the Meteokaiju or allowing Omega to arm himself with his old monster companions. When Zomera threatened the city, Kosei's attempt to jumpstart the Kaen 102 to destroy the monster costed him his life, but Sorato/Omega made the compromise by absorbing Kosei as his human host, allowing Kosei to survive and transform into Ultraman Omega. A year after Zomera's destruction, he joins the KSSIT Tokyo branch as Ayumu's assistant, where Sorato remains in Kosei for his body's full recuperation while granted access to Omega's form and powers despite humankind's growing effort at peacefully coexisting with the native monsters.

The Genessian (ゲネス人, Genesu-jin) are an unseen race of aliens from Planet Geness (ゲネス星, Genesu-sei) who fled their home planet after it was ravaged by monsters in the time of awakening (目覚めの刻, Mezame no Toki). With its ecosystem forever destroyed from the conflict, the Genssians built a space fortress on the Earth's Moon where they intend to invade the planet as their replacement home planet in the event when its own time of awakening reached as well. However, their actions caught the attention of Ultraman Omega as he destroys their facility and the guarding Vugsects before he fell to Earth as a result of Zovaras. The Genessians had since extinct, their essences live on in Zovaras.

He is portrayed by Yukijirō Hotaru (螢 雪次朗, Hotaru Yukijirō).^[14][3]

Annihilative Proliferation Monster Zomera (殲滅細胞怪獣 ゾメラ, Senmetsu Saibō Kaijū Zomera) is an artificial monster born from the fusion of Zovaras's and Eldeghimera's cells. Originally, NDF scientists within Ogasawara Islands try to study the cells of both Zovaras and Eldeghimera's Ghimera Cells. After both researches hit a wall, they try to combine both cells despite protests from Sayuki Uta, but the end result gave birth to Zomera by accident. It fought and devoured Gairyuga and Demaaga in two separate encounters before Ultraman Omega intercepted the chimeric monster, but was forced to retreat after it tries to brainwash Valgeness, forcing the Ultra to recall the monster at the last moment. Arriving on Japan and devouring Gomora, it faced against the combined might of NDF and KSCT trying to use the weaknesses of Eldeghimera and Zovaras, only for the monster to surpass it with its continuous growth in strength. Zomera was destroyed by Omega's Reticulute Beam.
