Protagonists

Ultraman Leo

Ultraman Leo (ウルトラマンレオ, Urutoraman Reo) is the titular protagonist of his series, who took on the appearance of 20-year-old Gen Ootori (おゝとり ゲン, Ōtori Gen)^[a] and worked as an instructor of Jonan Sports Center. In contrast to the previous Showa Ultras, Leo's home world was the Planet L77 of Leo Constellation (獅子座L77星, Shishi-za Eru Nana-ju Nana Sei) instead of Land of Light in Nebula M78.

Leo was one of the survivors of his home world's destruction by the hands of Alien Magma and his Giras monsters. Ever since adopting a human identity, Gen views Earth as his second home and committed to defend it no matter the cost. Having rescued Seven from Alien Magma, Gen was enrolled into MAC as their seventh member and took over the former's mission to fight against monster threats. Despite his new job, Gen was still permitted to visit Jonan in his free time. Being an Ultraman in disguise, Gen displays excellent body performance and senses but due to his young age, he is prone to make irrational decisions and would even pick a fight with others. However, Gen builds up a character development as the series progressed thanks to his interaction with humans and training provided by Dan, as well as protecting Earth while maintaining friendship with MAC members. By the time MAC was annihilated in episode 40, Gen and Toru live with the Miyama family as they team up to investigate Saucer Monster attacks through his previous experiences. By the end of the season, Gen bids farewell to Toru as he left traveling on a yacht.

As Ultraman Leo, Gen transforms with the Leo Ring (レオリング, Reo Ringu) on his left hand.^{[b][2][3][4][5]} Being an Ultraman from another world, Leo's time limit on Earth is 2 minutes and 40 seconds, while his abdomen bears the Secret Sign (シークレットサイン, Shīkuretto Sain) that functions as coat of arms for L77 inhabitants.^[6] As an Ultraman who uses martial arts proficiency in combat (Karate and Space Kenpō (宇宙拳法, Uchū Kenpō)), Leo's main finishing move is Leo Kick (レオキック, Reo Kikku), a flying kick attack with multiple variations of it shown in the series progress.^[7] He can also perform beam finishers, such as Leo Cross Beam (レオクロスビーム, Reo Kurosu Bīmu), Dark Shooter (ダークシューター, Dāku Shūtā) and Shooting Beam (シューティングビーム, Shūtingu Bīmu).^[8][9] He can also wield weapons in combat:

• Leo Bracelet (レオブレスレット, Reo Buresuretto): A bracelet that allows him to utilize a syringe in episode 18.^[10]

Tooru Umeda

Tooru Umeda (梅田 トオル, Umeda Tōru)^[c] is a 10 year old recurring character who eventually becomes the supporting protagonist. One of the students of Jonan Sports Center, Tooru views Gen as an older brother, especially after being orphaned by Alien Tsuruk and was adopted by Momoko alongside his younger sister Kaoru. With Kaoru and his friends from Jonan Sports Center were killed by Silver Bloome, Tooru lives with the Miyama family. The loss of his family members and his close friends nearly drove Tooru to the point of despair, which Nova exploited but slowly moves on with Gen's moral support. In the final episode, Tooru discovered Gen's identity as Ultraman Leo and was held captive by Commander Black as a leverage for Leo in against Black End until several children that Gen tutored freed him as they beat Commander Black to death. Tooru bids farewell to Gen as they parted ways.

Astra first appeared in episode 22 to help Leo in fighting against monster siblings Gallon and Litter. Ever since then, he would appear to help his brother in occasional moments. In a two parter episode 38–39, Astra was left frozen and impersonated by Alien Babarue to steal the Ultra Key from the Planet Ultra and put it on a collision course with Earth. Ultraman King would later on expose Babarue's deception, allowing Leo to save his younger brother and undo the damages his impostor had made.

When Alien Babarue posed as Astra to stir up the conflict between Leo and the Ultra Brothers, King interfered and exposed Babarue's treachery as he broke the Ultra Key while informing Leo of Astra's actual location.

Antagonists

Alien Magma

Sabre Tyrant Alien Magma (サーベル暴君 マグマ星人, Sāberu Bōkun Maguma Seijin, 1, 2, 30) is an evil alien who had destroyed countless planets, including Leo's home world L77.^[29][30] Despite his notoriety, Magma is not very adept in actual battles and only participate when his monsters Red and Black Giras are dominant. In episodes 1 and 2, he is the black-caped Heavy Armed Type (重武装タイプ, Jū Busō Taipu), equipped with a 25-meter-long pata Magma Saber (マグマサーベル, Maguma Sāberu) that can fire Laser Ray (レーザー光線, Rēzā Kōsen) on his right arm and Magma Hook (マグマフック, Maguma Fukku) on his left arm.^{[29][31][32][33][34]} Alien Magma had sent both the Giras twins on Earth to sink Japan, fighting against Seven before Leo appeared to save him. In his second appearance, Leo's necessity for vengeance against Magma caused him to lose the fight. When Leo finally killed the Giras twins in their final confrontation, Magma was forced to retreat.

In episode 30, Alien Magma returned in an attempt to court the beautiful monster Rolan. While assaulting her for refusing his proposal, Gen in Maccy 3 opened fire to give Rolan a chance to escape. Magma would shrunk to human size and hunt several kids who possessed pinwheels made by Rolan. When Rolan was about to leave Earth, Magma tried to kill her as penance for refusing his proposal until Leo interfered, using her pinwheel to pierce through Magma's heart, finally avenging his parents on Planet L77. While lacking the mantle, Magma retained the same abilities and weapon as first episode in addition to Arrow Ray (アロー光線, Arō Kōsen), shooting a stream of needles from his hand.^[29][35]

The Alien Magma in episodes 1 and 2 is portrayed by Yoshihisa Uragami (浦上 嘉久, Uragami Yoshihisa).^[36] The identity of the Alien Magma in episode 30 is ambiguous, as the episode itself and magazine Ultraman Pictorial: Warrior of Light's 35 Years Steps (ウルトラマン画報 光の戦士三十五年の歩み, Urutoraman Gahō Hikari no Senshi Sanjūgo-nen no Ayumi) claimed him to be the same Magma from episodes 1 and 2 whereas other magazines would contradict this theory.^{[29][35][37][38]}

Ultra Killer Gorgo

Hitman Alien Ultra Killer Gorgo (殺し屋宇宙人 ウルトラキラーゴルゴ, Koroshiya Uchūjin Urutora Kirā Gorugo) is an alien bounty hunter known for his reputation in outer space. According to Dan and Kotaro, Gorgo is powerful enough to kill an Ultra Warrior, so much so that only Ultraman Ace's Space Q can kill him. Gorgo was hired by Alien Magma to kill Ultraman Leo in exchange of a planet under his rule. When Magma was discovered threatening Leo with his comrades at Jonan Sports Center, Gorgo forfeited the match and decided to fight Leo under fair terms, going as far as to allow his opponent to bring an ally with him as penance from earlier. Unfortunately this become his undoing as Dan summoned Kotaro, who becomes Taro and performed Double Strium Ray against Gorgo to kill the bounty hunter.

Alien Babarue

Dark Alien Alien Babarue (暗黒星人 ババルウ星人, Ankoku Seijin Babarū Seijin, 38, 39) is the ruler of the dark universe (暗黒宇宙の支配者, Ankoku Uchū no Shihai-sha) who was the feared opponent of the Ultra Brothers, having targeted the Planet Ultra and fought them in numerous occasions.^[29][39][40]

After freezing Astra, Babarue took the form of Imit-Astra (にせアストラ, Nise Asutora) and steal the Ultra Key (ウルトラキー, Urutora Kī) to send the Land of Light towards a collision with Earth.^[41][42] When the Ultra Brothers arrived on Earth, Imit-Astra deceived Leo into protecting him from the Ultra Brothers, to the point of being a forced meat shield from their combined attack until Ultraman King arrived and exposed Babarue's true identity, breaking the Key so he couldn't use it for its alternate purpose, a superweapon capable of blowing planets to pieces with a single shot. As the Land of Light continued on its course to Earth, Babarue's plan almost came to fruition, but Leo rescued Astra, commencing the plan to save both planets. While Astra took the Ultra Key to the Land of Light to be repaired and reinstated, Leo faced Babarue in battle and destroyed him, ending the alien's plans for the destruction of Earth and the Land of Light.

Babarue's main weapons were a Kusari-fundo launched from his left arm and a retractable arm cutter on his right. He can also perfectly disguise as an Ultraman without any traces of flaws.

Alien Babarue is voiced by Motomu Kiyokawa, who also voiced King the same episodes that the former appeared. Meanwhile, his disguise as Astra is voiced by the former's voice actor, Junji Maruyama.^[23]

Commander Black

Commander Black (ブラック指令, Burakku Shirei, 40-51)^[d] is a mysterious man clad in black clothing who commanded the Saucer Monster attacks on Earth. Commander Black is notable for being the first and only antagonist in the Ultra Series to completely wipe out a human team, using Silver Bloome to kill and consume almost everyone in MAC, with only Dan and Gen escaping with their lives. Although his reason to invade Earth was never specified, the 2001 magazine Kokoro ni Ultraman Leo (心にウルトラマンレオ, Kokoro ni Urutoraman Reo, Within Ultraman Leo's Heart) reveals that Commander Black invaded Earth to avenge Babarue's death, with his position as an invader is bigger than Alien Magma.^[45]

With the crystal ball in his possession, Commander Black directed his Saucer Monsters from Black Star to invade Earth. However, as all of them were beaten by Ultraman Leo, Black summoned his last Saucer Creature Black End to challenge Leo into a final showdown and kidnap Tooru as his hostage until a group of children led by Ayumi attacked him. Tooru would later be freed and threw Commander Black's crystal ball to Leo, who used it to defeat Black End. With his Saucer Monster destroyed, Commander Black was reduced to a pile of bubbles in his final breath.

Commander Black is portrayed by Takeshi Ōbayashi (大林 丈史, Ōbayashi Takeshi).^[46]

Saucer Creatures

The Saucer Creatures (円盤生物, Enban Seibutsu, 40-51)^[e] are a type of Kaiju deployed from the demonic planet Black Star (ブラックスター, Burakku Sutā).^[44] Through Commander Black's crystal ball, the Black Star would send a Saucer Monster as Leo destroyed them one-by-one. When Black End, the final Saucer Monster defeated, the Black Star try to destroy Earth on a collision course until Leo destroys it with Shooting Beam. Following the destruction of Black Star, Roberuga (ロベルガー, Roberugā) - a new Saucer Monster unrelated to the original set but connected to them by being formed from the wreckage of Black Star - appears in Ultraman Mebius, which takes place 34 years later in the main continuity's timeline.

With the exception of Bunyo, they are shown to be a composite of Earth creature and astrobiology. Befitting their race, they can turn themselves into flying saucers for easy transportation. Several of them can shrink into the size of humans, allowing them to blend in the human society unnoticed as Leo would only take action upon their return to actual sizes. The destruction of MAC by Silver Bloome leaves Earth with no means of countering alien invasions. Each Saucer Monster displays a different level of intelligence:

• Silver Bloome (シルバーブルーメ, Shirubā Burūme, 40):^[f] The first Biological Saucer to appear, designed after a jellyfish and a Japanese wind chime.^[44] It attacked the MAC Station and a shopping mall in Shinjuku, killing Gen, Dan and Tooru's close friends. At some point of time, Kameda and two of his friends picked a shrunken Silver Bloome as they brought it to school. Tooru and Ayumi recognized it as the same monster that killed his friends but their words fell on deaf ears. At night, their homeroom teacher accidentally provokes Bloome as it devours him and proceeds to attack the school on the next day. During that rainy day, Leo appeared and stop it long enough for the faculties to rescue the students as he brutally disembowelled the Saucer Beast, pulling out its intestines, and some undigested pieces of the MAC Station that Silver Bloome had not finished eating (including Maccy 2 and 3) before finishing it with Spark Ray.

Jackal

Demonic Space Overlord "Demon King Jackal" (宇宙大魔王 ジャッカル大魔王, Uchū Daimaō Jakkaru Daimaō) is the antagonist of 1975 manga, The Ultraman, illustrated by Mamoru Uchiyama.

The leader of the eponymous Jackal Army (ジャッカル軍団, Jakkaru Gundan), Jackal was banished into the black hole by Ultraman King for his crimes against the universe. Unfortunately, the black hole itself empowers Jackal long enough for him to escape and lead his army in an attempted genocide against the Ultra Warriors, forcing the survivors to take refuge on Earth. On Earth, members of the Jackal Army try to force Zoffy into surrendering himself, but the recent arrival of Melos turn the tides of the battle and lead the surviving Ultras into storming Planet Jackal and attacked their leader. The Demon King Jackal managed to defeat Melos by feigning surrender but Zoffy dons the Cosmo Tector to mislead the Jackal Army, allowing Mother of Ultra to revive the fallen Ultra Brothers and obliterate the Demon King. With peace returning to the universe, the surviving Jackal Army ceased fighting and surrender themselves.

The Demon King Jackal is capable of assuming various forms to assassinate the Ultra Warriors; Zetton in against Ultraman, Alien Nackle and Black King against Returned Ultraman, Ace Killer against Ace, Birdon against Taro and Zoffy against the Leo Brothers.

As with all male characters, Demon King Jackal is voiced by Koichi Yamadera when The Ultraman was adapted into a 2015 short animation.
