Born from an egg summoned by Mothra in her old age, Mothra Leo hatched prematurely to help his mother battle the evil Desghidorah after he was unleashed from his ancient tomb. The young larva fought Desghidorah but was severely outmatched. Mothra saved her son before he was washed away in a flood triggered by Desghidorah destroying a dam, and carried him safely out to sea, where her strength finally failed her and she drowned. Leo desperately tried to save his mother, but to no avail. Determined to avenge her, Leo cocooned himself and emerged in his more powerful imago form, then engaged in a rematch with Desghidorah, defeating him and successfully sealing him back in his tomb. The following year, Leo traveled to the Nilai-Kanai Temple to battle the toxic monster Dagahra, only to be soundly defeated. However, the monster Ghogo sacrificed himself to revive Leo and transform him into the more powerful Rainbow Mothra. Rainbow Mothra then transformed into Aqua Mothra and destroyed Dagahra. A year later, Rainbow Mothra faced King Ghidorah at Mount Fuji to rescue the many children the space monster had kidnapped. King Ghidorah was far too powerful a foe for Rainbow Mothra and nearly killed him. The Elias used their remaining strength to send Rainbow Mothra back in time to the Cretaceous, so he could battle King Ghidorah while he was younger and weaker. Rainbow Mothra defeated King Ghidorah but was severely wounded in the process. Several Primitive Mothras encased Rainbow Mothra in a cocoon, where he remained until the present day. When King Ghidorah reappeared in the present, Rainbow Mothra emerged from his cocoon as the more powerful Armor Mothra, and engaged in a final battle with his foe. Armor Mothra was able to vanquish the King of Terror and free his prisoners, then shed his armor to become Eternal Mothra and returned to Infant Island with Fairy and the Elias.
Mothra Leo was also featured as a resident of Godzilla Island in the television series of the same name. The son of Mothra, Leo defended his younger sister Baby Mothra from hostile monsters such as Battra, and fought alongside Godzilla and his allies to defend the island. In addition, Mothra Leo and his various forms appear in other officially licensed media including video games and card games.

Mothra Leo is only ever referred to onscreen as Mothra (モスラ) in the Rebirth of Mothra trilogy. Most official Japanese sources call him New Mothra (新モスラ Shin Mosura) or Rebirth Mothra (新生モスラ, while others instead give him the name Mothra Excelled Shinsei Mosura) (モスラ・エクセルド. Mosura Ekuserudo) Two English variations of this name, Exceled Mothra and Excelled Mothra, are used in All Toho Monsters Pictorial Book. The name "Mothra Leo" (モスラレオ originates from the title of a Mosura Reo)song sung by the Elias in Rebirth of Mothra as the monster forms his cocoon and emerges as an imago. While this name is never spoken onscreen to refer to the character, it was widely adopted by both Japanese and English-speaking fans to refer to this incarnation of Mothra. The name was finally used officially to refer to the character in the Toho DVD release for Rebirth of Mothra II, though it was spelled with an interpunct (モスラ・レオ). The English spelling "Mothra Leo" is used for the character in the 2019 mobile game Godzilla Defense Force. Each of Mothra Leo's different forms after his imago stage has its own distinct name, although only Aqua Mothra is individually trademarked.
In Japanese, Mothra Leo's forms are denoted as Rainbow Mothra (レインボーモスラ, Reinbō Mosura) Aqua Mothra (アクアモスラ Akua Mosura) or Underwater Mode Mothra (水中モード・モスラ, Suichū Mōdo Mosura) Micro Mothra (ミクロモスラ Mikuro Mosura) or Aqua Micro Mothra (アクア・ミクロモスラ, Akua Mikuro Mosura) Light Speed Mode Mothra (光速モード・モスラ Kōsoku Mōdo Mosura) or Rainbow Mothra Light Speed Mode (レインボーモスラ・光速モード), Armor Mothra (鎧モスラ, Yoroi Mosura) and Armor Mothra Eternal (鎧モスラ・エターナル Yoroi Mosura Etānaru) or Eternal Mothra (エタナール・モスラ. Etanāru Mosura)
Additionally, Mothra Leo, including all of his forms, are given the subtitle Guardian Beast (守護神獣. Shugoshinjū) The 1998 video game Godzilla: Trading Battle also gives both the larva and imago forms of Leo the subtitle Guardian Deity of Greenery (緑の守護神. Midori no Shugojin)
The basis for the character of Mothra Leo originated with Kazuki Omori's screenplay for Mothra vs. Bagan, which featured Mothra's newborn larva appearing to assist its mother in the final battle with Bagan. As Rebirth of Mothra repackaged many concepts from this story, it also retained this plot point. However, whereas Mothra vs. Bagan ended with the adult Mothra dying after successfully sealing Bagan away, the new film would have the adult Mothra die during the middle of the film only for her larva to take her place for the final battle against Desghidorah. The larval Mothra was considerably revamped for this story, being given entirely new abilities that the character had never possessed before. In addition, the larva would now mature into an adult for the final battle, and this adult Mothra was also substantially different from its mother. The new more powerful Mothra would go on to become the primary focus of the subsequent two films of the trilogy.
Mothra Leo's larval stage was modeled by Takafumi Tanibuchi and Masayuki Kurahashi of Boncraft. As special effects director Koichi Kawakita was dissatisfied with the movement of the Mothra larva prop from Godzilla vs. Mothra, he requested that the new prop be able to move its body in a wave-like motion akin to a real caterpillar. Kawakita ordered an internal mechanism for the prop from Myuron, a company specializing in mechanical modeling. The prop was built with a gimmick which allowed different parts of its body to move up and down independently through the expulsion of compressed air inside of it. This allowed the prop to capture the realistic movement of an actual caterpillar. There were at least two separate Mothra Leo larva props created for the film, one of which was later refurbished and used for Mothra's larval stage in Godzilla, Mothra and King Ghidorah: Giant Monsters All-Out Attack.
Staff members from Rebirth of Mothra with two Mothra Leo larva props
Toho Special Art created two props for Mothra Leo's imago stage. They were modeled by Tsutomu Kobayashi, Naoki Nieda, Hideki Nomoto, Keyoji Nagata, Kumie Ishizaki, and Maki Kobayashi. To complement the more realistic model of Mothra Leo's larval stage, the imago props were given more realistic mouths than past Mothra designs. Staff members were told to only touch the imago Mothra Leo prop after they had washed their hands, as dirt from their hands would show up on the prop.
The Mothra Leo imago prop was reused for Rebirth of Mothra II. It was slightly modified and repainted in order to portray Leo's new form of Rainbow Mothra. In addition, a new prop was created for Leo's Aqua Mothra form. The design of Aqua Mothra was based on an unused design considered for a "high-speed flight form" for Mothra Leo in the previous film. Toho Special Art was again responsible for modeling Aqua Mothra. Its body was constructed from latex while its fins were made of vinyl chloride so that they appeared transparent. Aqua Mothra's "Illusion Mirage Aqua" ability he uses to defeat Dagahra was not in the film's screenplay, but was conceived during filming by Koichi Kawakita in order to differentiate the battle from that in the previous film. This was also Kawakita's way of finally realizing a battle within a monster's body, an unfulfilled idea he had for the scrapped Heisei Godzilla films Micro Super Battle: Godzilla vs. Gigamoth, Godzilla's Counterattack, Godzilla vs. Mechani-Kong, Micro-Universe in Godzilla, and a very early story for Godzilla vs. Mechagodzilla II. Naoki Nieda, Keyoji Nagata, Tsutomu Watanabe, and Maki Kobayashi were all credited for "Mothra Modeling" in the film, but it was not specified for which forms they were responsible.

For Rebirth of Mothra III, a new Rainbow Mothra prop was constructed to replace the previous one. Concept art for the new Rainbow Mothra design gave it various different color schemes and a more streamlined appearance, while the finished prop had more pronounced white fur with the rainbow colors on its wings replaced with a blue and orange color scheme. This prop was accidentally destroyed during filming of the scene where the Primitive Mothras encase Rainbow Mothra in a cocoon. The thinner used to create the Primitive Mothras' silk ignited during filming and set the Rainbow Mothra prop on fire, requiring the filmmakers to retrieve a new prop and film the scene again with it.

The Aqua Mothra prop from the previous film was also used briefly for the scene where Rainbow Mothra transforms into this form before becoming Light Speed Mothra. Unlike Mothra Leo's other forms, Light Speed Mothra was portrayed entirely through CGI rather than a prop. New props were created for Mothra Leo's final two forms, Armor Mothra and Eternal Mothra. Different color palettes and wing shapes were considered for Armor Mothra before the final prop opted for wings composed of a single piece with pointed tips and a silver, blue, and orange color scheme. Masayuki Kurahashi was credited for "Mothra Mechanical Production" on the film, while Tadashi Ogawa, Kenji Haraguchi, Motohisa Nagano, Masakazu Mukai, and Hajime Inui were credited for "Mothra Modeling." John R. Moot and Alan G. Thoday were credited for "Mothra Fur Production," and Makiko Akimoto and Kenichi Kuwajima were credited for "Mothra Mecha Production." As was the case for Rebirth of Mothra II, the credits did not specify the individual forms for which the staff were responsible.
The Armor Mothra prop is prepared for filming of the final fight scene with King Ghidorah.
Mothra Leo takes on many different forms and appearances over the course of the Rebirth of Mothra trilogy. In his larval form, Leo looks very similar to Mothra's larval form from Godzilla vs. Mothra, however he is lighter in color. After transforming into his imago form, Leo resembles his mother's imago form, but has several distinguishing features. His wings are somewhat more triangular and have different designs and color schemes. His abdomen is more rounded and less defined than Mothra's. Leo also has green eyes, three beads on his forehead, and feather-like antennae, resembling those of a male moth. After transforming into Rainbow Mothra in Rebirth of Mothra II, Leo's wings change from orange and green in color to all of the colors of the rainbow. As Aqua Mothra, Leo's appearance is more streamlined, and he lacks fur. Leo's wings are replaced with four fins, and he also gains fins on his tail.
In Rebirth of Mothra III, Rainbow Mothra's design changes. He now has a less bulky body, thinner legs, and backward-facing antennae. Leo's wings are a combination of blue, orange, black and white rather than all of the colors of the rainbow, and his eyes are blue rather than green. His form Light Speed Mothra looks almost identical to Aqua Mothra, but is blurry due to its quick movement. As Armor Mothra, Leo possesses a silvery armored shell around his body, with sharp jagged wings with different patterns. In his final form, Eternal Mothra, he looks very similar to Armor Mothra, only without the armored shell and with white fur all over his body.
Mothra Leo is a steadfast guardian of the Earth, charging into action whenever the Elias call upon him and fighting until his strength is spent, even against vastly more powerful foes. He is not above doing favors for individual humans as well, letting Taiki and Wakaba ride on him while he restored the Hokkaido rain forest, and clearing a path for the group who explored the Nilai-Kanai Temple to escape.
In the Rebirth of Mothra universe, Leo and Mothra were the last remaining members of a highly advanced species of giant moths created as guardians to the Elias, an ancient civilization of small yet powerful humanoids far older than humanity.
Leo first appeared as an egg laid by an aged and weakened Mothra in 1996. He hatched prematurely during a battle between his mother and a monster called Desghidorah and, despite being hopelessly outmatched in his larval form, attacked his mother's aggressor. After a long battle, the two managed to escape, though by that point, Mothra had been badly wounded, and she collapsed into the sea. Despite his best attempts to help her, Leo could do nothing as he watched his mother sink into the depths. Leo then retreated to a remote island where he cocooned himself against a 10,000 year old tree. After some time, Leo emerged as a swarm of multicolored butterflies which merged into one giant insect. Leo then flew to Hokkaido to do battle with Desghidorah, and arrived in a flurry of laser and energy beams. The demonic dragon could not stand against the power of the new Mothra and was soon defeated. With the help of the Seal of Elias, Leo imprisoned the beast once again within its ancient tomb. Leo then went on to replenish the land destroyed by Desghidorah, releasing a powder that sped up the growth of Hokkaido's flora. With the forests and fields returned to their original beauty, Leo returned to Infant island.
Mothra Leo was called upon again when an ancient pollution-eating monster called Dagahra began infesting the ocean with toxic parasites called Barems. Leo attacked Dagahra and seemed to have the upper hand, until the battle was taken underwater. Unable to combat Dagahra in his element, Leo was overwhelmed by a swarm of Barem and awaited his opponents' killing blow. However, with the assistance of the Elias, Mothra Leo was replenished by the water spirit Ghogo and was transformed into a new form, Rainbow Mothra (レインボーモスラ. Suffused with the water spirit's ancient magic, Rainbow Mothra re-entered the fray, relentlessly assaulting Dagahra. Yet, when the toxic one retreated below the waves, Rainbow Mothra followed suit and dove under the water, transforming himself into his new aqua form, Aqua Mothra Reinbō Mosura) (アクアモスラ, and finishing off Dagahra. With his foe defeated, Rainbow Mothra then flew off into the horizon and thus, the world is once again safe. Akua Mosura)
Rainbow Mothra was awakened again to fight King Ghidorah when he was eating humans. The two fought, but Rainbow Mothra was quickly defeated. Rainbow Mothra was transformed into Light Speed Mothra (光速モード・モスラ and went back in time to kill King Ghidorah when he was weaker. He went back to the Cretaceous period, where he fought Cretaceous King Ghidorah. He defeated Cretaceous Ghidorah, but his tail was buried in the ground. Cretaceous Ghidorah regrew from the tail, and arrived in the present only a day later. Leo attacked King Ghidorah as Armor Mothra Kōsoku Mōdo Mosura, lit. Light Speed Mode Mothra) (鎧モスラ, and killed him. Armor Mothra transformed into Eternal Mothra Yoroi Mosura) (エタナール・モスラ and flew away in peace.
The larval Mothra Leo was with his dying mother inside of a cave when a meteor crashed, which turned out to be Hedorah. Mothra, while still in bad condition, flew towards Hedorah and fought him, but Hedorah brought the aging Mothra down. Hedorah then went after Leo, but Mothra got back up and picked him up, then with her remaining strength flew to a volcano and dropped him into it. Now struggling to fly, Mothra fell into the volcano too. Leo then left and formed a cocoon. Hedorah turned out to be alive when he came back out of the volcano. Hedorah saw Leo's cocoon and went after it, but was distracted by Godzilla. Leo emerged from the cocoon in his imago stage, then teamed up with Godzilla to defeat him.
Mothra Leo possesses considerably more abilities than his mother, which often vary depending on which form he takes.
Mothra Leo can spray Excel Strings (エクセル・ストリングス Ekuseru Sutoringusu) from his mouth which have a multicolored electrical aftershock.
Mothra Leo can produce a blue-green blast of energy from his chest, called a Petite Railgun (プチ・レールガン. Puchi Rērugan)
Mothra Leo is able to create a Fake Reflection (フェイク・リフレクション, Feiku Rifurekushon) allowing him to blend in with his surroundings.
Mothra Leo travels on land at a typical pace of 40 km/h and maximum 60 km/h. He can also travel on water at 130 km/h.
After attaining his imago form, Leo can fly at speeds of up to Mach 15.5, though he can temporarily reach speeds of Mach 85 through an ability called the Excel Dash (エクセル・ダッシュ. Ekuseru Dasshu)
Mothra Leo can emit a trio of thin beams from the gems on his forehead, called Crossheat Lasers (クロスヒート・レーザー. Kurosuhīto Rēzā)
Excel Shining Field
By releasing a cloud of scales, Mothra Leo can create an energy field called the Excel Shining Field (エクセル・シャイニング・フィールド. Ekuseru Shainingu Fīrudo) Blue electrical energy may be discharged from this field.
Breast Power Beam
The Breast Power Beam is a powerful blue chest laser capable of sending Dagahra hurtling through the air and vaporizing large swaths of water.
Through the use of an ability known as Illusion Mirage (イリュージョン・ミラージュ, Mothra Leo is able to break apart into thousands of smaller, energized versions of himself called Crystal Mothras. Iryūjon Mirāju)
In a technique called the Sparkling Pileload (スパークリング・パイルロード, Supākuringu Pairurōdo) Mothra Leo can project arcs of electricity from his wings which then erupt into devastating pillars of energy. In Rebirth of Mothra II, these energy columns were instead created from a laser beam fired from Leo's chest and were powerful enough to send Dagahra hurtling through the air and vaporize large swaths of water.
Shine Strike Buster
Mothra Leo can perform a potent finishing move called the Shine Strike Buster (シャイン・ストライク・バスター, Shain Sutoraiku Basutā) in which he spins and flies upward into the air, raining circular blasts of energy onto a foe, before flying in a circle to create a giant lens with his scales, focusing the sun's solar rays into more destructive beams.
Mothra Leo is able to dramatically speed up the growing process of plants by releasing a Pulsaphonic Shower (パルセフォニック・シャワー onto them. Parusefonikku Shawā) He used this to return the Hokkaido rain forest to its original state in a matter of minutes.
In Godzilla Island, Mothra Leo can also fire red beams from his antennae.
