Mega Man Star Force, known as in Japan, is an anime and manga series based on the video game of the same name. The series follows the adventures of Geo Stelar and Omega-Xis, a duo capable of em wave change to become the hero "Mega Man". Together, they combat various EM wave beings that threaten to conquer or destroy the Earth.
The manga was serialized in CoroCoro Comic beginning in September 2006, three months before the game's Japanese release. The anime series premiered in Japan on October 7, 2006, shortly after the conclusion of MegaMan NT Warrior. The anime concluded on March 29, 2008, with a total of 76 episodes. The anime was licensed and adapted into English by Viz Media. The English version first premiered online on the streaming service Toonami Jetstream on July 23, 2007, before making its television debut on Cartoon Network on August 25, 2007.
History Airing October 7, 2006 on TV Tokyo, the Ryūsei no Rockman anime filled the timeslot that had been held by Rockman EXE Beast+, the series' predecessor. Each of its episodes are approximately ten minutes in length as the program shared the thirty-minute segment Oha Coliseum with the Saru Getchu anime series.
On April 17, 2007, VIZ Media announced that they acquired the rights to the anime series, which would be released under the title Mega Man Star Force, as with the namesake video game. The press release mentioned that 13 episodes were to be released at lengths of 20 minutes each (each containing content from approximately two of the quarter-hour length Japanese episodes). During the E3 2007 video-game convention, IGN revealed in their hands-on impressions of the Star Force video game that the English version would premiere on Toonami Jetstream on July 23, 2007. The show made its television debut on Cartoon Network on August 25, 2007, edited as a two-hour presentation composed of scenes from the first nine Japanese episodes. Voice recording for the series was handed by Studiopolis.
According to the September 2007 issue of CoroCoro Comic, the anime would conclude in Japan on October 27, 2007, and be succeeded by a sequel series, titled Ryūsei no Rockman Tribe, premiering on November 3, 2007. The second anime is loosely based on the events of the second game in the series. According to an interview with Fuyuka Oura (Geo's voice actor in the Japanese version) at the 2007 Tokyo Game Show, Tribe has a deeper and "cooler" storyline than before, and the new character Solo is a prominent character in the plot.
Manga Entertainment released all thirteen episodes of the English version in a Region 2 box set in the UK on November 3, 2008. The English dub series was later added to Viz Media's Neon Alley series on June 1, 2015.
On December 17, 2025, Capcom started uploading episodes of the series in both languages on their YouTube channels to promote the release of Mega Man Star Force Legacy Collection (2026). The cast of the anime reprised their respective roles for the game.
Production
Mega Man Star Forces animation is overseen by XEBEC, with musical arrangements by Naoki Maeda. Character designs (which have in some cases deviated from Capcom's original concepts) are handled by Mitsuru Ishihara and Shingo Adachi (who is also one of the series' art directors, some of the others being Masayuki Nomoto, Akira Takahashi, and Yasuo Shimizu). The art directors usually work independently of each other on any given episode. Shogakukan manages computer-generated imagery.
The original Japanese openings are for the first series, and for Tribe, both sung by Misora Hibiki / Sonia Sky.
Plot
The year is 220X. Technology has advanced rapidly since the age of the internet, leading to the creation of new and more efficient modes of transportation, as well as the construction of futuristic cities, all linked together by three satellites orbiting the Earth—Pegasus, Leo, and Dragon. The satellites accomplish this by maintaining a network of EM waves around the planet's atmosphere, thereby powering the invisible EM Wave World. The human population carries portable devices called Transers to interface with the EM Wave World and other electronic devices. Problems caused by criminals and EM Wave Viruses manipulating the EM Wave World are commonly dealt with by the Satella Police.
Original series
A proud warrior of the FM Planet, Omega-Xis, betrays his kind and escapes to Earth where he makes contact with Geo Stelar. Like his fellow extraterrestrials called FM-ians, Omega-Xis is capable of initiating a process known as "Electromagnetic Wave Change," which transforms ordinary humans of the same frequency as themselves into "EM Wave Humans," allowing them to freely operate in the EM Wave World. With these new powers, Geo becomes known as Mega Man, a hero of Echo Ridge. However, Omega-Xis holds the key to accessing the weapon Andromeda, capable of destroying planets. As such, many FM-ians pursue Omega-Xis with the intent of retrieving the key in their goal to destroy the Earth. Meanwhile, Omega-Xis also knows the secret to the disappearance of Geo's father in a catastrophic space accident months ago.
The first half of the series focuses on the FM-ians hunting Omega-Xis for the Andromeda Key. Eventually, they succeed, but by using Star Force, Mega Man is able to sustain Andromeda and destroy the key. In the latter half of the series, the FM-ians band together, taking the guise of their original human counterparts, and seek a way to energize a new Andromeda Key. Eventually, Gemini Spark takes the reins of the operation and succeeds in reviving Andromeda, but the FM-ian king Cepheus descends onto Earth to put a stop to all of the chaos. Geo also has an encounter with his father Kelvin who reveals that he has become an EM wave being and is still exploring space, and that Geo's place is on Earth, fighting for justice as Mega Man.
Tribe
The second series follows the events of the second game focusing on the lost continent of Mu. The ancient civilization vanished ages ago, and a few of its remnants still exist as myths and legends called UMAs (Unidentified Mystery Animals similar to FM-ians that also have the ability to fuse with humans). The UMAs begin merging with humans in order to search for the treasures of Mu, the powerful OOPArts, which will give them the power to revive Mu. After Geo and Omega-Xis encounter several unusual enemies, they meet a professor named Doctor Vega who sends them on a quest to find the OOPArts and stop the UMAs. Using the OOPArts, Mega Man is able to take new forms, primarily the sword-wielding Thunder Zerker form. Near the end, Geo discovers that Doctor Vega and her accomplice Hollow are manipulating Geo to use the OOPArts for the revival of Mu and the devastating force known as Le Mu. But Mega Man combines the three OOPArts together, forming Tribe King, and uses this new power to stop Le Mu and seal Mu once more. The series premiered November 3, immediately after the original series' conclusion, and concluded March 29, 2008.
Characters
Geo Stelar and Omega-Xis Geo Stelar: Omega-Xis:
Geo Stelar, known as in Japan, is the main protagonist of the Star Force series. A gentle but a bit lonely fifth-grade student, Geo mourns the disappearance of his father that occurred three years prior, and has neglected school as a result. After being confronted by his classmates who pester him to return to school, he heads to an observing platform where he discovers the survivor AM-ian Omega-Xis by donning the Visualizer glasses left to him by his father, which allows him to view the EM Wave World. Omega-Xis, having stolen the mysterious Andromeda Key from the FM King, claims to have knowledge of the boy's missing parent. The two are able to merge becoming Star Force Mega Man, in the Japanese version. Geo uses this newfound power to protect his friends and others from the invading FM-ians. Aided by Sonia Strumm and Lyra, they combat such threats as the forces of the FMian king, Cepheus, as well as the minions of Dr. Vega and the Dealers of Mr. King. Sonia and Luna have been shown to have feelings for him, though he is seen to be oblivious. Like any 10-year-old, however, any mentioning of either not only leaves him confused, but embarrassed as well. In third game, he is officially allied with the Satella Police and is registered under Project TC—a registry of those allowed to legally perform Wave Change—as No. 003. In the manga, Geo's back-story remains the same. However, he is more ambitious about building up the strength to find his father. Geo goes after the "Star Force," a power being offered to the winner of the Wave Coliseum, a tournament pitting various radio wave humans against each other in battle. Also, as the manga is aimed at a younger audience, Omega-Xis is a lot more comical.
Omega-Xis, known as in the Japanese version, is an AM-ian and survivor of the Planet AM's annihilation; unlike FM-ians, AM-ians are able to turn humans into EM waves without fusing with them. At first, Omega has no feelings towards the Earth or its people, including Geo, with his only concern being the safety of the Andromeda Key; however, he slowly begins to change and care for Geo and the others.
Geo and Omega-Xis, in their Mega Man form, appear in Super Smash Bros. for Nintendo 3DS, Super Smash Bros. for Wii U, and Super Smash Bros. Ultimate as part of Mega Man's Final Smash called Mega Legends alongside MegaMan.EXE from MegaMan NT Warrior, Mega Man X, Mega Man Volnutt from Mega Man Legends, Proto Man, and Bass.
Sonia Strumm and Lyra Sonia Strumm Lyra
Sonia Strumm, known as in the original version and Sonia Sky in the dubbed anime version, is a popular rock star who, like Geo, is also depressed over the loss of a parent, her mother, which leads them to establish a friendship. She is similar to Mayl Sakurai in the Battle Network series. In terms of demeanor, Sonia is quite the opposite of Geo: spunky, outspoken, and mischievous. Sonia seems to be romantically interested in Geo, shown by the fact that she has asked Geo out on dates several times. Sonia also throws herself in front of one of Queen Ophiuca's attacks to protect Geo, and as a result is poisoned. In the second game, Sonia again asks Geo to go a date to Wilshire Hills. In this game, Sonia seems more blatant about their relationship. She once asked Geo who he likes better between an argument with Luna. She has also shown jealousy when Geo is with a girl or Luna alone during his mission of finding the OOPArts. Sonia is constantly pressured by her money-starved manager, leading Lyra to manipulate her into transforming into Harp Note, Lyra Note in the English anime, and attack people throughout the city. In the second game, Hollow blackmails her into working for Vega in exchange for Geo's safety. When Mega Man finds her in the Bermuda Maze, she claims that she doesn't want to be found and cuts off their Brother Band. Later, when Mega Man is lured out by Hollow and Rogue, Harp Note rescues him and transports him back to Echo Ridge. When Mega Man goes back to the Bermuda Maze, he defeats Harp Note. There, she explains she was following Vega's orders to protect to which Geo replies how her betrayal did not protect him. She also helps Mega Man find Mu's location in the Bermuda Maze afterwards. In the third game, Sonia is officially allied with the Satella Police and is registered under Project TC—a registry of those who are allowed to legally perform Wave Change—as No. 004. She also is an actress and appears on a TV drama. Notably, all of the songs sung during the anime are sung by Misato Fukuen, and twice, once during the anime and once during the games, Misora Hibiki is portrayed actually singing the theme songs, the latter case done through printed vocals.
