# Ryu Hayabusa

Ryu Hayabusa (Japanese: リュウ・ハヤブサ/隼 龍, Hepburn: Hayabusa Ryū) is a fictional character and the protagonist of Tecmo and Koei Tecmo's Ninja Gaiden action-adventure video game series. He is a human-dragon hybrid who wields an ancestral weapon called the Dragon Sword, and is the leader of the Hayabusa Ninja Clan. One of Tecmo's most enduring characters, Ryu has also appeared as a player character in the Dead or Alive fighting game franchise by Koei Tecmo and Team Ninja where he serves as the protagonist in Dead or Alive 2. Ryu is featured on official series merchandise as well as in the feature film DOA: Dead or Alive, and has made many crossover appearances in other games.
He has received favorable reception from critics and audiences, and is considered to be one of the most iconic examples of a ninja character in video games as handful of critics have ranked him as one of the most iconic ninjas in gaming.

## Conception and design

Ryu Hayabusa is equipped with a katana-like Dragon Sword, shurikens, and ninpo techniques such as fire wheels. In designing the protagonist Ryu Hayabusa, the development team wanted him to be unique from other ninjas. They designed him with a ninja vest to place emphasis on his muscles, and they furnished him with a cowl that arched outward. They originally wanted to equip Ryu with sensors and a helmet with an inside monitor to check his surroundings, but that idea was scrapped. According to Kato, they used specific locations and environments to justify the need for having a ninja for a main character.
When asked in 2008 if he would ever explore a "stealth aspect" of Ryu in a future series title, Ninja Gaiden: Dragon Sword designer Tomonobu Itagaki replied, "The kind [of ninja] I like are the ones that go out and kill a bunch of enemies all at once." The Nintendo DS-exclusive game was played by holding the console vertically; Itagaki explained, "We have implemented an immensely intuitive control system. If you use the stylus to slice side-to-side over an enemy, Hayabusa will slash him with his sword, and you can change the type of slash by varying the angle of your slice."
Starting with Ninja Gaiden II, the series' graphic violence greatly increases as Ryu is able to defeat opponents by decapitation or dismemberment. In a 2011 interview with PlayStation.blog, Team Ninja head Yosuke Hayashi described the character's development in Ninja Gaiden 3: "The human side of Ryu Hayabusa comes through ... you see him suffering as a consequence of the murders he has committed and that is when [his] humanity comes through. I believe that, these days, people are looking for more realistic games and that’s not easy to do with Ninja Gaiden, which is heavily based in fantasy." He commented on the gameplay itself, "Within the course of the story, you will ... have a harder time progressing through stages, [but] we have to have the players feel like Ryu is a superhero, the Ryu Hayabusa they know, to make them emphasize with the consequences ... as the game progresses."
Team Ninja wrote that his signature move in Dead or Alive 5 was the "Izuna Drop—a powerful throw that he can perform even from strikes or holds." According to Prima Games' official guide for Dead or Alive Ultimate, Ryu is "fairly fast and has decent power, though he doesn't necessarily excel at either, making him a fairly well-balanced character," adding that he can be useful to a moderate-level player in certain situations. The publisher said for Dead or Alive 4 that he "continues to be one of the top characters in the Dead or Alive series" and can still be played at top levels; he was rated seven out of ten overall. According to GameSpot, Ryu's attacks in DOA4 "are difficult, [but] the bulk of them are actually fairly easy to pull off, and he's quite fast to boot, making him an excellent choice of character for new players."
During Tecmo's development of the first Dead or Alive fighting game, lead developer Tomonobu Itagaki initially planned to include a male ninja named "Kamui". Another developer proposed they include Ryu instead as it was already a developed character under Tecmo's corporate banner, and Itagaki received permission to include the character from the company's then-CEO. Itagaki however was unfamiliar with what sort of character Ryu was, and in an interview with Famitsu explained to learn more about the character he located and assembled a Ninja Gaiden arcade cabinet from the company's warehouse to play. To illustrate a distinction between Dead or Alive and Ninja Gaiden, the former's development team chose to refer to the character as "Hayabusa" within the games themselves, in contrast to how he is referred to by his first name more in the latter. As later Ninja Gaiden games were released, his outfit from those games was included to better tie the franchises together.
While the development team wanted to add gymnastic attacks to the character in Dead or Alive, the development process made that too difficult at the time, so Itagaki added moves such as a throat cut against opponents to try and "bring out the image of Hayabusa". Additionally he envisioned Ryu as a grappling-type character that used throws, but did not want him to feel too similar to the wrestling move-based character Tina Armstrong. To achieve this he limited the character's throwing attacks so Ryu would feel distinct from the "grappler" archetype in fighting games. Later games in the series focused on his hand motions to help design strikes that felt suited for the characters. Some attacks such as a handstand were removed from later titles as they felt inconsistent with character's portrayal in Ninja Gaiden.

## Appearances
### Ninja Gaiden series (1988-1992)

Ryu Hayabusa makes his official debut in the original Ninja Gaiden arcade game released in 1988. In the Nintendo Entertainment System home edition released the same year, taking place in the retro-futuristic version of 1988, he is given a backstory of searching for his missing father who had disappeared to partake in a life-or-death fight. Ken had instructed Ryu in a letter beforehand to travel to the United States to find his friend Dr. Walter Smith, but Ryu encounters Bloody Malth, who had defeated Ken in battle and then subjected him to a brainwashing that causes him to attack his own son, a spell that Ryu manages to break. However, Ken is slain by Malth's superior, an evil sorcerer known as the Jaquio, whom Ryu then kills. Ryu later enters into a relationship with CIA agent Irene Lew, who had refused beforehand to carry out an order to terminate him.
In Ninja Gaiden II: The Dark Sword of Chaos (1990), Ryu foils the Jaquio's demonic master Ashtar's attempt at world domination. In retaliation, Ashtar kidnaps Irene in order to lure Ryu to his home dimension. Ryu defeats Ashtar a second time, but before he can rescue Irene, she is then captured by the Jaquio, who now bears the Dark Sword, the antithesis to Ryu's signature "Dragon Sword" weapon. Having then been killed by Ryu once again, the Jaquio is revived by his blood flowing into his sword, with which he stabs Irene. Her own blood further empowers his sword and conjures a creature known as the Demon; Ryu kills it and Jaquio's Dark Sword is destroyed in the process, but Irene dies from her wounds. She is then brought back to life by ancestral powers flowing through Ryu's Dragon Sword.
1991's Ninja Gaiden III: The Ancient Ship of Doom sees Ryu accused of murdering Irene, but she actually survives the attack, while the culprit is revealed to be a superhuman clone of Ryu called a "Bio-Noid", created by Irene's superior and corrupt CIA director, Foster. After Ryu defeats the double, Foster is killed by H.P. Clancy, who had instructed Ryu to locate a ruin called the "Castle Rock Fortress", which was the base of Foster's Bio-Noid experimentation and has also secretly housed an interdimensional warship that Clancy intends to use for global dominance. Ryu kills Clancy in battle and the ship is destroyed as Ryu escapes with Irene, bringing the first-generation Ninja Gaiden storyline to a close.
The 1991 Sega Game Gear version of Ninja Gaiden scraps the entire narrative of the original series timeline, where someone is trying to steal his dragon sword. He travels to four parts of the world to defeat the demon Shiragane and prevent World War III from starting.
The 1992 Sega Master System version of Ninja Gaiden also eludes the original series timeline, featuring Ryu as a high-ranking member of his ninja clan whose village is massacred while an artifact called the "Sacred Scroll of Bushido" has been stolen. His mission is to regain the scroll from the hands of the evil Shogun of Darkness and his minions.

### Ninja Gaiden series (2004-2025)

In Ninja Gaiden (2004), the first release in the second generation of the Ninja Gaiden series, the plot precedes Ryu's acquisition of the Dragon Sword, though it contains story elements similar to the Master System port of the original game in that while Ryu is visiting his uncle Murai, Hayabusa Village is annihilated in his absence and a sword known as the "Dark Dragon Blade" is stolen by the evil Doku, whom Ryu vainly tries to stop before he is slain in his attempt. He is brought back to life by his clan's animal spirit, the falcon, and he searches for the stolen sword while hoping to avenge his clan. He defeats Doku and then his overlord, the Holy Emperor Vigoor, and recovers the blade. In the end, Ryu and his newest accomplice, a fiend-hunter named Rachel, encounter the mysterious "Dark Disciple", who is actually Ryu's traitorous uncle. After Murai's death, Ryu destroys the sword.
The plot of 2008's Ninja Gaiden: Dragon Sword begins with kunoichi Momiji abducted by the rival Black Spider ninja clan. Ryu's objective therein is to find seven Dark Dragonstones, defeating several bosses along the way. At the climax, Doku's former servant Ishtaros steals the stones and defeats Ryu in battle. However, when Kureha—Momiji's sister and a childhood friend of Ryu from the previous game who had died in the village attack—fuses with an object called the Dragon Eye, the stones transform into the Dragon Sword. Ryu defeats Ishtaros and her sister (who takes the shape of a dragon during battle), then frees Momiji and returns her home where they begin training together.
In Ninja Gaiden II (2008), set six months after the events of Dragon Sword, a CIA agent named Sonia warns Ryu of a plot of the Greater Fiends, whose queen, Elizébet, attempts to steal an artifact called the Demon Statue, which is hidden in the Hayabusa ninja village and what she desires in order to resurrect the Archfiend Vazdah, the game's final boss. After his village is razed once again and the statue is stolen, Ryu infiltrates a castle where the object is held. Joe is critically wounded in his battle against Black Spider clan leader Genshin, who then attempts multiple times to kill Ryu thereafter but fails and is slain in his final attempt despite Elizébet having transformed him into one of the game's sub-bosses, the Four Greater Fiends. Before he dies, Genshin gives Ryu a sword called the "Blade of the Archfiend", which Ryu needs to complete his mission. Following the demise of the three other Greater Fiends, Ryu kills Elizébet and Vazdah with both the blade and his own Dragon Sword. At the conclusion, he uses the Archfiend's sword to mark Genshin's gravesite in a cemetery located at the summit of Mount Fuji.
Ryu is summoned by the JSDF in Ninja Gaiden 3 (2012) to assist with the suppression of a terrorist group called the Lords of Alchemy. He pursues the terrorists and their mysterious leader around the world, but realizes he cannot complete his mission without the Dragon Sword. While stalking the group, he also must save a young girl whom he had promised to protect, named Canna. After he succeeds in terminating the group, he destroys another final boss character bent on global destruction and returns the child safely to her mother before disappearing into the shadows. Ryu's story continues in the 2013 release Yaiba: Ninja Gaiden Z, in which he is not playable; instead, he is pursued by the game's "foul-mouthed" protagonist, Yaiba Kamikaze, in his quest for revenge after having been wounded by Ryu's Dragon Sword.
In Ninja Gaiden 4, the veteran Ryu Hayabusa serves as a "major challenge and growth milestone" for the protagonist Yakumo, while also being playable throughout the story (ignoring the events of Yaiba: Ninja Gaiden Z), utilizing similar moveset and tools to his earlier appearances.

### Dead or Alive series

Ryu is additionally a player character in the Dead or Alive games, which take place chronologically years after the Ninja Gaiden series. He is written into the events of each of the Dead or Alive fighting tournaments, starting with the 1996 original game, in which he receives an invitation to the inaugural Dead or Alive tournament which he participates in while searching for fellow ninja, Kasumi, after she broke shinobi code and ran away from her village to get revenge on Raidou who crippled her brother, Hayate. After Raidou's defeat at Kasumi's hands with little aid from Ryu, Kasumi was kidnapped, leaving Ryu and Ayane to search for her. Ryu is the primary protagonist in the 1999 sequel Dead or Alive 2 where he canonically wins the second championship upon learning beforehand that an interdimensional creature named Gohyakumine Bankotsubo, escaped the Tengu world and joined the tournament to wreak chaos on the human world. Ryu with the help from Irene, rescues Kasumi from the Dead or Alive Tournament Executive Committee's (DOATEC) Germany facility, where she was being used as a test subject for the organization's Super Human Development project. Ryu later comes across his lost friend Hayate, now an amnesiac calling himself "Ein", who was also previously kidnapped and unwillingly use as a test subject in DOATEC's Epsilon project. His defeat at Ryu's hands restores parts of his memory. Ryu then destroys Tengu to save the world from his would-be plot, winning the second tournament. He later helps Hayate to fully recover his memories by fighting his own sister Kasumi, then found out together that Genra, Ayane’s foster father became a traitor like Raidou was, such as joining Victor Donovan’s DOATEC anti-Douglas faction, explaining the company’s faction involvement on kidnapping and cloning Kasumi for their Alpha clone project and implanting Hayate with “Epsilon”.
His role in Dead or Alive 3 (2001) is more minor, as he faces off against Hayate, who has become the newest leader of the Mugen Tenshin ninja clan, as well as aiding both Hayate and Ayane against the Omega empowered Genra. In Dead or Alive 4 (2005), Ryu joins fellow clansmen Hayate, Ayane, Kasumi, and other members of the Mugen Tenshin clan to stop the corruption within DOATEC by assaulting and detonating their "Tritower" headquarters. Victor Donovan's hired assassin Christie attempts to stop them, until she is distracted by Helena Douglas, allowing the ninjas to succeed in destroying the building. Ryu returns in 2012's Dead or Alive 5 which chronologically takes place two years after Dead or Alive 4 and Ninja Gaiden 3. Ryu aids Hayate and Ayane in their battle against Donovan's new organization, MIST, who plans to sell modified soldiers to various militia around the world. When Hayate is captured, Ryu sends his falcon to send a message to Kasumi in order to summon her to battle. When she frees Hayate, the four of them destroy the MIST laboratory. As Ryu sense the resurrection of Raidou set up by MIST is approaching in Dead or Alive 6, Ryu warns Kasumi about this referred threat, with MIST’s new target to resurrect Raidou as an undead cyber ninja by kidnapping both of his illegitimate daughters, Ayane, and Honoka. He was approached by the princess of the Tengu world Nyotengu, proving his might as a man who ended Bankotsubo’s crime, sparring her and tells her to leave human world, satisfying her as well. Whereas Hayate, Kasumi and Ayane goes after resurrected Raidou, and Helena goes after Raidou’s resurrector NiCO, Ryu, alongside Bayman and Marie Rose watching over Honoka recovering.
A demo version of DOA5 featuring a playable Ryu and Hitomi was included as a downloadable bonus with pre-orders of both the standard and collector's PlayStation 3 editions of Ninja Gaiden 3, as well as the Xbox 360 version.

#### Film

In the 1991 Japan-exclusive OVA film Ninja Ryūkenden, an original adventure loosely based on the early games, Ryu was voiced by Keiichi Nanba, and he was given a red and purple palette as opposed to his solid blue in the NES series, while he is unmasked. Set in New York City, the plot involves a doctor who has supposedly discovered a cure for cancer. He in turn is investigated by a reporter named Sarah, who soon discovers that he is conducting biotechnological experiments on live humans, which possibly involves the power of the Evil Gods, whom Ryu had defeated in the past. This is compounded by the abduction of Irene—the only other returning character from the games, but identified therein only as Sarah's friend—in turn forcing Ryu to become the Dragon Ninja once again and defeat this new enemy and save her. The conclusion has Ryu remaining in America, where he marries Irene and they open an antique shop together.
Ryu is briefly seen in the 2002 film Run Ronnie Run, where the character, Jerry Trellis (portrayed by E.J. De la Pena), is playing on a Dead or Alive 2 arcade cabinet.

## Reception

Since his 1988 debut, Ryu Hayabusa has been both critically and publicly received as a popular character in general video gaming when it comes Nintendo and Xbox audiences. The character was popular through how he promoted the first games with his image. Nintendo Power honored the game in its November 2010 issue. The magazine listed its box art, which depicts a ninja with a burning city in the background, as one of its favorite designs in the NES library. The magazine's Editor-in-Chief Chris Slate was equally impressed by the game's box art. IGN the character had a notable evolution ever since 8-bit generations and he always looked well designed in gameplay and cutscenes. The same site especially regarded one of the latter as one of the best cinematic scenes for starting Ryu's journey after the death of his father. Eurogamer said that Ryu Hayabusa became a more notable character thanks to the presentation of the first NES Ninja Gaiden as its cutscenes elaborated more on him like links to a father figure and villains the hero often has to fight. However, he still thought the story was the weak point of the games.
In 2010, the magazine listed Ryu as one of the best ninja characters to appear on Nintendo consoles. GameRant regarded Ryu Hayabusa as one of the best martial artists in gaming thanks to how fun is his ninjutsu to use in the video games especially with his Dragon Sword. GamesRadar found him as a brutal character despite his heroic portrayal, remaining as one of the "most memorable, influential, and badass" gaming protagonists. GamesTM enjoyed his design, seeing as one of the most athletic characters in gaming.
Despite the positive response Ryu's character received in his games, his portrayal in Ninja Gaiden 3 was the subject of criticism by Daily News for being portrayed as a passive fighter compared to his past brutal characterization with his design no longer involving his mask. The writer said Ninja Gaiden 3 features a more sensitive and vulnerable Ryu as a result of killing so many enemies in previous games. The change of personality was compared to Samus Aran from Metroid: The Other M which resulted in the protagonist receiving negative backlash for her characterization. Siliconera panned the handling of the protagonist in Ninja Gaiden 3 for being overly guilty over his actions despite spending multiple installments killing enemies, ruining the appeal of the franchise. The Gamer also panned this take of Ryu, calling it "murder hobo" and all of murders Ryu keeps committing make the plot lack any sense. In contrast, Siliconera saw the altered Ryu from the remake Razor's Edge as more violence than in the original Ninja Gaiden 3 which the writer noted to have ended on failure with one of the reasons being the protagonist's personality. Dual Shockers and GamesRadar praised how Razor's Edge no longer questions the character's moral and instead give the player freedom in regards to what Ryu can do to the enemies at the cost of removing several scenes involving such state of the protagonist.
After Soulcalibur V was released, Elton Jones of Complex wanted him as guest characters a future series entry; He enjoyed the skills of Taki and Natsu but wanted Ryu to be the focus of the story. Merchandising of the character has appealing to EndGadget for its chibi form that contrasts his signature style. Red Bull regarded Dead or Alive as one of the best crossover games ever mainly because the writer favorited Ryu Hayabusa, referring him as the best ninja in fiction, and playing as him was rewarding. Ryu's inclusion in Warrior's Orochi was praised by PlayStation Blog due to how his continuous guest appearances in several games made him an icon in Koei Tecmo.
