==Biography==
===Kingdom Hearts Birth by Sleep===
Terra meets a young Sora and Riku on Destiny Islands, and chooses the latter as his successor to wield the Keyblade. They later meet Aqua, who finds that the friendship between them is similar to the one between her, Terra and Ventus. Sometime after that, Sora and Riku are resting on the beach. When they are about to head home, Riku sees Sora shed a tear, and thinks that someone from another world (Ventus) is sad and recommends that Sora try to reach out to him.
===Kingdom Hearts===
Now 15 years old, Riku desires to leave the islands with Kairi and Sora on a raft and see other worlds. The night before they were to depart, after building the raft and gathering supplies like food, Riku's curiosity got the better of him and he opened up the door in the secret place which lead to the Heartless attacking his world. He is later found by Sora on the island with the paopu tree, indifferent to the Heartless invasion and desires to take advantage of them to see other worlds and opens his heart to darkness and attempts to take Sora with him. Unknown to Riku, at this critical moment, the Keyblade Terra promised Riku arrives, but due to Riku have given in to the darkness, it deemed him unworthy and so chose Sora as its wielder, saving him from being pulled into the darkness.
Riku awakens on the world known as Hollow Bastian and is found by Maleficent, who offers him shelter and protection and he gains the darkness-wielding sword Soul Eater. Maleficent offers to help him find his friends if he helps her find the remaining Princesses of Heart and begins to manipulate him to her side. Riku finally comes across Sora in Traverse Town, though finds that he has new friends in Donald and Goofy as well as gaining a Keyblade, which he silently recognizes as the one meant for him and suddenly leaves when the three aren't looking. Meeting with Maleficent, she turns him against Sora by telling him that his friend has simply replaced him and Kairi with Donald and Goofy, though he remains suspicious of her motives.
Regardless, he joins her in her schemes, kidnaps Jasmine from Agrabah and takes her to Hollow Bastian, and in exchange, Maleficent reveals Kairi's location, the world of Neverland, though she has lost her heart. Seeking a way to save Kairi's heart, Riku enters the whale Monstro to get to the puppet Pinocchio but finds Sora is there also, and while they work together to save Pinocchio from a Heartless, Riku kidnaps the puppet afterwards and asks Sora to join him in saving Kairi, but Sora refuses as he knows Riku is in the wrong. When the Heartless returns, Riku abandons Pinocchio and flees. 
Maleficent bestows Riku with the powers of darkness and gives him the ability to control the Heartless before he sets out with Captain Hook to Neverland to retrieve Kairi, though finds Sora has caught up to him again. He creates a Heartless duplicate of Sora and traps him below deck. After informing Hook that Wendy isn't a Princess of Heart, he uses the power of darkness to transport him and Kairi back to Hollow Bastion and Maleficent unlocks further darkness in his heart.
Riku confronts Beast in the outskirts of Hollow Bastion, mocking him for trying to save Belle before wounding him, but is stopped from finishing him by Sora. Riku reveals he has been waiting for Sora and uses the strength his heart has gained from darkness to take the Keyblade from Sora and reveals himself as the true chosen one of the Keyblade, writing Sora off as a delivery boy and leaves him with an old toy sword to make do with before leaving with Donald and Goofy who, as per their king's order, must follow the key.
As a result of his heightened darkness, Riku takes on a new form by the time Sora catches up with him in the entrance of the castle, after Beast is lured away by an illusion of Belle becoming a Heartless, enraging him to attack the Heartless in a blind fury, and when Sora refuses to leave without Kairi, Riku attacks him, but Donald and Goofy rise to his defense. This causes Sora to realize his real strength wasn't the Keyblade, but his friends he has made over his journey and he doesn't need the Keyblade to keep fighting. The realization makes Sora's heart stronger than Riku's darkness and the Keyblade completely abandons him and fully accepts Sora, to Riku's disbelief and shock, forcing him to attack with Soul Eater, but is overpowered. Defeated, Riku flees and is confused and outraged over how his Keyblade could abandon him. That is when a figure appears to him, promising to make him stronger if he plunges into the darkness and possesses him when he does so. As a result, Riku gains a new Keyblade made of the hearts of six of the Princesses.
Rejoining Maleficent, he warns her of the dangers of the darkness and after she is defeated by darkness, he reveals his Keyblade has the power to unlock a person's heart and forcefully does so to Maleficent, turning her into her dragon form. Sora catches up with the possessed Riku in the Keyhole room and its revealed Riku is possessed by Ansem, the Seeker of Darkness, and that not only is Kairi a Princess of Heart, but her heart is within Sora's and it must be retrieved if she is to awaken and complete the Keyhole. After his defeat, he fades away, but as intended, Sora unlocks his heart with his discarded Keyblade, which awakens Kairi and finishes the Keyhole. Ansem then modifies Riku's form to resemble his and sends the Heartless after them, but Riku holds him back long enough for the others to escape. To prevent further actions in the future, Ansem banishes Riku's heart out of his body and into the Realm of Darkness. 
After Ansem is defeated, Riku regains his body and helps Sora close the door of Ansem's Kingdom Hearts. Due to not being of the Realm of Darkness, Riku is unable to cross the door back to the Realm of Light and so works to help Sora close it at the sacrifice of being trapped in the Realm of Darkness, and as a final favor, asks Sora to look after Kairi before the door closes.
===Chain of Memories===
Riku traveled throughout the basement area of Castle Oblivion. During Marluxia's attempted coup against Organization XIII, while Sora fought against Marluxia's traitor faction, Riku fought against Zexion's group of loyalists. He would also battle the Riku Replica a number of times. He later meets The King and DiZ. He finally defeated Ansem, whose shadow still lingered in his heart after his defeat in Kingdom Hearts, and began his quest to control his darkness and help Sora awaken.
===358/2 Days===
Riku teams up with DiZ to help Sora awaken. He defeats Xion and calls her Keyblade a sham. He has Xion decide what to do. DiZ eventually gets fed up with the delays, and has Riku capture Roxas. Riku faces Roxas in the Dark City of The World That Never Was, where after fending off an army of Neoshadow Heartless, Roxas and Riku face each other. At one point, Roxas gets the advantage over Riku and, upon hearing Xion pleading with him, Riku summons his own inner darkness, allowing him to summon Ansem's Guardian Heartless, who easily subdues and incapacitates Roxas, but causes Riku to take on Ansem's appearance from then on. Taking Roxas back to the Old Mansion in Twilight Town and returning to DiZ, Riku watches as DiZ sends Roxas to the Simulated Twilight Town, and waits for Sora to awaken.
===Kingdom Hearts II===
Riku keeps track of Roxas, Sora, and the Nobodies in the Simulated Twilight Town in his Ansem form. As he does, he removes from the Simulated Twilight Town any items that may prove risky to Roxas discovering the truth too soon, such as the Simulated Olette's munny pouch and the blue crystal from the Struggle trophy Roxas won. However, during a private meeting with DiZ, Riku learns that DiZ seeks revenge on Organization XIII. Unwilling to aid DiZ in his vendetta against Organization XIII, Riku hands the items he took from the Simulated Twilight Town to King Mickey to give to Sora after he awakens. He meets the Emperor and battles Sora in the Land of Dragons, taking time to warn the Emperor of Organization XIII member Xigbar's plans to summon the Stormrider Heartless to attack the Imperial City and Palace with. He later assists Naminé and Kairi with escaping from The Castle That Never Was when they are intercepted by Saix and two of his Berserker Nobodies, where Kairi recognizes him, despite his Ansem appearance. He also grants Kairi her Destiny's Embrace Keyblade to fight the Heartless with. He soon reunites with Sora, and after they defeat Luxord and Saix, Riku explains the truth about Roxas to Sora. He becomes his old form again after DiZ's encoding machine explodes while trying to encode Xemnas' Kingdom Hearts, and works with Sora, Donald, and Goofy to defeat Xemnas and return home with his friends.
===Kingdom Hearts coded===
When Jiminy's Journal is digitized, a data version of Riku is created to act as a vessel for the memories in it. In the ending cutscene, Sora and the real Riku are on Destiny Islands talking about how small their homeworld is, and then about the Door to Light. Kairi then arrives and gives them a letter sent to them by Mickey, and they read it together.
===Blank Points===
After reading the letter, Riku asks him if he's decided whether to go and search for the people connected to him. He replies that he has, which makes Riku smile.
===Kingdom Hearts 3D: Dream Drop Distance===
Sora and Riku are made by Yen Sid to undertake the Mark of Mastery exam to prepare them for the impending return of Master Xehanort. For their test, they are sent to the Sleeping Worlds, worlds formerly consumed by darkness that haven't yet awakened after their restoration, which they are supposed to wake up. On his journey, Riku encounters Ansem, Seeker of Darkness and a mysterious young man with ties to Master Xehanort several times, and they try to make him succumb to the darkness.
Once all the Sleeping Keyholes are sealed, Sora becomes trapped in a state of sleep in The World That Never Was. Riku comes to save him, and finds him comatose due to his heart having been damaged by Xemnas and the mysterious young man, who is revealed to be a younger version of Xehanort from another timeline. Riku defeats the Anti Black Coat in Sora's nightmare, continues to progress through the castle, and eventually encounters Ansem, who tells him that he is a Dream Eater. Riku defeats him and then finds Sora in Where Nothing Gathers, about to be made a vessel for Xehanort's heart.
Riku is able to save Sora with the help of Lea, but he still remains comatose and is brought by Riku to Yen Sid's Tower, where he enter Sora's body so he can repair his shattered heart. Inside, he has to fight the Armored Ventus Nightmare, which is Sora trapped inside Ventus's Nightmare-possessed Keyblade Armor. After defeating it, Riku goes deeper into Sora's heart and enters a memory of Destiny Islands, where he meets illusions of Roxas, Xion and Ventus, who each ask him a question. After he answers all three of them, he comes across a bottle and meets another illusion, this time of Ansem the Wise. The illusion tells him that he hid hid his research data inside Sora before he fell asleep, and that defeating the Nightmare and answering the other illusions' questions has awakened Sora. He then returns to the real world, reunites with everyone, and is named a Keyblade Master by Yen Sid. He and the others are shocked when Lea tells them that he plans to become a Keyblade Master too and summons his own Keyblade by accident.
Yen Sid then gives Riku his first duty as a Keyblade Master; to bring Kairi to him so she can receive training in using her Keyblade so that she can join in the battle against the Real Organization XIII.
===Kingdom Hearts Birth By Sleep 0.2 -A Fragmentary passage-===
After Riku brings Kairi to Yen Sid's Tower, he listens as Yen Sid tells them of his plan for protecting the other six Princesses of Heart and for saving Terra, Ventus and Aqua. Mickey reveals that he and Aqua were together when the Door to Darkness was closed, but she stayed in the Realm of Darkness to stop Riku from being attacked by a swarm of Heartless. Riku asks him why he kept it a secret until now, but Yen Sid reveals that he forbade Mickey from telling telling anyone because he was afraid that Sora would make a reckless attempt at rescuing Aqua, but that both he and Riku are now strong enough to do so successfully. When Kairi is apprehensive about her training with Lea (because of he's the human form of Axel, who kidnapped her before), Riku and Mickey assure her of his trustworthiness, telling her that he saved Sora before. Yen Sid then gives Riku and Mickey new clothes made by Flora, Fauna and Merryweather, which are meant to protect from the darkness in the dark realm, and set out on their way to save Aqua.
===Kingdom Hearts III===
Working with King Mickey, Riku returned to the Realm of Darkness to search for Aqua, but during their battles with the Heartless, his Way to the Dawn Keyblade was broken, forcing him to discard it. After being given a new one, Riku and King Mickey return to the Realm of Darkness to resume the search, but are soon attacked by Demon Tower, which captured Mickey and disarms him of his Keyblade. From the Demon Tower, a figure surrounded in an aura of darkness emerges and picks up Mickey's Keyblade. When it speaks, Mickey recognizes the female voice, before the aura dissipates to reveal Aqua, having succumbed to the darkness and been transformed into Anti-Aqua, with her voice dripping with hatred, bitterness, anger, and malice against Mickey for how long she's been trapped in the Realm of Darkness. While Mickey shows no resistance against her accusations and tries to apologize, Anti-Aqua continues to monologue, which causes Riku to have a sense of similarity to his own fall to darkness when he let himself be possessed by Ansem, Seeker of Darkness. Once Anti-Aqua decides to fight them to give them a taste of the misery and despair she now was consumed by, Riku goes on the attack himself, trying to fight the Demon Tower to rescue Mickey while avoiding Anti-Aqua as she attacks to defend her Heartless ally. Soon enough, Sora, having found Master Eraqus' Keyblade on the Destiny Islands and used it to open a door to the Dark Margin, arrives to aid Riku and help him destroy the Demon Tower and rescue Mickey. Unimpressed and unconcerned for her ally's demise, Anti-Aqua goes on the attack and lunges for Riku, but is stopped by Sora, who realizes he'll have to fight her to break the hold of darkness on her. After a difficult fight, Sora manages to cripple Anti-Aqua enough that the darkness can't maintain its hold on her and is forced to release her, turning her back into Aqua, but refusing to give her up that easily, the darkness pools under her and drags her into the water to drown, but Sora dives after her and rescues her. Aqua awakens back on the Destiny Islands where Sora and Riku reveal she's back in the Realm of Light at long last, much to her joy.
Following after Sora joins Aqua in returning to Castle Oblivion to restore it into the Land of Departure and awaken Ventus, Riku joins everyone in the Keyblade Graveyard to face Master Xehanort and his thirteen pieces of darkness. However, Terra-Xehanort ambushes them and takes out Ventus and Axel before being repulsed by Donald's Zettaflare, which exhausts Donald due to the amount of magic and strength he put into it, leaving everyone at the mercy of a massive Demon Tide tornado. Though Riku, Sora, and Aqua attempt to face it together, Aqua hesitates, paralyzed with fear as she sees the Shadows inside as Anti-Aqua, fearing she would become her dark self again, allowing the Demon Tide to sweep up her, Ventus, Mickey, Donald, Goofy, Axel, and Kairi. Unable to save Kairi, Sora becomes despondent, fearing they've lost already, but Riku heroically makes a desperate last stand to protect Sora from the Demon Tide before it consumes him and goes for Sora next. For a moment, it looks as if the prophecy of the Keyblade War has come to pass as light expires and darkness wins.
However, Kairi's light as a Princess of Heart allows Sora to survive in the Final World, giving him a chance to restore his body and use his power of waking to rescue everyone before their hearts are cast into oblivion by the Lich, the Heartless Grim Reaper, killing them permanently. Riku's lifeless, translucent body is found on Mount Olympus, just as the Lich manifests to draw out his heart, enwrap it in chains, and claim it before taking its leave. Sora pursues it and manages to confront it and attack it until it is forced to let Riku's heart go, the chains encasing it shattering, leaving it to float into the sky and disappear. Jiminy Cricket assures Sora that Riku's heart is heading back to the Keyblade Graveyard to restore his body to flesh and blood and revive him from his near-death state, and it will be the same for everyone else once Sora rescues their hearts from the Lich. Pursuing the Lich, Sora rescues Aqua, Ventus, Donald, Goofy, King Mickey, and Axel from meeting similar fates in the other worlds, but not without being forewarned by Young Xehanort of the price he will pay for misusing his power of waking like he is to undo the events of the Keyblade Graveyard and violating the Master of Masters' prophecy in the process. Despite the warning, Sora soon reunites with Kairi, having managed to keep her heart and body alive despite what happened to everyone else, and they return to the Keyblade Graveyard together, returning mere moments before the encounter with Terra-Xehanort, with everyone restored alive and well, and ready to try again to take down Master Xehanort.
When they encounter Terra-Xehanort a second time, before history can repeat itself, the Lingering Will, Terra's Keyblade Armor possessed by his willpower, arrives to chase Terra-Xehanort off the scene, before the Demon Tide tornado once more makes itself known, but aided by the Keyblades of fallen Keyblade Warriors from around the graveyard, Sora destroys the Demon Tide tornado once and for all. His endgame having failed, Master Xehanort creates the Skein of Severance labyrinth for the Guardians of Light to face off with his thirteen darkness to bring his plans to fruition. After Master Yen Sid personally arrives to hold off the army of Heartless, Nobodies, and Unversed with Donald and Goofy so the Guardians can go after Xehanort, Riku and King Mickey fight their way to Master Xehanort, and are soon joined by Sora as they face Master Xehanort's last three defenders in Ansem, Seeker of Darkness, Young Xehanort, and Xemnas. Once they are defeated, Master Xehanort brings out an unconscious Kairi, whom Xemnas captured earlier while Sora was aiding her and Axel against Saix and Xion before Xion took over her Replica's body as her own and Roxas arrived to assist his old friends, giving Xemnas the opening to grab Kairi. Telling Sora he needs motivation to help him rebuild the X-blade, Master Xehanort cruelly cuts down Kairi in cold blood, infuriating Sora, Riku, and King Mickey, but their attempts to attack Master Xehanort are easily repulsed as Master Xehanort deflects Sora and Riku's strikes, then uses Stopza to evade Mickey's Ultima attack.
With the X-blade reformed, Master Xehanort summons Kingdom Hearts and prepares to unleash his true endgame. Sora decides to face him alone, aided by Donald and Goofy, and the other Guardians of Light use their Keyblades to turn Master Xehanort's power of time against him, allowing Sora, Donald, and Goofy to take Master Xehanort into Kingdom Hearts and fight him in his old home of Scala ad Caelum. By the time Riku and the others arrive, Master Xehanort is defeated, but remains adamant to carry out his plans, despite his deteriorating condition. When Master Eraqus' spirit then appears from Terra and tells Xehanort it is over, declaring checkmate to their chess game they played when they were younger, Xehanort finally accepts defeat, entrusts the X-blade to Sora, and passes peacefully into the afterlife with Eraqus. Using the X-blade and supported by Riku and the others, Sora seals Kingdom Hearts for good. Afterwards, back in the Keyblade Graveyard, as Sora prepares to track down Kairi, despite the dangers of using his power of waking again to help her, Riku gives him his full support and wishes him good luck.
Some time later, Riku returns to Radiant Garden in a Gummi Ship to pick up Naminé, who had just been given a new body thanks to Ansem the Wise and his assistants, and takes her to join everyone else on the Destiny Islands to celebrate. Soon, everyone's attention is drawn to Sora and Kairi sitting on the paopu tree, as Sora spends one last moment with her after saving her before he vanishes to parts unknown as punishment for misusing his power of waking and defying the Master of Masters' prophecy of the Keyblade War written in the Book of Prophecies.
=== Kingdom Hearts: Melody of Memory ===
Hoping to track Sora down and rescue him, Riku begins the search via his dreams with the Fairy Godmother's help, and after paying a visit to the Final World with Kairi thanks to the Fairy Godmother to speak with the Nameless Star that Sora had befriended during his short time there, Riku learns that Sora is in Quadratum. With the Nameless Star's help, as she was from that realm, Riku departs to Quadratum to recover Sora while Kairi and the other Keyblade warriors remain with Yen Sid so Kairi can continue her training under Aqua while Mickey searches Scala ad Caelum for clues about Kingdom Hearts.
==Abilities==
===Swordsmanship===
Riku is a self-taught swordsman. He learned to fight with a sword as a child and was the strongest among his friends on Destiny Islands. 
===Magic===
As a keyblade wielder, Riku can use magic, but he is unique in being able to control both darkness and light. Having trained to control the darkness within him for a year, Riku can manipulate it into projectiles and make it burn like fire rather than tax his heart by cloaking himself with it for his Dark Mode suit. 
==Quotes==
==Trivia==
