|~ Repliku to Sora.|
|“||I'm not Riku. I'm fake. I can't remember when I was created, or why... All I've got left is you and Naminé. But those memories aren't real...||„|
|“||I thought by finding some new strength, I could finally be someone... Someone who is not at all you! But... nothing changes... I'm still just empty! Everything about me is borrowed. As long as you're around, I'll never be more than a shadow!||„|

|“||A faithful replica until the very end. That's... okay.||„|

The Riku Replica, also known as Repliku, is a Replica of the original Riku and a major character in the Kingdom Hearts series. He first appeared as an antagonist in Kingdom Hearts: Chain of Memories and as a supporting character in Kingdom Hearts III. His past self, Dark Riku, also appears as an antagonist and member of the real Organization XIII in Kingdom Hearts 3D: Dream Drop Distance and Kingdom Hearts III.
He is voiced by David Gallagher in English and Mamoru Miyano in Japanese.
Chain of Memories
The Riku Replica was an experimental Replica made by Vexen after he studied and took interest in the original Riku. With the help of Naminé, Vexen was able to give the Replica memories to help motivate him to help them. But the Replica was ultimately defeated by Sora, and his heart was destroyed by Naminé in an attempt to calm his anger. After miraculously reviving, he expressed that despite having no memories of his own he will protect Naminé. He is growing exponentially in strength, however he still feels empty inside.
Wanting to become someone unique, Axel convinces him the only way to do this is to gain power Riku does not have. To do so, the Replica hunted down Zexion, who had just lost a fight with the real Riku, so that he could absorb his power and challenges the real Riku to one last fight in which the Replica would not hold back. After being defeated by Riku, the Replica's body was destroyed while his heart vanished into darkness, finally at peace with himself.
|“||I'd say that's our finest hour! (Riku: Wrong! My hour of weakness) You sure!? how about we find out! a real test for the Mark of Mastery. (Riku: What did you say!?)||„|

In Kingdom Hearts 3D: Dream Drop Distance, the Riku Replica's heart is collected from the past by Young Xehanort and joins the True Organization XIII as "Dark Riku". Prior to becoming a vessel for Master Xehanort's heart, Dark Riku enters the Sleeping World of Prankster's Paradise to unnerve the real Riku by recreating his kidnapping of Pinocchio. Though Riku manages to catch him, Dark Riku simply disappears into darkness, causing Riku to recall the Replica. Later, Dark Riku joins his fellow Organization members as Master Xehanort prepares to make Sora his thirteenth vessel, but is forced to retreat back to his time due to interference from Lea, Donald, and Goofy.
In Kingdom Hearts III, Dark Riku visits San Fransokyo to conduct an experiment to recreate a heart from data. Posing as the real Riku's past self, he uses the Darkubes and the original Baymax's combat chip to forge a heart using the despair and terror of the citizens alongside the optimism of Big Hero 6 and Sora's team. After gathering enough data, Dark Riku corrupts the original Baymax into Dark Baymax, but Dark Baymax is defeated and purified by Sora.
Later, Dark Riku confronts Maleficent and Pete as they are walking down a highway in San Fransokyo looking for a black box. He questions the former why she and Pete are snooping around to which Maleficent responds that is none of his concern, Dark Riku responds by stating if she oversteps, darkness will consume her again. Interested in his words but nonetheless caring very little, Maleficent states she intends to do whatever she pleases and states he should do the same. Dark Riku states he intends on doing so before walking into a portal. Pete asks Maleficent who he was and it was a friend of her's Maleficent encountering what she thinks is the real Riku's past self when he was possed by Ansem confirms this.
Meanwhile, Riku reunites with the present-day Replica's heart in the Realm of Darkness after being attacked by a Demon Tower and leaves behind his splintered Way to the Dawn Keyblade for the Replica to take. When Riku returns to the Realm of Darkness, the Replica offers his strength to fight the corrupted Aqua. At the Destiny Islands, the Replica reveals that after his destruction, his heart wandered the Realm of Darkness before Riku came along, and explains that he has unfinished business to take care of.
Dark Riku joins the Organization at the Keyblade Graveyard, encountering the Guardians of Light and shocking and enraging Riku. King Mickey believes Dark Riku to be a past version of the real Riku from the time Ansem had control of his heart. Dark Riku taunts Riku stating that was their "finest hour" but Riku states that it was his "hour of weakness", Dark Riku then summons a dark giant shadow replica of Master Xehanort telling him it was a "real test for the Mark of Mastery," enraging Riku. at that moment Xigbar appears by Dark Riku's side telling Riku not to be on the path towards a second failure and states that if they have the goods to take on the Organization they will have to prove it to Xehanort one last time, Xigbar then leaves telling Dark Riku to "take it away" which Dark Riku summons a swarm of Nobodies and Heartless for the Guardians of Light to face before disappearing.
Dark Riku later joins Xigbar and in a final clash against Sora and Riku with Ansem watching from afar. When Ansem leaves the fight Riku chases after him but Dark Riku knocks his counterpart to the ground. Upon his defeat, Dark Riku insists that he's the real Riku, much to Riku's confusion. The Riku Replica emerges from Riku, identifies Dark Riku as his past self, and expels Dark Riku's heart from the vessel. Despite Riku insisting the replica can take the vessel for himself, the Riku Replica sacrifices himself to send Dark Riku's heart back to the past and leave his vessel for Naminé before fading away, wishing his counterpart good luck. Later, Demyx retrieves Dark Riku's empty vessel, and Sora, Kairi, Ansem the Wise, Even and Ienzo use it to revive Naminé.
|“||Surprised? I guess you would be. After all, I look just like you. I bet it's not every day you meet your twin. Too shocked to speak? This should come as a relief, then: I'm a replica of you that Vexen made I didn't say "fake"! Just because you're real doesn't mean you're better! We share the same body and the same talents. There is one easy way to tell us apart, though. Unlike you, I'm not afraid of anything.||„|
|~ Repliku meeting Riku for the first time.|
|“||Unlike a certain wizard you know, I had to play by the rules to travel through time. Which meant leaving my body behind. Xehanort's heart left his body in order to voyage back through time. He needed to tell his younger self of the great plans he had in store. There in the past, his heart stayed, and waited out the years until you and I came along. Xehanort's heart possessed me and became Ansem, the first adversary you faced. The rest of him, the piece he left behind, took the name Xemnas and created the first Organization. It was all a part of a larger plan to bring Xehanort into contact with the right hearts—enough of them to form the real Organization XIII. They could come from anywhere, any when...just as long as he had the right vessels at hand to place their hearts in.||„|

- The term "Repliku" is the Riku Replica's official name in the German version of the game, and was adopted as a fan nickname for him in the English-speaking fandom.
- Among the thirteen real Organization members who died, Dark Riku is the only one who doesn't face it with some sort of dignity (excluding Terra-Xehanort and Young Xehanort, as only Xehanort vanishes from Terra's body and Young Xehanort dies taunting Sora).
