Fakes should be destroyed!!
~ 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...
~ Repliku
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!
~ Repliku before battling his basis for the last time.
A faithful replica until the very end. That's... okay
~ Repliku's last words.

The Riku Replica, also known as Repliku, is a major antagonist in Kingdom Hearts: Chain of Memories. He is a clone of the original Riku given the memories of its model.



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 has its Heart was destroyed by Naminé in an attempt to calm its anger. After miraculously reviving it, it expressed that despite having no memories of its own it will protect Naminé, it is growing exponentially in strength, however it still felt 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 it 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 dies, finally at peace with itself as Riku tells it that its Heart will go to the same place his would.


In Dream Drop Distance, a doppelgänger of Riku appears inside Monstro, with Pinocchio, wearing the Organization XIII black coat. When confronted by the real Riku, the doppelgänger unhoods himself, but instead of confronting Riku, he immediately leaves. After seeing the double, Riku recalls his replica.

Later in Kingdom Hearts III it is revealed that this is actually a past version of Riku Replica that serves Organization XIII known as Dark Riku. He first appears in San Fransokyo and uses vast amounts of data to overwhelm Big Hero 6 as well as the heroes. He eventually reveals himself much to Sora's surprise and somehow travels to the dimension Callaghan's daughter was trapped in to capture the original Baymax and uses the data to turn him against the heroes much to Hiro's shock. Leaving the heroes to deal with Dark Baymax, Dark Riku leaves the world learning what Maleficent and Pete are up to as he does so. During the final battle, Dark Riku assists Xigbar in battling Sora and Riku, but the heart of the original Riku Replica excises Dark Riku's heart from his body. Dark Riku's body was later used to give Naminé a new body.


  • As a clone of Riku, the Replica is voiced by David Gallagher in English and Mamoru Miyano in Japanese.
  • The term "Repliku" is not just his nickname in the fandom; it is actually his official name in the German version of the games.
  • Among the 13 Organizations who died, Dark Riku is the only one who doesn't face it with some sort of dignity (excluding Terra-Xehanort, as only Xehanort vanishes from Terra's body).
