|“||Graceful yet Violent.||„|
|~ Rey Kivat's motto before battling an enemy|
Rey Kivat is an intelligent computer created by 3WA. He can transform Takato into Kamen Rider Rey. It is not an original Kivat because it was created by humans. It also blows the Key Fuestle to unseal Kamen Rider Rey's main weapon Gigantic Claw.
Rey Kivat is calm and passionate, but does not enjoy destroying his enemies, unlike Arc Kivat.
