The Oblivion is a Keychain for Sora's Keyblade which appears in Kingdom Hearts. It also appears as half of Roxas's dual set of Keyblades alongside the Oathkeeper, and was transformed from the second Kingdom Key Roxas obtained after absorbing Xion. Fundamentally, the Oblivion is symbolic of Sora's memories of Riku. Oblivion is similar in shape to the Kingdom Key, though is black and has a longer reach. The hilt guard is comprised of two bat-like wings extending downward. The teeth are in the shape of the Kanji for "darkness". The Keychain's token is a black version of Sora's crown necklace. A chain-like design runs up the length of the blade.
