Oblivion



The Oblivion (過ぎ去りし思い出) is a Keychain that is found in Kingdom Hearts, Kingdom Hearts: Chain of Memories, Kingdom Hearts II, and Kingdom Hearts 358/2 Days. 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.

Appearance
Oblivion is similar in shape to the Kingdom Key, though is deep 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" (闇). The keychain motif is a black version of Sora's crown necklace. There's a chain in the middle of the blade, in the Deep Dive video it can be seen it's a hole with a chain on it (you can see through it around 1:10-1:15) while in the official artwork and the games it's a solid blade without any hole on it (yet you can still see the chain). The diamond in its hilt also resembles the diamond in the original logo of Hollow Bastion. When the Oblivion is summoned in Kingdom Hearts II, black smoke and violet sparks surround it.

Other Appearances
A limited edition Oblivion was released with four other Keyblades in a special Play Arts Figures accessory set, Play Arts Arms.
