More aboutL Oblivion Keyblade
The Oblivion keyblade 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". The keychain's token is a black version of Sora's crown necklace. A chain-like design runs up the length of the blade. When the Oblivion is summoned in Kingdom Hearts II, black smoke and violet sparks surround it.
