In KH1, Sora gets Oblivion after beating Riku in Hollow Bastion the second time in a chest around the area that Sora fought him.
In kingdom Hearts 1, the best Keyblade is Oblivion, obtained in Hollow Bastion. In KH2, you have to synthesize it.
The Oblivion Keyblade is given to you right before entering the castle at The World That Never Was, towards the end of the game. Riku gives the Oblivion to Sora.
The Oblivion Keyblade is the strongest Keyblade Sora can wield except for the Ultima Weapon, which is made through synthesis. The Oblivion is mostly black and purple with a cool design. The Oblivion is also known as the Dark Blade, which is opposed to the Light blade called the Oathkeeper, the blade given by Kairi.
ansem does after his blade is destoryed by sora which was formed by the princesses hearts or was it kairi can;t remeber but one of them
Yes, Sora is a chosen keyblade master. He is the main Keyblade wielder, the second being King Mickey. Sora was chosen to be the keyblade master because of his powerful heart and strength. SPOILER****************** Terra wanted Riku to be the keyblade master, but Sora's heart was more powerful, thus Sora was able to combine his heart with Ven, allowing him to wield any keyblade.
Riku is seen with the Oblivion when Roxas fights him at Memory's Skyscraper in Kingdom Hearts 358/2 Days. He also wields the Oblivion when Sora fights him in Hollow Bastion in Kingdom Hearts 1.
The Keyblade chose Sora in Destiny Islands. Sora's first Keyblade was the Kingdom Key, but it changed into different versions, like Hidden Dragon, Circle Of Life, etc.
The Keyblade chose Sora because he has a strong heart and would do anything for his friends.
... do you mean Xion? If so, Xion isn't Kairi's nobody, Namine is. Xion is simply the result of an experiment in Castle Oblivion on Sora; she's an "imperfect replica of Sora". That's why she's able to wield the keyblade
Because it was his understanding that Sora and Riku were the only wielders of the Keyblade.
The strongest keyblade (in terms of attack power) is the Fenrir Keyblade.
Sora CAN in fact give the keyblade to someone else, but that doesn't guarantee that it will work for them. Plus, it always returns to Sora because he is the destined wielder of the keyblade.
