Roxas is a key character in the ever-complicated story of Kingdom Hearts.
Roxas was created when Sora released his own heart to restore Kairi’s, making Sora become a heartless for a short while but long enough for Roxas to come into existence. Thus Roxas and Sora co-existed but Roxas lacked any memories. And Roxas being Sora’s nobody, he obtained the power to use the Keyblade, something Organization XIII needed to achieve their goal. Therefore Roxas became the 13th member or Organization XIII.
Axel and Roxas and later Xion become best friends. But once Xion learns the truth about her origins she escapes the Organization and later forces Roxas to fight her. After the intense battle she dies in Roxas’s arms and vanishes becoming part of Roxas. This causes Roxas to be able to use 2 Keyblades. He then runs from the Organization where he encounters and battles Riku. Riku defeats Roxas after unleashing tthe darkness within his heart and taking the Appearance of Xehanort’s Heartless. This is where DiZ comes into play and places Roxas in the Virtual Twilight Town where Kingdom Hearts II begins.
DiZ’s goal is to unite Roxas and Sora so that Sora may regain all of his memories and strength after the events of Castle Oblivion. DiZ somehow changes Roxas’s memory so that he believes he lives a normal life in Twlight Town with his three best friends Hayner, Pence, and Olette. As Sora’s memories are restored by Naminé, Roxas begins to see flashes of these memories. Roxas encounters Naminé, Riku, and even has a connection with Kairi. The Organization sent Axel to find Roxas and bring him back. DiZ stops Axel from capturing Roxas and tells him to go to the Old Mansion. Here is when Roxas learns he must reunite with Sora to become whole. Naminé tells him that they will meet again even if they do not recognize each other. Axel tries to stop him, but Roxas, with regret, defeats him. Roxas then rejoins Sora to become his original self.
During most of KH II the Orgainzation members refer to Sora as if he is Roxas. This is confusing the first play through KH II but one a second play through it makes perfect sense. When Axel dies after saving Sora before entering The World that Never Was, it awakens Roxas. Roxas then attacks Sora, wondering why Axel sacrificed himself to save Sora. Roxas then realizes that Sora is who he is because of his friends. This is all takes place in Sora’s mind as a mental struggle between the two.
Roxas appears beside Naminé before Sora and Kairi before the final battle. They are all happy to meet again and become whole. As long as Sora and Kairi are together, Roxas and Naminé will be together.
Now why do Roxas and Ventus look so similar? Since Ventus’s heart resides inside Sora’s, when Roxas was created his appearance was influenced by Ventus’s heart. In fact Roxas’s 2nd Keyblade is Ventus’s keyblade awakened after many years. Since Xion became part of Roxas, their keyblades became the same.
Roxas is a key character in the story and plays a big role throughout KH II.
