Due to retaining Ventus's heart, Roxas was able to feel emotions shortly after his creation,[4] unlike typical Nobodies who must first regrow their own heart over a long period of time. Being Sora's other half, his personality is similar to that of his counterpart, with some differences. For example, when Riku confirms that Roxas is Sora's Nobody after they meet in Dark City, Roxas's statement, "What are you talking about? I am me! Nobody else!" is nearly identical to Sora's later reactions when the Organization XIII members address him as Roxas.
