 Kingdom Hearts II : Final Mix 's secret ending features a character named Ventus that bears a striking resemblance to Roxas . Nomura commented that , despite how similar they are , Roxas and Ventus are not the same character . Additionally , he stated that by playing Kingdom Hearts Birth by Sleep , players will be able to distinguish Roxas from Ventus . In another interview , Nomura implied both characters are related , specifically to Sora , but he wanted fans to imagine reasons for such connection . The Kingdom Hearts Birth by Sleep <unk> clarified the connection , stating that Roxas and Ventus look alike because Ventus ' heart entered Sora 's body and Roxas ' birth allowed Ventus ' heart to reside in Roxas . This also confirms the mystery about Roxas having a heart in contrast to other Nobodies which allows him to express emotions despite his lack of memories from a past , something that Nobodies use to show emotions .
