Way to Dawn from KH2
The exact time when Riku got his keyblade is unknown, but it's sometime after Sora encounters him in Land of Dragons. When Riku appears in The World That Never Was, he suddenly has this keyblade with him. The Soul Eater Riku has was used as an intermediary for the creation of his keyblade. This is why the appearance of Way To Dawn looks so similar to Riku's former weapon. Since Riku has always been using Soul Eater since he first obtained it, he still calls Way To Dawn that. This keyblade could be taken as the one from the world in-between. He is considered a keyblade master since Xemnas referred to him, Sora and King Mickey as one. He and Sora use their keyblades in the final battle against Xemnas.
