Kingdom Hearts Re:coded
Data-Sora encounters a black-coated figure in the Dive to the Heart. Although he later guesses the figure is Data-Riku, who himself initially wears a black coat, Data-Riku informs Data-Sora that their first meeting was on Destiny Islands, leaving Data-Sora to wonder who the first figure was.
The mysterious figure appears again in Castle Oblivion, giving Data-Sora a World Card for Destiny Islands. After obtaining one of the ending cards, the figure returns to give Data-Sora the World Cards for Wonderland, Olympus Coliseum, Agrabah and Hollow Bastion. He returns after the player obtains the first ending card for each world, mocking Data-Sora for forgetting the people that he thought were important, and advising him to just forget everyone in the illusions, as the hurt from not remembering them would be too painful. However, Data-Sora rejects this idea and tells him that he would keep the burden of the hurt on his heart until he remembered his friends again. After at least one ending card from each world is obtained, the figure challenges Data-Sora into a fight to show him "the true hurt". After being defeated, the figure reveals himself to be a data version of Roxas, and gives Sora the final World Card.
Data-Roxas takes the form of Roxas wearing his Black Coat with the hood up.
The bugged version of Data-Roxas is completely black, resembling a silhouette, and wields dark versions of the Oathkeeper and Oblivion Keyblades. Data-Roxas's body and Keyblades are covered in and surrounded by glowing, blue panels resembling computer screens.
