Biography
This mysterious person appears before Roman 17 years prior to the pilot at the famous Nazca Lines, claiming that Roman should be the one in control of the experiments on the Old Enerdy, even if it means getting rid of Dr. Fudo. He also seems to be quite knowledgeable of the 5,000 year old conflict between the Signers and Dark Signers, acknowledging Roman's Dragon Head Birthmark. After briefly conversing with Roman, he simply disappears into a sandstorm. While not much is known about this man, or his intentions, considering that he was responsible for Roman's fall and the Zero Reverse, it is likely he will show his true face in the future.

Dark Signers
After Yusei Fudo defeated Grady, he conversed with Rex about the Dark Signers making their move.



He also appeared later when Rex went to confront his brother, Roman, conversing with Lazar, confirming Rex's actions, and stating that the world has been waiting 20 years for them to make their decision.
