Shay Obsidian

Shay Obsidian's powers and abilities

Like Yuto, Shay's Duel Disk possesses the ability to materialize the effects of Duel Monsters cards. The Disk also has the power to seal a person inside a card, though unlike previous uses of this power in the franchise, the entire person, and not just their soul. His Duel Disk is later upgraded with the function to produce an Action Field, and also appears to have dimensional travel technology incorporated into it. However, Declan modified it so that he could not seal a person anymore, and also seemed to have reduced its ability to materialize the effects of a Duel.[11]. Shay is highly acrobatic and athletic, as seen when he jumped off of the sides of several buildings and rolled along the ground to break his fall during his first Duel with Sora Perse. He is also a highly skilled fighter, strong enough to defeat several guards each with a single blow while escaping from the Facility in the Synchro Dimension.
