Thanks to the development of the ARC System developed by the Leo Corporation, Duel Monsters are now given physical matter, giving birth to Action Duels. At Paradise City's You Show Duel School, a young duelist named Yuya Sakaki is approached with the opportunity to duel against the current Action Duel champion, The Sledgehammer. This brings back memories of three years ago when Yuya's father, Yusho, mysteriously disappeared before an important match with the Sledgehammer. After deliberation, Yuya shows up to face The Sledgehammer in an Action Duel. Sledgehammer quickly brings out his ace monster, Battleguard King, with Yuya evading his attacks by using Action Cards found across the environment. Yuya summons out Odd-Eyes Dragon to attack Sledgehammer but things turn around with his own Action Card that deals damage to Yuya. Just as Yuya is at his wit's end, he remembers encouraging words from his father as well as the pendulum his father left with him. Just then, his necklace glows and transformed some of his cards into Pendulum Monsters and allows him to perform a new summoning called Pendulum Summon. Yuya summons out several monsters, which includes an enhanced version of Odd-Eyes Dragon known as Odd-Eyes Pendulum Dragon.
