"Because those four cards contain the energy of the universe. En Moon harnesses the power of the cosmos, while En Winds helps the force of storms and gale. En Birds contains the life force of all the living creatures, and En Flowers was the very power of the mother nature herself." - Ray explains the power of four cards to Riley [1]

The Natural Energy Cards are a series of Continuous Spell Cards used by Ray Akaba for the purpose of combating Supreme King Z-ARC in the Yu-Gi-Oh! ARC-V anime.

According to Leo Akaba the purpose of these cards was to harness the natural energy of the planet to equal and counter the malicious aspects and energies of humans that metamorphosed Zarc into his fiendish draconic form, effectively reverting Zarc to that of an infant .[2]


Leo Akaba investigated a method to stop Zarc's fused form. By traveling the world and following the theory of Duel Monsters with souls while researching different natural environments, Leo was able to create four Spell Cards subtitled under the names "Flowers, Birds, Winds, and Moon" from the natural energy that he believed would be able to counter Zarc. Through analyzing and studying the desire of plants that are destroyed but sprout with the seasons and animals that endure winter to survive to spring he was able to fulfill his objective. The audacious desire to live that has manifested in the world for hundreds of thousands of years. This generated a robust energy that Leo hoped to utilize to halt the dark emotions and surpass Supreme King Z-ARC. However, when Leo had just finished creating the four cards, Ray stole the cards as she could not bear the thought of losing her father.[2]

Leo gave chase to his daughter but she activated a card, destroying the surrounding buildings and blocking his way with rubble. Leo then took a different road and eventually saw Ray, confronting Zarc, as she activated the four cards, causing the related natural energy sources of flowers, birds, wind, and the moon to react and converge within Ray's body. The reaction of natural energies then created the Four Dimension Bracelets on Ray's right hand. The natural energy convergence then caused a reaction in both Ray and Zarc's bodies, and subsequently de-fused the Supreme King Dragon from his dragons as well as Ray's and Zarc's original bodies into four, creating their Dimensional counterparts and the Four Dimensions.[2] The cards themselves then manifested as Four Dimension Bracelets worn by Zuzu Boyle, Celina, Rin, and Lulu Obsidian, Ray's incarnations.

Later, the bracelets were transformed back into their card form when Leo attempted to reunite the four girls back into Ray. The four cards were then used by Riley Akaba to defeat Zarc and seal his evil spirit for good, again, manifesting as the four bracelets on Riley's wrist. While their status afterward is unknown, Declan confirmed in the English Dub that the cards perished after the battle due to having used all their power.

Playing style

Natural Energy Cards' playing style starts with the game having many Fusion, Synchro and Xyz Monsters in the GY or banished. When gathered, they're activated as quickly as all at once. After all of them are activated, which would have Fusion, Synchro and Xyz Monsters' Effect negated and them treated as Normal Monsters, they are destroyed with "En Flower" and would severely damage the opponent.
