Article summary:
Defeated by Luffy at Skypiea, the false god Ener (Enel) is not dead. He achieved his crazy dream: reaching "Fairy Vearth," which is none other than the Moon. In a canonical adventure (the manga's Cover Stories) completely ignored by the anime, he discovered an ancient underground city, a hidden history about the origins of the sky peoples, and an army of robots. In 2026, as the Ancient Weapons and the technology of the Void Century resurface with Vegapunk, the return of the God of Lightning is one of the most credible theories for the final war.
Ener possesses one of the most powerful Devil Fruits in the One Piece universe: the Goro Goro no Mi (Rumble-Rumble Fruit). His ability to destroy entire islands rivals that of the Ancient Weapons. If he returns to the Blue Sea with his newfound lunar knowledge and army of automatons, he could overturn the fragile balance between the Emperors, the Marines, and the World Government.
But what exactly is he doing up there? And what is the secret connection between his discovery and Dr. Vegapunk's research?
The God of Lightning now rules over outer space and the lost city of Birka.
The Ancient City of Birka: The Secret of Our Origins
Once he reached the Moon aboard his Maxim ark, Ener did not simply admire the void. He fought Space Pirates (yes, they exist!) and fell into a crater leading to a vast underground city. The name of this city? Birka. It is exactly the same name as the sky island where Ener was born and which he destroyed in the past.
The murals he deciphered change the entire history of One Piece. They show that the ancestors of the three winged peoples—the Skypieans, the Shandians, and the Birkans—all lived on the Moon long ago. They descended to Earth ("the Blue Sea") when the Moon's resources were depleted, leaving their robotic creations behind.
This revelation is crucial. It connects the sky peoples to the mystery of the 800 years. The "Gods" of this world may literally come from outer space. To understand how this fits into the great hidden history, read our feature: The Void Century: What the Government Is Hiding from Us.
The Army of Automatons and the Connection to Vegapunk
On the Moon, Ener found thousands of small soldier robots lying dormant. Using his lightning, he reactivated them all. These automatons are now completely loyal to him. Unlike human pirates, they know neither fear nor pain.
The design of these robots is eerily similar to the creations of Dr. Vegapunk seen on Egghead Island and the famous ancient "Giant Robot." This suggests that Vegapunk's "futuristic" technology is actually "ancient" technology from the Moon. Ener holds the key to the infinite energy the world is searching for.
Ener's legendary expression when he realizes that Luffy is his natural enemy. Imagine his face when he sees Gear 5!

A Rematch Against Luffy Gear 5?
Luffy is Ener's only natural enemy (rubber insulates against lightning). That was the reason for his defeat at Skypiea. But today, Luffy has awakened his fruit and become the Sun God Nika.
A rematch would be mythological: Zeus (Ener) versus Apollo (Luffy). Ener considers himself an untouchable deity. Seeing Luffy in his white form, catching lightning bolts with his bare hands and turning the ground into rubber, would be a total psychological shock for him.
Many also theorize that Ener will descend in pursuit of the Ancient Weapon Uranus. The recent destruction of the kingdom of Lulusia by Imu, using a celestial weapon that fires beams resembling lightning, bears a strange resemblance to the power of the Maxim ark.

Conclusion: The Threat from Above
Never underestimate Ener. His chapter-cover story is too detailed and rich in lore to be merely a simple bonus. He will return, and he will no longer be alone.
