Background

Two centuries before Enel's era, the Logia's user was Thunder Dragon Alde, one of the Navy's foremost Fleet Admirals and the founder of the Great Navy Era 168.

Imu considered the fruit important enough to personally visit Sky Island. He regarded an awakened Rumble-Rumble Fruit as a direct source of electricity and speculated that it may have once powered Pluton 92. A previous awakened user had also used its power on Lightning Island, an area of near-constant thunderstorms that Imu later identified as a potential large-scale electrical power plant 717.

Enel found and ate the fruit as a teenager after encountering it during an adventure with his friends. Its appearance immediately stood out to him, and he consumed it out of curiosity despite its nauseating taste 351.

Appearance

When Enel discovered it, the fruit had a vivid, lightning-themed appearance 351.

• Golden body covered in radiating spikes.
• Green stem shaped like a lightning bolt.
• Produces blue electrical energy upon activation by its user.

Abilities & Skills

Lightning Elementalization

The fruit allows its user to transform into lightning, granting intangibility against ordinary obstacles and exceptional movement speed 351 354.

• Enel can move through crowds and physical obstructions while in lightning form 351.
• He can cross roughly one hundred meters and return to his original position almost instantly 354.
• Lightning can be condensed into offensive techniques such as Thunder Spear 697.
• Enel's lightning form can be disrupted by Armament Haki; Zephyr struck his transformed body with a Haki-coated fist 698.

Electrical Body Enhancement

Enel applies the fruit's currents to physical conditioning rather than relying solely on elemental attacks 487.

• Electrical stimulation produces the basic effects of Lightning Body Tempering 487.
• The fruit enhances Enel's Observation Haki range beyond that of his instructor 487.
• Its sensory enhancement lets Enel hear sounds within the range of his Observation Haki 487 2544.

Shockwave Integration

The Rumble-Rumble Fruit produces shockwaves when its power is used. Enel incorporated them into Hasshoken after finding Rokushiki unsuitable for his preferred combat style 697.

• Thunderclap Fist — a punch technique that combines Hasshoken with electrically generated shockwaves and sonic booms 697.
• Thunderbolt Leg — the leg-based variation of Thunderclap Fist 697.

Awakened Ability

Enel's awakening manifests as the God of Thunder, an armored lightning giant created by combining the fruit's power with his Teigu techniques 2569.

• The user's body becomes composed entirely of deep-blue lightning energy 2569.
• Fine-gold armor forms over the body and four additional lightning arms 2569.
• The additional arms wield a blade, spear, shield, and whip infused with Ryou 2569.

Limitations and Counters

• Enel experienced clear exhaustion after repeatedly using lightning movement shortly after obtaining the fruit 351.
• Armament Haki can physically strike the user's lightning form 698.
• Arbel is capable of completely nullifying the fruit's lightning damage, forcing Enel to rely on physical arts and weapon techniques during their battle 2569.

Relationships

• Enel — Current user. He calls the Rumble-Rumble Fruit the “strongest Logia” and develops its lightning, sensory, and awakened applications through military training 604 697 2569.
• Thunder Dragon Alde — Historical user; a former Fleet Admiral credited with founding the Great Navy Era 168.
• Imu — Recognizes the fruit's strategic value as a direct electrical-energy source and supplies Enel with development guidance 92 487.

Trivia

• The Plasma-Plasma Fruit is classified as an inferior Devil Fruit to the Rumble-Rumble Fruit 618.
• Vegapunk's future Logia-production plans specifically include creating Rumble-Rumble Fruits suitable for space combat through Complete Philosopher's Stones 2342.
