The devastating weapon known as Mother Flame has been mentioned alongside the Lulusia Kingdom in chapter 1086 of One Piece. Below are the shocking details regarding this dangerous weapon.
1. The Shocking Event in One Piece Chapter 1060

In chapter 1060, readers witnessed the horror brought by Mother Flame. This weapon was capable of annihilating the entire Lulusia Kingdom in mere seconds, leaving no trace behind.
Fortunately, after the attack, it was discovered that Sabo and a few Lulusian citizens (including Moda, a citizen whom Ace had previously helped) had survived at sea.
2. The Name Mother Flame Officially Revealed in Chapter 1086
Although we saw the destructive power of Mother Flame in chapter 1060, it wasn’t until chapter 1086 that we learned its name. Prior to this revelation, no one knew the exact nature of this deadly weapon, with some even speculating that it was a manifestation of Imu’s power.
Mother Flame is depicted as a massive fireball reminiscent of a sun, embodying immense energy.
3. The Creation of Vegapunk

In chapter 1086, Imu describes Mother Flame as a source of energy generated by the genius Vegapunk, though it’s still incomplete.
It was developed and produced at a power plant on Egghead, intended to serve as an unlimited energy source, a massive fireball aimed at propelling modern civilization forward, fulfilling Vegapunk’s ultimate goal of creating free energy.
The fireball is stored within a containment unit resembling a high-tech reactor, similar to a core that houses an immense power source marked with the production code “S-108”. This facility is located on the first floor of Building B at Labophase on Egghead.
4. The First Experiment Conducted in Lulusia

A prototype of Mother Flame on Egghead was showcased to the Five Elders and Imu. They utilized it to provide energy for an unidentified ancient weapon.
In chapter 1086, the Five Elders mention that Mother Flame has yet to be used for any experimentation. Saturn warns that it is uncertain whether it will succeed or fail during tests.
Initially intended for experimentation in a controlled area, Imu later designated the target: the Lulusia Kingdom. Warcury noticed many people in the vicinity, but Imu showed no concern, and none of the Five Elders opposed Imu’s orders.
5. Ivankov’s Suspicion of Mother Flame as an Ancient Weapon
Ivankov suspects that if “whatever is out there” can pierce through the clouds and devastate the land, it must be a weapon of the government, potentially only created by Vegapunk. However, Dragon asserts that Vegapunk could not create such a dangerous weapon.
Ivankov wonders, if it is indeed an ancient weapon, what does that mean?
