Flame of Wrath

From Reborn Wiki

The Flame of Wrath aka Flame of Rage, as described by Reborn is: "The Dying Will Flame is like a fingerprint or a voiceprint. It is unique to each individual, differing in both form and nature. And Xanxus's shining ball flame is exceedingly rare. Among the Vongola Bosses, the only one who fought with bare handed was the 2nd because of this flame. The special characteristic of this flame is its extreme destructive power which can reduce anything to ashes. Also, this flame was seen only when the 2nd Vongola boss was enraged, so now it is called the Flame of Wrath to differentiate it from the Dying Will Flame."

In the Future Arc, the Flame of Wrath was shown to be have properties and effects similar to that of a Storm flame due to its destructive nature.
