Moreover, the most important thing is that while the Fire Series is incredibly powerful, it is one of the Five Elements. Facing its counter elements—the Water Series and Ice Element—Fire Series can only exert 500 points of destruction. After accounting for the opponent's defense and resistance, it's reduced to around 300 points.
However, the Thunder System is different. It doesn't belong to the Five Elements, and no person, object, or entity can be immune to or resist the damage dealt by the Thunder System. Its power is absolute; it doesn't change because of anything.
In other words, before the Thunder System, all beings are equal. No matter what series or element you belong to, the power remains the same. Under the Thunder System, everyone is equal. Although its total destructive power is secondary to the Fire Series, its absolute destructive ability surpasses that of the Fire Series.
