EMS Release: Thermal Effect

Ace concentrates an exponential amount of EMS chakra around his entire body. Upon forming a final handsign, all of that chakra is released as heat energy. This heat ranges in the tens of thousands of degrees Fahrenheit and is so intense that it can melt sand into glass in a near instant, and vaporize as opponents body so fast that it leaves their shadow burned into the concrete.

It is said that Ace once used this jutsu to destroy a nation.
