Combustion man vs. Deidara
Who wins this battle of the kings of combustion?
We have Combustion man, aka Sparky-sparky-boom man, from Avatar the last airbender. His known powers are super strength and speed, as well as the ability to shoot explosions from his mind. He can also create barriers around himself with his mind power that can be sustained for short periods. His weakness is his head, and if he suffers some kind of trauma or gets hit with a lot of force, his explosions can actually blow him up instead.
His opponent is Deidara, from Naruto. He starts off with two full pouches of clay, the amount he had when fighting Sasuke. His known powers are super speed and strength, and the ability to create living bombs and creatures from his clay that can make huge explosions. He also has a fail-safe suicide bomb technique that makes a 10 km explosion that vaporizes everything in the vicinity. His weakness is lightning, and if his clay sculptures are hit with lightning attacks they are rendered useless.
They both begin 25 meters away, in full health. Who wins?
