I don't know why I still go with Axel in this battle, I mean it would seem Axel could find a way to out smart Deymx.
Cause you gotta also think about their skill level aswell. And Axel seems much more experienced. And uses his head in battle more.
Deymx would put up a good fight...its hard to say a clear winner, with the water over powering the fire....but still if Axel puts out enough fire he can over Come Deymx's attacks, cause think about it, you know how much water it takes to put out a house fire, and Axel can continuously spread and fuel that fire, making it stronger and stronger. So in other words it would be like a hose trying to put out a house fire or a forest fire even. It could work but it would take some time......
