@VinMcCarthy You really got me on this one. By far this was the hardest theme to come up with a specific person or anime for. Although it might be cheating a bit as its not a natural ability, I have to go with Portgas D. Ace.
His ability to control fire and essential become it gives him a great defense against normal enemies that font possess a devil fruit power.
I chose him because it was an ability I always found the most interesting of the Devil fruits within One Piece. I absolutely love this ability because it's so strong and versatile. He uses his fire for protection, offense as well as defense, traveling, and signaling. It's an ability that is simple in theory, and yet complicated when your begin to imagine everything he could do with it and yet chose not to.
