Narrative about opponents fighting each other to the death

Long descriptive narrative, with Dialogue 

a long narrative about a realistic battle for both opponents, Please do not use any overpowered or ridiculously strong characters, it will break the Rule logic and make the battle not make any sense. 
These Rule battles are meant for imaginative and fun characters, so you are free to improve your characters anyway you see fit to make fights epic, that includes making your characters abilities more profound and wild, so that they not only give you a Fighting chance, but they make the fights epic. If you're characters are bad in some aspects and you don't want to change that, give them improvisation. If your characters have an ability that works but not how you thought it would, change it to how you see fit. All characters are judged fairly and equally.
