well as much as i dont like to talk about fights that will more than likely never happen BUT, we also have to remeber a great deal of enels strengths came from his mantra letting him predict the movements of others.... can this be done with a guy who moves at such a high speed? Well no, because luffy at some points as already beating his mantra in terms of speed, add to the fact that im pretty sure all the admirals will be as experienced as silvers at fighting logia users and will be able to hit them just like silvers did......... there is a high chance enel has never encountered anyone as strong as himself.
