Shock
Ronan stared at the massive pheonix coming at him and he knew at that moment that he needed to give it his all to defend.
The only problem was that while his thunder element was an excellent superior element that probably had the highest damage index , great for attacks it was also the weakest one when it came to defense.
Lightning could simply not mount proper defense against attacks like these and the best defensive lightning move that Ronan knew was simply lightning shield which was a D ranked move that could be blown away by simple punches.
Under such circumstances his only bet was to use fire as his defense, but his fire elemental affinity was not even 2% , it was so pitifully low that technically he should not be able to even produce C ranked moves with it , much less produce something potent enough to defend against this A ranked move that Percy had just launched.
Under such circumstances, Ronan knew that he had only one option, which was to attack even harder !
