did you forget Hades, it absorbed him after he was killed, and could use his powers, so if he absorbs the soul of the chariman, he will absorb all of his knowledege, and it's game over for Fairy Tail, especially if Kyouka fights Erza and Minerva during that time ( that would explain why Mashima stopped the previous fight )
