ACE'S TRAINING

Rex was trying to train Ace, he has unlocked his all power and was fighting with Ace and now the fight starts ~ Ace with his god speed attacks Rex and cutted his both legs and head but then we got to know that it was just Rex's dummy statue. Rex was behind Ace but doesn't know, Rex with his right hand fainted Ace. When Rex met Akira he said that he is now so strong, I think that he would be the Fastest and faster than Hermes.
