"Funny thing about lightning," Luffy said as he began walking towards the statue. "It is 5 times hotter than the surface of the sun," He added before he punched the glass statue causing it to shatter into millions of pieces. "I think I messed around enough. Don't you think so?" Luffy asked rhetorically as he tilted his head to the side. "It's time to get serious," he added in a cold emotionless tone. Now Crocodile was slightly scared when he heard that. He just saw Luffy take care of one of his most powerful attack like it was nothing and now he is saying that he wasn't even serious, he was just messing around. That was absolutely ludicrous to Crocodile. Luffy narrowed his eyes at Crocodile before he kicked off from the ground and dashed forward towards Crocodile in a great show of natural speed. In a blink of an eye, Luffy appeared in front of the warlord and buried his knee into Crocodile's gut knocking the wind out of him and causing him to cough up some blood. Luffy then raised his left hand into the air made a fist before he delivered a powerful haki infused punch to Crocodile's back sending the arrogant warlord crashing into the ground while forming a small crater in the process.
