You are the most wanted pirate captain, you are a yonko and have a bounty almost the same as Shanks. When a fierce battle occurred you suddenly appeared above them all as if flying without wings then shouted at mihawk in a loud voice while waving "Brother, long time no see" Mihawk looked up at the sky while looking at you with a small smile. When you came down to hug him he smacked your head and said "You idiot, where have you been I was worried about you all this time."
