"What? You want to join the Straw Hat Pirates?!"
Onboard the Thousand Sunny, a group of pirates and members of the Tontatta who had fought alongside Luffy in the Colosseum and were later saved by Usopp sent seven representatives, bearing brotherhood wine, to ask to join his crew.
"Indeed. We have all given this careful thought. Straw Hat Boy, you want to be the King of the Pirates, don't you? You should know that the ones closest to the throne right now are those four Emperors of the Sea. Not only are they formidable in their own right, but they also command countless subordinates. While your crew members all possess the strength of a hundred men each, it's still not enough. With the addition of our thousands of men, your crew will finally ascend to the rank of a great pirate fleet, giving you the confidence and standing to rival the Four Emperors."
