The Dwarves keep saying Usoland will help them for he is a hero. Trebol tells them he was just lying and starts squishing them, Usopp appears and tells them he was lying but he will go down fighting as a true hero and attacks Trebol. Kyros picks up a sword believing it to be good against doflamingo as he remembers when he was 15 how the King brought him into the colosseum as punishment for murdering someone. Kyros fought 100 people going to 200, 300, 400, all the way up to 1000 people, but it didn't matter anymore as people would always see him as a beast.
