Hundred Beast Pirates Governor - General Kaido
Koala, having dugongs as her disciples, taught them Fishmen Karate.
Momonosuke got anxious from Kaido's dragon form. Law informed kinemon that Kaido already knew their identities. However kinemon's coup d'état plan is still unknown to the enemy. Luffy got worried then quickly headed towards the town where Kaido appeared. Then both Kinemon and O-Kiko follow luffy as they are worried to for O-Tsuru.
In Bakura Town, as the townsfolk and bandits panic, Kaidu talks to Shutenmaru down and somehow remember him. Shutenmaru then recall that he once fought a dragon. However, Kaido seems to be drunk and was happy to invite Shutenmaru to his crew and he would forget about their past. Suddenly, Hawkins quickly tip Kaido the whereabouts of Luffy and the others. Kaidu rushed to Oden Castle then attacked with his gigantic mouth 'Borobreath'! Everyone was shocked, while nami and the others were in hysteria in preparing for an escape. Then at the end of the chapter, a silhouette appears right above Kaido.
'Gomu Gomu no Elephant Gun!'
Luffy was furious and hammer his fist on Kaido's head in one hit.
