The last chapters of ONE PIECE laid the foundation for the clashes that will bring us to the conclusion of the Wa land narrative arc. On the one hand we saw the epic attack of the nine red scabbards, which were aimed directly at the Emperor Kaido, on the other hand it seems that each Mugiwara has found a certain opponent.
Driven by his extreme confidence in his own abilities, Kaido initially underestimated the Kin'emon-led samurai groupwho also turned out to be a skilled strategist. The warriors had actually calculated that their attack would take place on a full moon night, an event that allowed it Nekomamushi and Inuarashi take their sulong form.
As we have already seen in the past with the characters of Carrot and Pekoms, the mink, humanoids characterized by animal features, can only awaken their animal part on these nights in order to become stronger and faster.
In the further course of the chapter we see how both Nekomamushi, Cat-Viper, and Inuarashi, Dog-Storm, actually manage to face Kaido's crew. it is the emperor himself who claims that these forms made them powerful enough of being able to measure himself against his men. At the end of the news you will find the table with the Sulong forms.
Recall that Nico Robin came to life in a fantastic cosplay, and we'll leave you Oda's answer regarding the Chapter 1000 release.
