The Big Mom Pirates arrived at Wano Country with the intent to kill Luffy. Alongside Big Mom, we saw many of her children like Smoothie, Perospero, Oven, Daifuku.
The glaring absences here are Cracker and Katakuri, who likely stayed in Whole Cake Island.
This has led many people to speculate that Blackbeard will invade Whole Cake Island, fight (and maybe kill) Katakuri and take what he wants (the Road Poneglyph).
Professor Gemini realized his amitious project by drawing 20 pages of Blackbeard Pirates vs Katakuri fight.
The characters, the dialogue, and most important, the art.. everything here is just amazing!
