Cp-0 boss will just skywalk to somewhere else or luffy gets back up
Its not Impossible.
But i really think kaido Will murder Cp0 Boss.
What makes me even more confidente of that IS the lack os Denjiro in many chapters while the other scabbards were shown and Marco lack of doing something greater.
These 2 Will have great moments, oda was not hiding Denjiro for NOTHING.
I do think Denjiro, Marco and maybe even Jimbe and Yamato Will fight kaido while luffy can do It.
And i do see kaido also kiling Denjiro and even março and luffy going crazy and awakening his fruit.
Marco cant be in the final war again, is Just top repetitive. His plot ends HERE.
