Could literally have just killed Crocodile and this wouldn't be happening. He's the only one that knows, worse case scenario he is seen as a traitor and labeled as a pirate
To use chakra techniques no hand signals are needed, sasuke was able to use kirin as he didn't create hand signs so mc would have to focus on how to transform energy into the desired element
I don't think people are complaining about killing croc now, but being unhappy he didn't kill croc before for a logia and removing a future threat since he thinks croc will escape like canon eventually.
Why call marines at all just kill crocodile or call your sister to pick him up so she gets the credit atleast
This oc is an idiot debatably dumber than zoro
