Mihawk became one with yoru imo with something similar to zoan awakening
Leading to the sword becoming one with him and getting the double layered eyed and him becoming one with it and the sword becoming black
Roger didn’t
Imo Roger uses his haki similar to shanks/luffy and mihawk to zoro
- Roger with future observation and penetration armament
- Mihawk with overflowing armament and whatever zoro gets against shiryu
