Gaban told luffy
-be careful how you use coc
-those guy aint immortal so in other words they can be scarred and even killed.
lets look what gaban did to sommers

Gaban cut sommers in half and even cutting his arms off
looking at this panel gaban should've killed sommers off accordding to this words
"those guys are no means immortal"

Sommers fully healed couple minutes later
1)gaban didnt kill him
2)gaban didnt scarred him
sommers literally fully healed with no damage on his body
"those guys are no means immortal"
So gaban only temporary stopped sommers regen but not able to scar him or kill him.
The only answer is
A)gaban acoc is too weak which makes no sense
B)its more then just acoc
it reminds me of kaido all over again
Basic coa couldnt damage kaido
but internal and emission acoa had effect on kaido
but internal and emission acoc had even greater effect on kaido
what im tryna say is that gaban didnt use the new haki flow oda is gonna show
that new haki flow can be used for coa and coc
