Because Jack was too prideful to use it lmao
Shows again that Jack was not serious/or without 100% if his hybrid form can match Sulong Inu who is >/>> to his base form.
Imagine if Jack really even put out awakening.
Jack should not lose to Inu
I was kinda disappointed when Jack get trashed by two sulong minks, but however Jack has the chance to proof himself to stand above at least one sulong duke, kinda incredible hype for him if he take out one of the Sulong Minks, since Kaido even hype them as beasts:
If Jack can win or even pull out awakening, im fine with both things and wouldn´t even matter if Luffy smash him after he take out Sulong Inu.
Issue with that is Jack is inside in the Middleish and momo has no reason to not fly luffy straight to the roof.
Only way: Jack crush Inu out of them dome who land in the open area and before Jack can finish him, Luffy come and save him.
I can see a whole one chapter with Luffy using different skills and attack until he beat Jack.
People should not forget, Blueno was defeated with a new move, perhaps it happen here again with Luffy pulling out something new.^^
