Imagine having no high class genetic power ups, like others. Imagine not having a absolute top tier trainer for 2 years. Imagine not getting help by whole rogers crews, shanks, half of the marines and some warlords. Imagine not getting power ups out of nowhere, like a magic sword or some high tech suits. Imagine not having the biggest Plotarmor available, where even a first mate of an Yonko nerfs himself to fight you.
But even without all that, you build a great crew and going for the heads of Yonkos. Standing your ground against Yonkos, not getting stopped by losing an arm. Not getting stopped by humilating. No, straight forward going, your goal in your eyes. Nothing can stop you. Even if all you have is yourself and your friends.
