OG Dr. Vegapunk has a devil fruit. Wasn’t expecting that!
The Brain-Brain Fruit. It basically turned Dr. Vegapunk into a walking library. Which he then transformed it into an actual library. How exactly? It’s a devil fruit; Oda doesn’t have to explain it. Probably better if he doesn’t. Cutting off your brain, turning it into a digital library, then creating clones and giving them your mental Wi-Fi password is straight up magic. Let’s just accept it and move on.
Did you notice Dr. Vegapunk glitching? What’s that about? Is he dying? Is there a massive flaw to his Brain Library of Congress? Just putting it out there.
More power source talk. Yeah, that has to be why the advanced Ancient Kingdom lost. Something happened to their power source. Either it fizzled out or the Pre-World Government destroyed it. That would explain how they could possibly win against a country that advanced.
