Who is stopping him right now? He is now the strongest Yonko unless Big Mom is somehow stronger (lol). I don't think anyone in the Government can lay a hand on him. Amd for sure it isn't simple to get there, but he was on the ship when they did get there.Kyo said:He can't progress, let alone go to Raftel, because of the govt and the other Yonko. Also I would imagine that he just doesn't know how to get there. Given the way Roger talked about the way to get there to WB I imagine it's not as simple as just sailing until you find it at the end of the Grand Line.
Shanks was able to stop Kaido from attacking Whitebeard at Marineford and seemed to take no damage, implying that he never fought Kaido. Kaido seemed to avoid fighting him for some reason, but as you said, the crew itself is likely a big factor.Kyo said:I'd imagine Kaido is stronger than him, and the strength of their crews and fleets is probably the more important factor anyway
All of the admirals can definitely lay a hand on him and Akainu could probably fuck him up, but either way that's why both the entire government and the Shichibukai (admittedly just Mihawk at this point, really) exist among the Great Powers
