Swaziland is a very small country, if we use countries like that even multi city busters are going to be country level characters.
Malta is a country of just, 316 Sq km. There are cities bigger.
Some states are bigger than countries alaska is 1,717,854 km²
But we did get a average from comparing 194 countries. Which is 767 731 sq km. Roughly 44 times bigger than that island.
Fact remain is that island is still in a island size . It doesn't even come up of on the top 15 - 20
That's still a unproven statement, Coco hasn't even shown potential of that sort . if cells solarsystem busting statement is a hyperbole then this applies to the current situation much more. Atleast cell did something, here it's nothing but a vague statement, to point our they were holding back .
It's bigger than the average island that's for sure, technically it should be bigger than Hawaii since Hawaii it's separtated into parts and when being scaled is counted for its water as well. The fact remains though that country level + on the OBD is about that size. Why do I know this? Because I've seen SO MANY arguments go down there about Naruto's so called 'country level' attacks when they're no bigger than cooking island. Soooo since we're going by their standards as you are, this is country level.
Also, vague statement? No, Unlike Akira Toriyama Shima actually means what he writes, so much so that he is willing to write the fine details of attacks and strength during his battle. So what you just said is invalid. Now about Coco being capable of doing so, I agree. He gets his strength from Potency and Hax. But the fact remains that while Toriyama's and most shonen writers statements are hyperbole, Shima's statements in Toriko have been time and time again backed up by his characters. So whether you believe it or not is not an issue with anyone else here.
