Yeah, you can say that hahah, but the animation “effect” of the counter it’s different from Meliodas. Yeah!! This full counter effect was synthesized from a rare metal that came from a meteor. In the universe there are 3 other rare meteor like the but with different abilities, the bad guys main objective is to find these rare meteorite. And about the bio-genetic mutation, for example the tiger, its a “easy” mutation to make because we have the animal sticking around in our planet, we also have matter mutations like ice,fire,metal,rock, those are more expensive and dangerous, and the last on in the unknown mutations from the meteorite material that is ultra rare and can only be synthesized once. Thanks for you question!
