>>21392061Groudon/Kyogre/Rayquaza aren't really based on Behemoth/Leviathan/Ziz. Primeval beasts of land, sea, and air isn't an uncommon concept. Articuno and Zapdos aren't exactly based on mythological concepts either (before you say thunderbird, besides the connection to storms Zapdos has pretty much nothing in common with a thunderbird and at best it's a very loose inspiration).
>>21392297Cutting down on the legendary Pokemon for this gen, since there's also a smaller number of new Pokemon in general. Percentage wise, it's up there with Hoenn and Unova.
