Damn, its pretty hard to come up with a decent looking seeming legendary pokemon..far worse, figuring out what it will reign over, seeing as how pretty much everything has been covered.
Though it was slightly touched upon in Sapphire/Ruby, with Kyogre being able to make it rain endlessly, I decided, if I was to make my own Pokemon game, to base the legendaries on weather.
Such as this guy, based onthe leviathian, though not from the start, it came after I finished, its domain is the sea. When enraged it causes the oceans to churn in chaotic turmoil, wave upon wave, pummelling any would be sailor, destroying their ship, and drowning its passengers. It has no remorse for this it kills, be it on purpose or accidental. Its said, that if you were to see it when the seas are calm, it will bring you all sorts of good luck, however, if you so much as to anger it, there will be ten years of bad luck upon you with any body of water.
I dont know what to name it, or what type to make it, I though, Dark/Water, perhaps? or Ghost/Water?
I dont know, also, I need a name, give suggestions!
Ill probably redraw this later, in pencil, this was done in Flash. Woo.
Edit: It is now a GHOST/WATER type.
