What is the bad guys name in kingdom hearts three

Well we don't really know if they are bad guys or not, but there names are Terra- Earth, Van- Wind, and Aqua- Water. their names are extermely simalar to Riku- Land, Sora- Sky, and Kairi-Sea. Which i believe indacates that they are not bad guys at all, but i guess we won't really know till 'Birth By Sleep' finnally comes out this year.
