I disagree with EVERYTHING!!!
Riku at the moment has dark in him & is trying to find the light.At the end of CoM he was asked if he was going to take the darkness road or the twilit road and he said the road to dawn.Dawn means going from darkness to light.WHich also means he will have to master darkness to get to light.
since he is the real keyblade master
There is no REAL keyblade master just various keyblade masters.Riku is the true keyblade master & Sora is the original.
maybe only twilight are supposed to be keyblade masters
and the others are just messengers
I highly doubt that only Twilit keybearers are the only Keyblade Master.There won't be much of a game if only a certain "power" can wield a keyblade.
like sora was the messenger mickey could be a messenger
Sora was NEVER a messenger.In KH Riku said he was a messanger because Maleficent told him he has the strength in his heart to wield one which is true.But in Hollow Bastion Sora's heart grew stronger and got the keyblade back.If he was indeed a messanger I don't think the keyblade would've gone back to him now would it?And Mickey being a messanger is just hilarious.Mickey knows way more about the keyblade then anybody(i'll say) and him being a messenger for another keybearer I don't see it happening.
and maybe the worlds were originally twilight but then dark and light came
It was already said that long ago every world was filled with Light.BEcause people fought over the light and thats how darkness grew in their hearts.But light lives within even the deepest of darkness.
and the worlds mixed sorta and Riku left not knowing about his old life
I have no clue in hell what this is suppose to mean.
it would explain why Riku new about darkness at destiny islands
Riku didn't know about darkness.It was how he was seeing/feeling about things that the word darkness came out of his mouth & how it grew in his heart.
also it would explain why u where diffrent clothes on steam boat willie then u do in Disney castle which are supposed to be next to each other
You have different clothes in Steamboat Willie because SBW is an original world.Meaning anybody that steps into that world will be in their original form.Steamboat Willie & Disney Castkle are not next to each other they are the other side of each other.
then the keyblade would also be twilight
u see it changes, oblivion, to oathkeeper, light to dark
What keyblade?The Kingdomkey,inverted Kingdomkey(Mickey's keyblade),Oathkeeper & Oblivion don't & won't change forms.THey are original keyblades.The only reason why Kingdomkey(Sora's)changes forms is because of the keychain.BUt in originalty they don't change.(if you know what I mean)
P.S.Next time think about your theory because there is various mistakes in this theory of yours.
