So Ven,Terra and Aqua visited Neverland, radiant garden, and they met Peter pan and Merlin. So in kh1 Sora went to Neverland and met Peter pan. Didnt he mentioned anything about Ven , Terra and Aqua? I mean like "Oh i have seen a keyblade wielder again" and stuff? What about Merlin? Really? HE IS A WIZARD!!! Or Mickey...Why didn't he said anything? Not a thing until the ending of kh2! This topic is kinda weird i know

Peter didn't say anything because his character is meant to be young and irreverent. Merlin has terrible memory. Mickey and Yen Sid had no reason to tell Sora (And we don't know if they told Riku)

I'm sure it will be explained in the game after Dream Drop Distance.

Well with Peter, he probably didn't see it as significant. Merlin, as Hatok says, has a terrible memory. As seemingly many residents of Radiant Garden have, if they can't even remember the real name of their home world. As for Mickey, there was never any time to really talk about it. The whole thing about Ven and everything probably slipped Mickey's mind and he didn't see it as important until Re:coded, where he learnt what Ven and all's connection to Sora is.

maybe mickey didnt tell sora them because they werent ready yet

its simple to answer this when they made kh1 they had no idea they were going to make bbs so ven aqua and terras characters had never even been thought of yet simple

Basically it must be that, what Josephmahon1 said.

 

And I think there won't be any answers any time soon.

 

Only with Mickey and Yen Sid, probably.

As josephmahon said, they didn't think of the characters at that time, so their excuse is pretty much everyone forgot about them. Like when everyone temporarily forgot Sora because of the events of CoM, though they remembered him afterwards.

Probably because when they made Kingdom Hearts 1 there was no intention to continue the series. So Ven, Aqua, and Terra werent even though of yet, so they couldnt have been mentioned. Also this may come as hard to understand, if you arent familiar with the legend. But Merlin lives time backwards. So and event that happened afterwards to him happened before.

As for Peter Pan. For me it seems like a lot of the reoccuring worlds are only in the game for the sake of developing the characters' abilities. Since there doesnt seem to be another Disney movie that I can think of where the character's have the ability to fly, there is little other logical reason for them to gain the Glide ability. You could send them to Angel Island to learn from Knuckles, but I find that crossover unlikely.

During TGS it was mentioned that during the demo, Riku is flying. So the real question that should be asked here is: Why can Riku fly? He never met Peter Pan, and the only villain who can fly is Dragon form Maleficent and Anse- oh never mind I think I just answered my own question.

But yeah, I dont think we will be seeing any more of Peter now that everyone who needs to, can fly.
