If you can make a world from any anime, video game or movie what would it be.

If you can make any world from a anime, video game or movie. What would it be and what kind of heartless,nobodies and unversed would you but in it. Also what areas would be accessible and what would the world be called and one last thing. What kingdom hearts would you put it in and what characters would you see. Also (and this is optional depending on your world) what character would be a assist character.
Like for example here is mine world idea.

Name - City of the violet moon
Based off - Chibi Vampire
Heartless - Shadow, Soilder, Dark ball, Behemoth, Large Body, Red Nocturne, Blue Rhapsody, Yellow Opera and Gargoyle
Nobodies - Dusks, Dancers and Samurais
Unverseds - flood
Accessible areas - Kenta's house, School court yard, Home room, Maaka house, Julion's restaurant
Characters - Karin, Kenta, Anju, Ren, Henry, Calera, Fumio and Maki
Assist characters - none
In which kingdom Hearts - Kingdom Hearts 2 and Dream drop Distance

(I don't mean this to be a role playing thing. I just thought that other people might have ideas for worlds for kingdom hearts.)
I hope you guys got awsome ideas.
