Ok there are somethings i know and i wanna share them!
Heartless:
They are the darkness that feed from peoples hearts if there heart is soo dark they turn into a heartless when struck down with a keyblade their hearts go staright to Kingdom Hearts!
Nobodies:
are like an "empty shell" that is left behind after a heartless is formed it takes a form of a creature with some random abilities also people with stronger hearts that are turned into a heartless (E.G: Sora) well a stronger nobody is left behind which is one of the members of Organization XIII ( E.G: Roxas ) Nobodies are like ghosts they wander around with no heart.
Organization XIII:
Now for the stronger Nobodies the members of Organization XIII are:
I: Xemnas
II: Xigbar
III: Xaldin
IV: Vexen
V: Lexaeus
VI: Zexion
VII: Saix
VIII: Axel
IX: Demyx
X: Luxord
XI: Marluxia
XII: Larxene
XIII: Roxas
XIV: Xion
Now these Nobodies are known as the strongest of the rest since their human selves had a strong heart also their original names have been jumbled around and had an "X" put into it (For example: Roxas is Sora, Xemnas is Ansem, Xigbar is Braig, Axel is Lea, Saix is Isa, Vexen is Even, Xaldin is Dilan, Lexaeus is Aeleus and Zexion is Ienzo.)
Terra's Story:
Ok so Terra was a young man who always dreamt of being a Keyblade Master but he had Darkeness inside him which his Master/Father didnot like but Xehanort did so he wanted Terra to build up his darkness...which did happen at the end of Terra's story on Kingdom Hearts Birth By Sleep, but Xehanort's dark heart fused with Terra's makin Terra as a Vessel for Xehanort's heart but he lost all memory of this after the fight with Aqua and was working For Ansem in the Radiant Garden, when the heartless were created however they stole Xehanort's heart then he was a strong Heartless but wasn't a tiny dark creature at all he looked like a younger version of what he looked like on Kingdom Hearts Birth by Sleep but he had no keyblade, a Nobody was left behind on theat day making who we know as Xemnas but we will get to him later Xehanorts Heartless called himself Ansem the name of his master. Now Xemnas he is the Leader of Organization XIII and has been planning to get Kingdom Hearts so they will be whole and have a heart.
Ventus' Story:
Ventus was a likable boy who had his two friends Terra and Aqua, and long ago before he lived at the Land of Departure with Terra, Aqua and Master Eraqus. He was with Master Xehanort and Xehanort wanted to try and make Ventus have his Darkness unleashed but Xehanort got impatient of Ventus' Failures so he forced the darkness out of Ventus creating Vanitas. Now Ventus Looks alot like Roxas as you can tell and Vanitas looks alot Like Sora, but on the battle with Ventus and Vanitas their hearts fuse so they are one Vanitas(Ventus heart fused)fights Aqua and Aqua defeats him then the little of that heart has mostly Ventus inside it, Ventus's heart fuses with Kid Sora's heart.
On Kingdom Hearts when Sora is turned into a Heartless the Nobody left behind looked like Ventus and on Kingdom Hearts II Sora looks like Vanitas (only that he has brown/blonde hair and blue eyes in stead of black hair and yellow eyes).
Aqua's Story:
Now Aqua is a kind young lady who know right from wrong and She was made into a Keybalde Master after the Mark of Mastery Test she followed Terra and Ventus to other worlds but after her battle with Terranort she found herself and Terranort falling into darkness she then uses her armour to save Terra/Xehanort and lets her self fall into the Darkness, she then meets Ansem...The real Ansem years later down there and he talks about a Keyblade wielding boy travelling to different world to save the light and destroy the darkness, Aqua mistake the boy to either be Terra or Ventus but then the scene changes to everyone sitting around somewhere shouting into the air "SORA!".
