maybe xion is actually an experiment gone bad by vexen,
when he tried to take the rock pokemon: Onix
and spliced its genes with Aqua who is
secretly Kairi (w/a new hair cut) who traveled back in time
to make sure terra never became xehanort.
but was unsuccessful because she died
from losing the will to live
soon after giving birth to her twin boys
sora and riku, whom she had with
terra, who was seduced by the dark side of the force
and joined MX as his new apprentice,
only to lose in a keyblade duel against
ven inside a volcano which then
errupted and spat him out ,
causing him to land in radiant garden
with no memory of it all,
including his arms and legs missing and
his body burnt, resulting in him
having to rely on wearing auto-mail
for the rest of his life, until
he decides to become a state-alchemist
and begins a journey in search of
the philosopher's stone
so that he can get his original body back.
on his journey he faces against homunclulus
*cough* nobodies who are also searching for
the philosopher's stone so that they can be
complete humans again,
unfortunately no one will
ever get the stone because after hairy potter
fight's voldermort in the first harry potter movie,
dumbledore has the stone destroyed. :?
PS. i'm just kidding, i don't honestly think this
don't take it so serious
