Darkness and Light hold everything together and Time and Space are the guardian forces
that watch over the whole universe. Both Time and Space have no weaknesses, since they are
far beyond everyones understanding. Even Luxord and Xigbar did not now exactly where their
powers come from, and even if it doesn't look like that, the powers of Time and Space are
FAR more superior than they could ever imagine ^^
If someone could use the powers of Time and Space, they would be impossible to defeat,
as you mentioned earlier!
Thanks for the comment and for the opportunity to talk to someone about the topic!
