Welcome to Kingdom Hearts Answers. What would you like to know?

It all depends on whether you choose to believe in me or not.

Plot details for the Kingdom Hearts series follow.

Nope. Xehanort in his younger years, and Terra just (coincidentally) look alike. Terra's body is just what was used to be the likeness of Ansem, Seeker of Darkness and Xemnas, but used Xehanort's heart, just using Terra's likeness. (Just to make sure the way I'm explaining it isn't confusing) The timeline for Xehanort is this: Young Xehanort (or just Xehanort) lived on Destiny Island, he eventually became a Keyblade Weilder, along with Eraqus, whom both worked up to becoming Keyblade Masters. Then the events of Birth By Sleep occur. Ect, ect.  Timelinesplitter Chaos 23:40, January 11, 2013 (UTC)
