ok this is the reason there are plenty of theories online saying riku is xehanort by time travel. sora said to in kh1 that when we build this raft we might forget about our parents. also depending on the age of young xehanort whose probably younger than terra but he is tall as vanitus. riku is taller than sora and usually you can tell who is older by height. in a easy way of explain by looks.vanitus>ventus>sora>roxas as to xehanort>Terra>Riku.scientist xehanort has brown eyes riku has blue eyes even in his dark point form he still has blue eyes. Please don't take this the wrong way but xehanort is African or he is a mixed color. This might be wrong because I just started playing kh bbs and I have not finished yet but thanks for reading this. :smile:
