Xehanort's didn't have bangs over his forehead.
I'm pretty sure Terra's features are similar to Xehanort. And since we don't have much info on Xehanort's appearance, you can actually use XH's. He kept his exact same form. Albeit, his skin color is darker.
That's not Xehanort, that's Ansem, seeker of goddamned darkness. Completely different people.
That's like putting up a picture of Roxas and going, "See? That's Sora!"
This is what he looks like: (noticeably with two bangs, and if we're looking to use his different forms, Xemnas has even more bangs.)

Is the build good enough for you? Also, all those organization Somebodies are about ten years younger than their Nobody counterparts. Terra looks to be about 20, not around 14 or 15 (Vantas' likely age because it's Sora and Riku's ages in KH1). Xehanort is confirmed to be about 30 when he gets to AtW, no?
Terra is not twenty. I don't know how old he is and I can't be arsed to check, but Terra is in his teens.
Riku in KH2 is FIFTEEN. I'm fifteen and I'm barely half his size. Height/bulkyness means nothing about age in Nomuraland, or, well, they do, but it's realistic and two people of the same age can be taller/bigger than others.
Anyway, when Xehanort was found, EVEN if you're saying Terra is twenty now, he'd only be twenty one, because it's one year after BbS.
Therefore, no, Terra->Xehanort does NOT make any more sense than Vanitas->Xehanort.
Stop acting like you are the the all mighty person who decides what is common sense.
Excuse me while I lol. I was going to respond to that and explain it, but then I just backspaced away because clearly I can't be arsed to argue over this with you. I'm just trying to be nice here.
That doesn't mean much to me. Sure people can have a habit, and that would fit nicely. But logically, that doesn't mean anything to me.
Yet the fact that Terra/Xehanort have a common hairstyle that a lot of Japanese characters have does mean something to you? Or that his eyes are yellow? Vanitas' eyes are yellow, too. Now what? Does that mean I have a good theory? No, it doesnt. Terra->Xehanort isnt anymore logical than this.
Edit: Oh wait, yeah I see what your saying now. And I guess Sora's face was made to look more like Ven's in KH2. Like how his hair became more blondish.
Anyway, I still doubt Vanitas influenced Sora's look.
I doubt Sora's face was made to look more like Ven's in KH2, because in KH2 Ven probably wasnt thought of yet.
But, anyway, if Vanitas is a Ven replica then yeah. But I'm not saying he influenced his looks.
Hell, I'm not saying anything, really.
I'm just saying you should stop denying things and labeling them as illogical and then going back to believing your other not-any-less-illogical theories.
