The theory is this:
Axel, before he was named, had to have given Xemnas a fake name to cover the identity of his Somebody. I don't have the time to type out 20+ pages of a manifesto that my friend put together regarding Axel and his supposed Somebody, but the argument is that Axel and Riku are Somebody/Nobody.
Guys and girls, hear me out.
If any of you recall, Riku wanted to protect his identity from those he cared for so that they wouldn't learn of his life in darkness; he wore the blindfold, the Organization cloak and very well could have gone by a codename prior to having Ansem's appearance and thereby taking his name. You want information? You've got it.
I thought the reason why Riku wore the blindfold was to make him forget he had sunken into the darkness. Forced to take on the appearance of the one who had caused so much pain to his friends, he could do nothing but lie to himself and prevent himself from seeing his appearance.
Points continued:
-Riku was clearly
infatuated with Kairi and displayed acts of chivalry greater than Sora could have
ever done in all three games together.
-Axel, while less heroic and passionate in his protective actions, saves Namine in Castle Oblivion and in KHII at least four times--freeing her from Marluxia, freeing her from a locked closet, taking care of her while she isn't with Riku, granting her wish to see Kairi. Similarly, in KHII, rather than harming Kairi as he kidnaps her, he merely takes her arm and pulls her into darkness with
no intentions of using force. Why does he open a portal for Sora to go through in Betwixt and Between? For Kairi and Sora's benefit. Call it a way to "make up" for, not only trying to harm Roxas, but for putting Kairi and Sora in harms way. A very Riku-esque thing to do.
Riku was never infatuated with Kairi. Ever. Sure, her sudden appearance out of nowhere clearly intrigued him as much it did Sora, but he never was infatuated with her. That was Sora's thing. And Riku, being Sora's best friend and brother-figure, noticed this and picked on Sora by pretending to like Kairi. Of course, him being Sora's friend and Kairi being the most precious person to Sora
besides himself, Riku felt obligated to protect Kairi when Sora was incapable of it.
Axel saved them for his own profit. He didn't care if Kairi and Namine joined again, this just meant he had a chance to see Roxas one more time, HIS best friend. Why Axel doesn't use force when kidnapping her in Twilight Town is most likely because Kairi couldn't fight back. And neither could Pence or Hayner. Olette just sat on the couch and watched them. >>; Anyways, Axel shows up and grabs her arm and is able to drag her into the portal with little resistance, being that much stronger than Kairi.
-Riku and Axel's eye color are unique to them and
only them. Aqua; not green, folks.
-Stature, posture, gesticulation, even hair style (given that Axel's hair be watered down some): all very similar
Just as Riku wanted to hide himself from the world after throwing himself into darkness, Axel would want to protect Riku's true identity, and thus give Xemnas a fake name to re-create.
Those are the more important points to the manifesto, and why I say Axel is most
definitely NOT "Ale" because he's "hahaha. BEER." And his relation to Reno? Don't even get me started.
Have anything you'd like to add in objection, fandom?
Eye colors don't match up. And besides that, using eye color as a basis isn't a very strong point in the first place. True, Nami, Kairi, Sora, and Roxas all had blue eyes, but then again, so did half of everyone else. =P
Axel is taller than Riku. Riku was a few inches taller than Roxas and Axel is clearly a foot taller than Roxas. Don't believe me?
Sorry if that stretches the page.
You can see how much taller Axel is than Roxas and I'm pretty sure that Riku was only as tall as him or taller was when he had Ansem/Xehanort's appearance.
Their body types aren't that similar to me. Axel looks skinner than Riku and Riku looks more muscular to me.
Now, about your point on the hair color, when a Nobody is made, their physical features are similar to their other yet not identical. Although Xemnas' hair still retained the same color it was as Ansem, Roxas' hair was blonde as opposed to Sora's brown. However, this does not mean that Riku's silver/gray hair will turn into the bright red known as Axel's hair.
The last thing I have to add is that Axel is clearly an adult while Riku is still in his teens. True, we have no proof yet of Nobodies aging other than Namine, but even if they could, that would not explain why Axel is older than Riku.
Point is: Axel =/= Riku.
