PLEASE READ: Okay, this is probably a lot of over-explaining, but just to get the jest: This is the part where Riku gets possessed by Ansem in KH1, so that's why his voice is italicized (he has the weird possessive double-voice thing…) and that's why he's called 'Riku-Ansem'.
Disclaimers: Don't own Kingdom Hearts, and alas, I never will! (Hehe, I've always wanted to use that word, 'alas'.)
Riku-Ansem chuckled to himself as he exited from another dark portal and into the Grand Hall of Maleficent's castle. "Fools!" he cackled wickedly. "Soon they shall suffer the wrath of over-consuming darkness, and I, Ansem, Seeker of Darkness, shall consume all light and bath in the everlasting darkness of Kingdom Hearts!" He threw back his head and laughed. "Now to find that old hag…"
"Hi Riku!" Sora chirped, bounding over to his best friend. "Whatcha doing?"
Riku-Ansem screamed in terror, jumping out from his desolate, dark corner. "Uh...h-hello, little boy!" he mumbled nervously. "Sorry, no time to talk…" He began to slink away, hoping Sora would take the hint. He had to go find Maleficent.
Sora, however, didn't notice. "Have you seen Kairi anywhere?" he asked, taking a gander (ANOTHER word I've always wanted to use!) at Hollow Bastion's dreary décor.
"No, I haven't seen the girl anywhere!" Riku-Ansem gave a panicked cry, discreetly shoving the half-dead island chick behind him down the stairs with his foot. He tried leaving again, hoping that Sora wouldn't ask about the Princesses in jars, or about the giant heart-shaped portal of darkness, or about the man skirt. However...
Sora gasped and narrowed his eyes. "Riku?" he asked, cocking his head to the side. "What's wrong with your voice?"
Riku-Ansem froze in his tracks and began to silently curse himself for not fixing the voice. "T-The voice?" he stammered, struggling to raise his voice up a few octaves. "There's nothing wrong with my voice…"
Sora shook his head. "Yeah there is; it sounds all eerie and spooky and stuff!" The young Keyblade wielder grinned.
"I…well, this is very hard for me to say…but…I'm…p-p-p—"
"Pubescent?"
"YES—wait, no…YES! That's exactly it!" Riku-Ansem took a long exhale of relief. "(I was going to say 'possessed', but…) Yes! My testosterone levels are raging, of course!"
Sora hung his head. "Aww…I wish my voice would do that…"
Donald Duck began glaring at Riku-Ansem and tapping his foot suspiciously. "Hey, I thought your voice wasn't supposed to do that until KH: Re: Chain of Me—" He was cut off by a summoned falling Large Body Hearless.
Sora finally shrugged. "Well then, just as long as you don't start going all 'emo' on me, I guess I'll leave you alone!" he sang, scampering off to go find Kairi again.
Riku-Ansem lightly chuckled and waved the boy goodbye. "Oh, don't you worry!" he called, breathing out another sigh of relief. BUT LITTLE DID HE KNOW.
Thus, Riku's bishonen-emotional period began! I doubt Ansem even knows a thing about teenage male puberty…
