A/N: This is indeed Xigbar/Saix, but is not intended as a couple. It's more of a "hate" thing rather than "sexual tension" or anything.
Don't own the rights to Kingdom Hearts, unfortunately.
Xigbar loved being second-in-command; it gave him a sense of superiority. He just happened to be a generally devious person, immature too, and thus it seemed that he was not suited for the position.
He was proud to be who he was. He was proud to be Xigbar, second-most-powerful non-existent being ever!
Saïx, however, took that away from him. When Saïx came into the Organization, Xigbar instantly felt that confidence challenged.
Xemnas immediately took a liking to this new member, took him in like a lost puppy in the rain.
Xigbar passed Saïx in the hallway. Xigbar's golden eyes met Saïx's wild equally golden eyes. Their eyes narrowed and darkened.
"Suck up."
"You're just jealous."
"Bastard."
"I'm not sinking down to your pitiful level, you do realize I assume? As second-in-command, you should realize things like that."
"Shouldn't you be off licking Xemnas' boots or somethin'?"
Saïx's eyes narrowed even further; only a sliver of his pupils could be seen now. "Shouldn't you? You're the one who needs to earn his respect."
"Look, you fucktard," Xigbar snapped as he grabbed Saïx's collar. "I'm second-in-command here. Don't know what Xemnas has got you thinkin' but you're not one of 'us.' You're not one of the original six. You haven't known Xemnas for TWO LIVES."
Saïx's eyes glowed ominously. "Put me down, at this instant," he threatened. His hair began to stand on end, and the X-shaped scar on his head began to grow. Xigbar reluctantly let the younger Nobody down, but not before muttering, "I'm not afraid of you, you son of a bitch."
Saïx gave Xigbar one last venomous glare before walking casually in the other direction.
"Likewise, you fucking newbie."
Oh em gee, what a shitty ending! -you proceed to shoot me- That's why I have a rather humerous epilogue to make up for it. Click the 'next chapter' button if you want to read it.
