Yes yes, I hate Sephiroth for no real reason. I'm sure the moderator of the FF7 fansite is in no way biased in this assertion

1. Strawman. I stated 'beyond the reasonable standard' There are plenty of reasonable ways to hate on the man, but kvetching about their changing where his wing is isn't exactly one of them. This is why I responded with the equally laughable 'I don't like Kefka he's just the Joker' comment. He was the OWA in the original game. It was an indication both of power and of his flaw. It became ingrained as part of his image all the way back then.
2. Glass houses and stones. Especially since I'm hardly a Sephiroth fanboy.
Answer me this then - what does the wing actually do? KH and Dissidia are alternate continuities, they don't count.
It's the OG's Sephiroth in Dissidia.
In its sole canon Compilation appearance in AC/C, what does the wing do, what purpose does it serve besides looking cool?
It doesn't actually need to 'Do' anything. It might solely exist to show that yes, he's a monster, that Jenova is a part of his being. It might also act as a Spirit energy booster of some sort.
But they don't give us that, as I said in the CC Ultimania, they say in-universe they aren't really sure where the wings came from.
But we can draw some reasonable conclusions, given the only people in canon who have the wings are the three people with Jenova's genetic data in them from birth, and the folks they retrovirus into sharing their DNA.
Jenova can shape shift. She's been sealed away for 2000 years. Hell, it might just be that the wings are the only thing that Sephiroth and others with the fragmented DNA can shift into besides their normal forms, leading to He of the Wingbutt.
Considering AC/C has him sprout it for his final assault on Cloud, I'd take that as well, ties into my thing above. But I can't buy an explanation they don't officially provide.
Why not? I mean, you can't say 'yes this is the reason' but it does work as an explanation.
Also, 'It looks cool' and 'Rule of Cool' aren't completely analogous.
