There's a reason why (stupid) people argue Kefka is better than Sephiroth and vice verse instead'a Lightning is better than Cloud 'n such: in many works, it's all 'bout the villains. Some less complex stories almost entirely rely on interestin' villains to keep ya interested. While the Smash roster has always had a skewed hero-villain ratio, I don't agree with it in any way. Many Ninty villains are just as iconic, if not moreso, than their series' hero counterpart.
rhetorical lawl go ahead anyways if ya want
That's only 'cause happy endings are the mainstay in media overall when you've got clear cut heroes and villains derpin' it out. And even then, legends never die. Includin' if that legend was a horrific story of some megalomaniac's life. Hitler is long-since dead, yet nutjobs 'round the world still swear fealty t' that madman's legacy and fascist agenda.
