Pretty Good for the most part
It was funny to a degree, though the comedic timing was kinda off and not all the jokes were very funny. The character seemed like a half assed maddox imitator but somehow the blandness didn't eliminate all my enjoyment of the flash. Yes as some said earlier, Sephiroth is usually portrayed as a really cool character, though this isn't the first flash I have seen making fun of him. I just thought that the way you made him out didn't show a very good understanding of what eccentricities would make him humorous. Despite doing a disservice to Final Fantasy and your flash by using him like that, stuff like a band called Glass Stomach and the random acts of childish violence Sephiroth commits were amusing.
