Really, other than the fact that one had a '80s contemporary dance style as a hobby, and the other sang professionally a musical style associated with a '70s contemporary dance style, they have also most nothing in common. I know they aren't the deepest characters ever created, but please don't simply label them "Dazzler = 1970s dance craze" / "Vibe = 1980s dance craze" and walk away. If you do that sort of thing, then you're not getting as much out of your comics as you deserve.
