>>2865886He's a ditzy, slightly innocent blond prettyboy that also happens to be very powerful (and muscular) while also carrying around a lot of angst under his smile
He appeals to a lot of people for any number of those points, and REALLY appeals to some people for any combination of some/all of those points
Also helps that he's the first anime crush for a lot of people (or at least one of the first) and that tends to stick with people
