Falling in Reverse once asked, "so why do good girls like bad guys?" The pop-punk band's question missed the mark by a little - people of all genders and qualities love bad boys - particularly when they're anime characters.
Some anime bad boys are relatively harmless, but give off an aura of danger and mystique - either that or they aren't mysterious at all, but use anger and aggression to hide their deeper insecurities. A few aren't even "bad" per se - they're just rockin' that wild aesthetic. Meanwhile, some of them are actually villainous - which is exactly what makes them so compelling. They're sexy, they don't play by the rules, and they're layered. Often, these characters have excellent motivations for their less-than-ideal behavior - but even when they don't, viewers still want to know what makes them tick.
