The villain may be the most evil character in all existence, but has a certain sidekick love interest. Usually the love is one-sided, but can be two-sided as well. This can apply to a boy or girl sidekick, but usually is only found as a girl. She's usually small and pretty, someone you wouldn't think such a person could ever attract. Sometimes she is smart, a good fighter, neither, or both. If not careful, this character may easily become a Mary Sue. (If this already has a page, link me to it. I've searched many times.)
