Lucifer is the oldest of the seven brothers and is definitely the most dangerous and powerful one of them all. He is the most prideful, scary, sexy, and feared one of the seven demon brothers and even back in Heaven he was feared. Although he's a big scary demon who is Lord Diavolo's right hand man, he also has a soft side when he isn't dealing out punishments. He cares deeply about his brothers and their life where he wishes to protect them from anything that could bring them harm.
