This is just so proposterous that I almost didn't justify it with a response. First of all, Lucifer was an archangel. In fact, he is one of only 3 archangels mentioned in the Bible. We learned in Hebrews 1:14 that angels are spirits and don't have earthly bodies. Therefore, how could he arm wrestle - he has no arms! Now, we do know that they can appear to humans and when they do, they take on a male appearance. That thing does not look like a man, but rather, a very threatening creature. Ergo, he has not taken on human form to have those arms. Second of all, when the other two archangels were described (Michael and Gabriel), they were described as very handsome. I don't know a woman one who would honestly call that thing attractive. This is just ridiculous.
