Fingolfin was so badass that he forced the master of evil himself to fight him by shaming and shit talking. Morgoth's minions were like "are you going to let this guy talk you like this?" and Melkor was like "Ah shit, I really don't want to do it, but if I don't my homies are going to think I am wussy." The battle itself was so fierce that despite Melkor cracking the earth open with each blow he couldn't hit the bastard before he got a grevious wound to the leg. Even in death Fingolfin got the last laugh as Morgoth had a lasting reminder of why he was limping for the rest of his life. Peace!
