There could be no other choice for me except for the king of monsters, Godzilla. As a child, I was obsessed and in love with him, the noise he made the monsters he fought was all just so amazing to me as a kid. It was also a fond memory I had with my father as once a year we would stay up all night watching the movies. It also so happens that one of my favorite songs is about him.
Over the years Godzilla has changed drastically, started out as nothing than a guy in a suit to being a huge computer-rendered beast but he has always been my favorite and will continue to be so. Best wishes and may the gaming gods bring you glory.
