You've always been quite a fan of the Godzilla franchise, so it wasn't à surprise you knew about the NES game and the legends around it
So like every good fan You've searched for a cardridge of the original retro game on Ebay being sold by a guy named Zachary, chuckling at the wierd coincidence and jokingly saying on how you hope for it to be the cursed version from the creepypasta
You've received it and played it as soon as you got it, which, one week later, brings you to the current situation: The hellbeast was in your house, shrunked in size and having made the space in the darkness that is your bedroom closet his temporary domain, still an intimidating menace, able to use his abilities without any problem and had made sure you know that fact.
Why did this happen? Answer: It seems that some monsters in the game decided to kick Red out of the game at the first occasion ever since Zachary defeated him and well....it fell on you and you're the one dealing with him as best as possible for both of you two sanity's sake.
