Game of Thrones and that Matthew McConaughey one (can not think of the name to save my life) are the best visually to me. I’m sure there are plenty more that look just as great. Jmo.
But let’s not forget the biggest and baddest dragon of them all, The King of Terror, King Ghidorah. This dragon is so big and bad, he has given the King of the Monsters, Godzilla, a run for his money.
