Marvel has created most of the Godly pantheons, the most known atleast, they created the norse pantheon with his highest leader Odin, the greek pantheon with his highest leader Zeus, the Japanese pantheon with his highest leader Izanagi, but they created the egyptian pantheon without the highest leader. i mean Odin was the king in norse mythology, Zeus was the king in greek mythology...etc, but the king in egyptian mythology isn't Osiris or Horus as they are referring in comics, the real king is Ra.
i think Marvel writers are missing a lot, maybe they have little knowlege of egyptian myths, but creating a story about Ra and his fight against Apophis and including the main super heroes in this story will be really amazing!!! they are really missing good opportunities here.
instead of bringing the real Ra as interpreted in Mythologies, they created a lame character called Atum Demogorge and they made him the first father of egyptian pantheon. that was really lame.
