The famous and widespread image of a pharaoh is that of Ramses II. Ramses II is a New Kingdom Pharaoh, whereas Narmer was an Old Kingdom Pharaoh. In between that there was a Middle Kingdom.
Ramses II ruled from 1279 to 1213 BCE which was about a thousand years after Pharaoh Narmer.
The continuity of Egyptian history and the continuity of Egyptian government and the structure of the society were important under the Pharaoh.
Ramses a New Kingdom Pharaoh was largely remembered because he led an enormous building campaign. He built temples and statues of himself all over Egypt. He obviously had a lot of resources to do this and the kingdom must have been prosperous at the time.
Over half the surviving temples in Egypt date from the reign of Ramses, so there are a lot of statues of Ramses. Ramses reigned for a very long time and lived to be almost 100 years old, it is said. He had many, many children. He became a super human father god figure living longer than normal people lived and certainly longer than ancient Egyptians lived.
He had many children with numerous wives than ordinary men would have and so on.
There is a statue of Ramses II from the Temple Complex at Luxor, and it is larger than life size.
The representation of Ramses is not all that different than the representation of Narmer. Narmer was represented wearing a crown that symbolized Upper and Lower Egypt joined. He had the beard that represented his status as Pharaoh.
