The Last Alien Pharaoh?

While Akhenaten is well-known because of the mysterious shape of his head, the list of characteristics is lengthy: an elongated skull, long neck, sunken eyes, thick thighs, long fingers, backward-turned knee joints, a prominent belly that suggests pregnancy and female-like breasts.

 
The first thing that is strange is his elongated skull, and in all of the statues and depictions of him, we see this elongated skull. In general, his body was sort of like a feminine and masculine mixture. This was, in fact, strange since all other Pharaohs were depicted as strong, imposing figures. Akhenaten however, was not depicted like that, but as a weak, strange looking being with an extremely elongated head.
 
Why would Akhenaten order the changes he did in the royal iconography to show him as this “weak” Pharaoh? Mysteriously, Akhenaten’s wife Nefertiti was also depicted having an elongated skull. Did they have some genetic anomaly that caused their heads– and body is in general to be misshaped and disproportional? Alternatively, is there something more to this strange Pharaoh and his origins? Is it possible that he was a hybrid human being? With genes and DNA from Extraterrestrials?
