Akhenaten is the villain of the comic miniseries Marvel: The End by Jim Starlin.
He was a Pharaoh who was chosen by the Celestial Order to be empowered with powers surpassing those of many cosmic entities - he was meant to use this power to recruit others for the Celestial Order (in a similiar manner to a Herald).
Instead he decided to use his newfound godhood to destroy all the gods and heroes of Earth in order to rule it as a supreme being, in such that even the asbracts such as Eternity and Infinity could not do anything against him.
Ironically it was Thanos who would come to Earth's aid and through the use of the Heart of The Universe easily defeated Akhenaten.
Powers and abilities
The Heart of the Universe gave Akhenaten Vast cosmic power to manipulate energy, matter and reality, pierce dimensional barriers, make large groups of heroes disappear with a nod, near omniscence and superhuman senses.
