Doctor Doom x Black Adam + Story

Black Doom Origins by MoonKnightFan101:
Adam Al'Mawt was born to a concubine and tyrant king of Ancient Egypt, although he never knew who his father was, as he was a slave in lower Egypt. Fleeing from his enslavement, after learning the truth about how his mother sacrificed her soul to gain magical powers to liberate her people from her evil tyrant ex-husband, Adam found a warm shelter to a priest. The same priest who taught her mother the magics and they taught Adam same Khemetic magicks and sciences he taught her ex-student. After several years of practise, Adam was ready to use his new found talent in liberating his people, so he killed his father and established himself as a king. Married to a lovely consort, Adam found comfort in her but when tyrant kings loyal men came to overthrone him, they ended up mortally injuring Adam killing his beautiful wife. Enraged and angered, Adam fled with his consorts lifeless body, and swore vengeance upon the killers, returning to the temple of the priest who taught him. Adam mumified himself and completed a spell which would turn his dead consorts body into magically enhanced armour. By encanting the first letters of his ancient gods as "SHAZAM!" the corpse of Adam's body formed around Adam into said armour. Following this, he attacked his fathers loyal minions with all of his might, returning to his throne as immortal king.
