... it even says "At that moment, the Temple dome shattered, and Dagon stepped inside to menace Martin. But Martin shattered the Amulet of Kings, and in a great burst of flame, the Dragonfires transformed him into a great flaming dragon: the Avatar of Akatosh. In the Temple of the One, the dragon and Daedra Lord struggled, Aedra versus Daedra, until at last the dragon cast Dagon back into Oblivion" so im gonna go with it being akatosh..... lol
