Dagan was a renegade priest from a nameless alien world. He discovered that an alien Mygorg named Sookaroth owned an eighteen-year-old slave girl named Starfire, whom he intended on making his concubine. Dagan rescued Starfire from Sookaroth's clutches and taught her a word she had never heard before – freedom. Dagan spent the next several months teaching Starfire hand-to-hand combat techniques and rudimentary weapons skills. Through Dagan, Starfire began to develop a sense of self-worth and independence. Before long, the two slowly began to fall in love. Some time later, Sookaroth sent his Mygorg soldiers to track the priest and escaped slave down. Starfire escaped, but the soldiers captured Dagan and brought him back to the camp where he was slowly tortured to death. The loss of her lover galvanized Starfire's will, and she swore an oath to free all human slaves from the clutches of her former captors.

- This version of Dagan (Earth-One), including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985-86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse, saving all the alternate realities, though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
