Dario Melek was a male combatant who held the title of champion for Ney Madiine on Hesperys Station. In the year 382 BBY, he engaged in combat with the Jedi Knight Gella Nattai at a location known as the Rusty Rancor. His attire for these encounters included green velvet robes, and he was known for using a green double-bladed lightsaber.
By the time it was 382 BBY, Melek had become the fighting champion for Ney Madiine at the Rusty Rancor, accumulating ninety-nine victories in the arena.
Melek was present when Axel Greylark and the Jedi Knight Gella Nattai arrived at the establishment seeking information, which resulted in him being pitted against Nattai in a fight. Upon his introduction, Melek sent a kiss towards the spectators. He confidently initiated the attack on Nattai, and the two exchanged blows. Melek displayed fear when Nattai used her Force abilities to disarm him of his lightsaber. In a desperate attempt to secure his hundredth victory, he resorted to tackling Nattai. Aware that Madiine disapproved of interruptions, he conceded. The Jedi returned his lightsaber and advised him to defend himself from the approaching guards, but the floor beneath them gave way, bringing the fight to an abrupt end.
Dario Melek made an appearance in Convergence, a novel published in 2022 by the author Zoraida Córdova as part of the Star Wars: The High Republic multimedia project's Phase II.
