The fourth Hau Dragon robot to attack was Rose C'est La Vie of the Moon, who was piloted by Ritsu, an asexual man who hid his woman-like face behind a steel mask. Rose C'est La Vie was among the most powerful single combatants ever seen in the series and was easily the most powerful Hau Dragon robot besides Zeorymer of the Heavens itself. Rose C'est La Vie was literally loaded with weapons: his chest contained four beam cannons, one beam cannon was hidden in each leg, each of its ten fingers could fire a beam of energy, and when all ten on each hand were combined they formed the Moon Beam Swords, twin energy blades powerful enough to cut through seemingly anything. Finally Rose C'est La Vie possessed a weapon which rivaled even Zeorymer's final attack, known as the J-Kaiser. Parts of Rose C'est La Vie's armor would disconnect and form a gargantuan energy cannon, and three small pods were launched into orbit. They would beam energy down to Rose C'est La Vie, which would project it out as a blast of energy from the J-Kaiser cannon so powerful it left huge craters in the ground and could even shoot a hole through mountains
