The flagship of Char Aznable's Newborn Neo Zeon, it was developed based on the former Principality of Zeon's flagship, the Gwazine-class. Char commandeered his fleet from this ship and so it was installed with a living room for his use. Like the Londo Bell's Ra Cailum-class, the Rewloola-class has excellent anti-ship firepower and mobile suit deployment capabilities. The ship has two launch catapults, one above and another below its bow. These launch decks could additionally serve as recovery decks - and both launch bays are connected to a large internal maintenance bay. The ship is also equipped with twelve thermonuclear thrusters and made use of two large cooling fins along the hull at its midsection to maximize the ship's ability to irradiate heat from its incredibly high engine output. Additionally, the ship seem to have long-range cruising ability as it is equipped with twelve propellent tanks.
At the end of the Gryps Conflict, Char Aznable disappeared, and was presumed dead; however, in UC 0093 he re-emerged with a self-made declaration that he was now in command of his own Neo Zeon movement.
