The RX-178-X0 Prototype Gundam Mark II is a successor to the RX-78 Gundam created by the Titans. As a prototype, it's distinguished by the pursuit of performance without regard for cost, and its specifications can be described as monstrous for its time. In particular, it adopts new technologies like the movable frame and panoramic monitor which appeared in the Gundam Development Project, and aside from the strength of its armor, its capabilities are a match for those of the second-generation mobile suits which appear in the subsequent Gryps Conflict. Its armament include beam sabers and a beam rifle whose output rivals that of a Magellan class battleship's main cannon. But although its output is high, the beam rifle's accuracy is poor, and a limiter that cam constrain the output and a selector that can change the power according to the combat situation are added when the RX-178 Gundam Mark II is constructed during the later Gryps Conflict. In terms of overall performance, this machine boasts capabilities in the top class of the One Year War era, but shortcomings like its extremely short operating time and inferior ease of operation make it suitable for only a select few pilots. Its cost-performance ratio is also very poor, and it's said that a few Pegasus class warships could have been built in place of this one machine.
