An improved version of the MYU robot fought during the Battle of Destiny, this is the last boss you will fight in the True End routes prior to the final battle, and its appropriately as tough as it would seem from that fact alone: its stats beat the ones of its original version by far, and to make matters worse, it has the best properties of the pre-Mode Shift and post-Mode Shift MYU without any of its weaknesses. In other words, it has a monstrous resistance to both Song Magic and physical attacks, as well as high resistance to all elements excepting Wind, so if you're playing in Hard, most likely using the Ultra Supermoves for all your Vanguards and high-charged Flipsphere won't be enough to destroy it, and you'll have to repeat the procedure to finally kill it off.
