Muta (SMU) is the Shattered Mirror version of Muta. He arrived in the BZPB Multiverse through the Shattered Mirror I, but crash-landed on an asteroid and stayed there, inactive. A few months later, when multiple beings arrived on the asteroid including Muta, Shockwave, Yon and Trantoshen, he was awoken and immediately started firing at the group. He engaged in a one-to-one battle with Muta, and revealed to him the shocking revelation that Muta stands for 'Multiple-Utility Tactical Automatron' and was built by the great engineer/scientist Jarvis. Angered and confused at this, Muta took their fight into space, where the brawl continued, until Ferox flew into them, demanding information on Jarvis too, having learned that Muta was built by him.
