This gigantic mecha is controlled by Shishi Red in his new form, Shishi Red Orion! As what was previously reported, Shishi Red transforms into Shishi Red Orion thanks to the power of Saikyo Kyutama, a Kyutama that channels the power of the original 9 Kyurangers. It is unknown if the other Kyurangers can also control this mecha as other Kyurangers can also use the power of the Saikyo Kyutama.
