I, Dr. Mikeneko, received a message from my brother, Kuroneko. It's time for the Mikeneko family to make a name for itself in the world. The first battle was when Chacha and her friends came to my laboratory. I got mad when they broke my inventions, and the activation mecha Nyandabar Z. They broke my tracking cat-shaped missile, and I was defeated by her Magical Shoot. That was a regrettable defeat due to a trivial accident and an accidental run-in. But its special 5 Nyanja missiles failed, and it was once again defeated by Magical Shoot. I launched my Great Nyandabar and was confident that I had defeated Chacha, who couldn't transform, but it was too heavy, and neither the Great Neko Hand Bomber nor the missiles worked. The communication device seems to be malfunctioning a bit, but there's no time to fix it. The ultimate final touch, the Mobile Mecha Nyandabar WXYZ is launched. I'll fix the communication device later.
