Zako is a mass-produced cat-type combat robot with black and white armor operated by Leon. As the name suggests, it's weak... It features cat-ear sensors and a glowing blue face display that shows expressions. Faithful to orders and judges situations mechanically, yet the display shows rich emotions. It gets teary-eyed when damaged, and its eyes become "XX" when taking severe hits. Its speech is mechanical and sometimes causes gag developments by interpreting orders too strictly. Often breaks down, slacks off to smoke, and frequently demands improvements in working conditions.
