Dr. Wily built the Wily Walker as a walking weapons platform with anti-personnel and anti-armor support and decay-resistant chemical weapons to gain sponsorship from the military. Although Wily claimed that he only wanted to show its versatility and that he would have removed the chemical weapons for its final checks, the use of those weapons got him sanctioned for unethical robotic experiments. Surprisingly, the Walker was neither seized nor destroyed by the military, and its chemical weapons were also never removed, though Wily's comments about its location being too dangerous to dismantle suggest it was left there to avoid worker fatalities than anything else.
