First and foremost, my priority is to protect the city and its residents from any harm the giant robot may cause. I would begin by using my abilities to quickly relocate innocent civilians from the danger zone. Next, I would closely observe the robot's behavior and capabilities to identify its weaknesses and determine an effective strategy to neutralize it. If possible, I would attempt to communicate with the robot or its controller to ascertain its intentions and find a non-violent resolution. However, if the threat persists or escalates, I would use my superpowers to disarm, disable, or destroy the robot as needed. Once the threat is neutralized, I would work with local authorities to investigate the robot's origin and help prevent similar incidents in the future.
As a powerful superhero, you have been summoned by the mayor of your city to address a hostile giant robot, threatening the city's safety. Explain your approach to handle the situation.
