American Comics Agency: Starting with rescuing Iron Man

In a certain office in Hell's Kitchen, a blue-and-white cat is chasing a brown mouse, and on the boss's chair, a man is holding a cigarette and reading a newspaper. Next to him stands a man dressed in black. The tights have an inverted triangle on the chest, and inside is a man with a capital S.At this time, the man sitting on the boss's chair slowly took down the newspaper, showed an evil smile and said: "Welcome to my office, there are no commissions that we can't complete here, only commissions that you can't think of."
