this picture seems to be making fun of the fact that Ash has saved the world from many disasters that could´ve been caused by pokemon that are classified as dangerous or involved in dangerous circumstances.
I can't help but feel like this picture would be 100 times better if that was a Rayquaza instead of Pikachu. I mean it ALREADY looks like Rayquaza except for the ears. You'd also have that whole Metal Gear Ray...QUAZA thing going for it.
