Displaying broken sprites?

Question

I am completely new to the world of 2D engines. I figured out how to upload images and display them as sprites and stuff, but there is one question that bothers me. For example, when a "rocket" hits an object, it deals damage to it and leaves the crater behind. I would like the crater to show at this facility. This will require skipping some pixels of this image when rendering, right? My question is: how would you do this? What information would you use to save this? How to display a "broken" sprite?

            var data = new Color[t.Height * t.Width];
            for (int y = 0; y < t.Height; y++)
                for (int x = 0; x < t.Width; x++)
                {
                    data[x + (y * t.Width)] = perPixel(x, y);
