you want to fade the background not the cartoon. Assuming the background is a layer and not the locked background (if it is, then you double-click on it to "float" it to a layer). Select the background layer, add a layer mask, make the layer mask a gradient from black to white as desired.
If you want the fade to follow the contour of the cartoon you can either add a white glow to simulate the fate or create a layer based selection from the cartoon's layer then switch to background layer, feather the selection and use it for the backgrounds layer mask.
