I've seen much better.
There wasn't too much redeeming about this flash. Your jokes were old and none of them was really any funny. If you could manage it you don't need every ending to be a friendship or a fatality and the audio should reflect that. You also might want to cut out the "Friendship? Again" line as it's never really worked in these types of flashes.
This couldn't have required too much effort. All you had to do was add layers. It would have taken time, but not effort.
You shouldn't mix your sprites. Where did you get the Marvel ones?
