Okay, that was a mediocre flash animation. Your idea is amazingly trite, and I would prefer you drew your own work. Perhaps if you created an interactive movie, letting the viewer choose which two characters will battle, or three, if you really do a lot of work. Animate all the combinations of fights, and let us decide.
Otherwise, nice job, just try to improve the fluidity of some of the animations, and add more detail to what you create.
