In the prototype, if Web-Bat drops down, any webs on the screen will flash like he does. In the final version, the webs will not flash. The webs don't cling on to Joe and make him move slower if they hit him in the prototype, whilst in the final, they do.

Web-Bat's second form is colored very much like Adam West Batman in the prototype. For the final they changed most of his colors. You cannot kill the bats with shuriken in the prototype, as they just bounce of them. In the final this was changed so it is possible to kill them with shuriken. In the prototype, Batman takes less hits to kill, doesn't change color when hit, and his death sequence is a lot shorter than in the final version.
