The premise for this scene is a movie in which Superman goes evil, again. To refresh the memory of some readers, in the comics, when Superman turned evil, he gave some kryptonite to Batman in case it happened again. This scene would be within a movie in which he did turn evil, and Batman got wind of it. Before Superman could come to him, Batman has time to make several items. Kryptonite bullets, and a kryptonite spary. The bullet's are loaded into the guns on the Batmobile, the spray is sprayed all over the Batmobile, so Superman can't come too near.

And now: I'm not crazy

"What on Earth is wrong with you? don't you remember your past, your purpose?"
"I have a new purpose. Destroy. I am gifted, until now, I have used my gift to service others. Now I will serve myself. The first step to that is: eliminate the competition."
With those words, Superman springs at Batman. Batman, moveing hardly anywhere near the speed Superman is dives for the Batmobile, just as Superman is about to reach him, Batman enters the area close enough to the Batmobile that Superman has to stop. The blast of air from such a sudden stop sends Batman blasting into his car. The Batmobile spins, and opens fire. Superman flys out of the way, the bullets missing by metres. The Batmobile rockets forward, the back jets on, he strikes at Superman. Superman flys away, easily outpaceing the Batmobile. The wings shoot out the sides, and Batman takes off. Superman flys straight at a corner, suddenly spinning with it out of the Batmobiles track. The Batmobiles bottoms jet brakes kick in as it takes a quick corner, metal screaches as the Batmobile turns totally vertical, seering straight at Superman, guns blaseing. Superman doesn't expect manueverability, and is caught of gaurd. He avades the shots fired at him, but one bullet comes close, the effect weakens Superman for a breif moment, which is enough. All weapons fire on the Batmobile. even in his weakened state, Superman manages to dodge the kryptonite bullets, but one other makes it into his arm. What with the kryptonite all around, The bullets peirces Supermans skin. He freezes, and looks down at his arm. It's bleeding. He looks up a look of pure hatred in his eyes.
"Now you're dead. I don't care if I can't get near you, I'll tear you apart. Arrgh!!"
As he shouts, he grabs two cars and hurls them at The Batmobile. Batman drives out of the way. Then using pure force Superman begins flinging cars at the Batmobile from all directions. Batman drives, Blasting forward with his jets roaring...

That was: unfinished? yes, 'tis to be continued.
