Prometheus Vs Batman

Prometheus

VS

Batman

Read JLA #16 and 17.

After already taking out Steel, MM, Zauriel, and The Huntress

Prometheus whooped batman's butt. He uploaded Batman + 29 other great fighters' fighting techniques in his helmet and downloaded them into his brain.

Then proceded to kick the rest of the JLA's butt until he met Catwoman.

When he met Catwoman, he got whipped.

And then Batman kicked his ass in World War III. He would just do the same thing he did the last time.

Although Prom. may have updated his helmet.
