What's Warworld about?

[JL4Ever]

I know I read what Warworld was about on Toonzone but I forgot. Can anybody fill me in? :(

Warworld is about when Mongul takes Supes to his planet (Warworld) to fight in Gladiator type games. We should see just how strong Superman really is in this episode.

[The Guard]

I'll bet it's based on the Warworld story from SUPERMAN: EXHILE.
