Wayne Tech and LexCorp are developing a new metal alloy called "Metallo" with the intention of revolutionizing the medical field. However, when Batman responds to a break-in at a LexCorp warehouse in Gotham by Metropolis' notorious Intergang (with John Corben and pre-Firefly Garfield Lynns) where the alloy is specifically targeted, he decides its time to pay the city of tomorrow a visit.
The Daily Planet has been investigating Lex Luthor as well, with Lois Lane and Clark Kent working to tie Intergang's funding and advanced weaponry to LexCorp.
Luthor bonds John Corben to with the experimental metal alloy to create Metallo as Metropolis' new superhero. To gain the city's trust, tragedies are orchestrated for Metallo to rescue citizens. In doing so, he also frames Superman & Batman, turning public opinion against them.
The two heroes must team together to defeat Metallo & Luthor, while clearing their name.
