How I Would Have Written Batman v Superman
After turning Green Kryptonite red, Lex Luthor sets a trap to poison Superman with it, causing him to act out in strangely aggressive ways. Forensic scientist Barry Allen from Central City is brought in by Silas Stone in Metropolis to figure out what's going on. While working late, a bolt of lightning strikes Allen, turning him into Flash. Riddler kidnaps Martha Kent and frames Batman, hoping Superman will kill him in this state. However, Lex secretly allows Batman to steal Green Kryptonite from him, knowing he'll kill Superman if absolutely necessary. Martian Manhunter tries to help, but Superman nearly kills him. Batman steps in with Krytonite weapons to hold off Superman. Barry Allen's STAR Labs team finishes an antidote and Barry races it it Batman. Then Batman confronts the Riddler and Lex attacks Superman in his warsuit. However, Lex is seen as the hero who tried to take down the rogue Superman. Unable to defend himself in court, he's put in a Red Sun cell.End credits: Someone reports to Dr. Stone that his son has been in an accident
