Battle takes place on a deserted area. No prep. BFR allowed.
Superman, Wonder Woman, Martian Manhunter, Flash, Green Lantern Hal, Aquaman, Batman vs.
Ant-Man, Hulk, Hercules, Black Panther, Hawkeye, Wonder Man, Vision
Speed flight and power gives the JLA the win here. Herc and Hulk are tanks but with the flight aspect they are stuck fighting the grounded units. Wonderman and Vision get taken out by Supes, Wonder Woman or Martian Manhunter. Supes Microscopic Vision, MM's TP or GLs ring can pick up and take out Ant Man. Bats can occupy BP or Hawkeye. Flashes speed can be lethal. Just way too much for the Avengers here
