The Madniks are a bunch of criminals who wear face paint and multicolor costumes. When Batman is shown fighting the Madniks, Booster Gold learns that they once fought Blue Beetle. Booster Gold goes back in time where he ends up helping Blue Beetle fighting the Madniks when they break into S.T.A.R. Labs to steal the Quark Pistol. When Booster Gold shoots the Quark Pistol, it ends up knocking them out. When Booster Gold returns to the present, he finds Batman fighting an energy monster and Batman figures out that Booster Gold was behind this. When Batman and Booster Gold end up transporting back in time to see Blue Beetle, they end up going to Hub City Penitentiary where the escape of the Madniks causes them to turn into Energy Monsters that drained energy from the electric fence. Batman, Blue Beetle, and Booster Gold end up pursuing the Madnik Energy Monsters to Hub City's Nuclear Plant. Batman and Booster Gold managed to reverse the polarity of the Nuclear Plant in order to return the Madniks back to normal.
