The Riddler goes on the air with his new show, Riddle Me This. As his henchmen introduce him, the Riddler introduces his first contestant, Booster Gold. Booster Gold is tied to a booth as is his robotic sidekick Skeets, while Batman is strapped to a giant electrified question mark. Each riddle that Booster Gold misses, Batman gets a zap. Booster misses the first riddle and Batman gets a shock. However, he uses a remote-controlled laser to cut himself free while Booster continues to miss his riddles. Finally the Riddler gives the final riddle. Booster is unable to solve it and the Riddler activates the killing shock… only to discover that Batman has escaped. Batman frees Booster and the Riddler's henchmen move in. They don't last long, and the Riddler takes a final swing at Batman only to go down as the Caped Crusader delivers a final riddle.
At a nuclear reactor, Professor Stein is giving a tour to students and their coach, Ronnie Raymond. One of the students, Jason Rausch, objects when Ronnie keeps interrupting. Meanwhile, a costumed scientist, Dr. Double X, slips into the reactor room. Batman arrives to thwart him and demands to know where his energy duplicate is. X's duplicate attacks Batman from behind, knocking him out, and tells his physical half to complete their plan.
Raymond tells Jason that they just need to get through the tour and then they never have to see each other. The alarm systems go off and the blast doors close, trapping them inside the reactor.
Batman battles Dr. Double X's energy duplicate, and the human half explains he plans to unleash nuclear energy and increase his energy tenfold. Jason and Ronnie wander in and Dr. Double X tries to take them hostage. Batman fights them off and tells the civilians to get out, but Raymond's bum knee holds him back. Jason refuses to abandon him and helps him down the corridor. A blast of energy is released from the nuclear reactor, striking Raymond and Jason.
Jason wakes up and discovers that he can hear Raymond in his head. They realize that their hair is on fire, and quickly realize that they're in the same body. Dr. Double X spots the transformed Jason and attack. When the villain attacks, Batman lassos the villain. Realizing they need a recharge, the dual villain escapes. A highly intellectual Batman scans Jason and determines he's giving off nuclear energy and says they need to go to the Batcave. However, after they leave, another Batman emerges from the rubble and angrily goes to the Batcave. As he leaves, a Slacker Batman emerges from the rubble and goes to the Batcave.
At the Batcave, the intellectual Batman creates a suit for Jason to regulate his nuclear energy. Raymond, inside his head, argues with him and Jason realizes that Batman can't hear him.
Dr. Double X tries to get enough power to reenergize himself and free his energy self. Once they are powered up, they go in search of Jason.
Jason and Raymond at least agree that the Batcave is cool. However, when Jason wants to check out the nuclear reactor, Raymond tries to take control of it. The Slacker Batman arrives without Jason realizing he's a different one, and then goes off to get something to eat. The Aggressive Batman arrives and attacks Jason, and demands to know who stole the Batmobile. Jason and Raymond have no idea what's going on and Jason summons a nuclear blast with an inadvertent gesture. Aggressive Batman moves in but Intellectual and Slacker Batmen arrive. The Intellectual Batman concludes that the same nuclear blast separated him into his three primary components: intellect, strength, and what's left without the other two elements. Intellectual Batman tries to find a solution by testing Jason and Raymond, while Aggressive Batman does pushups and Slacker Batman relaxes. Jason soon discovers he has the ability to transform matter. Finally, Intellectual Batman figures out a way to separate Ronnie and Jason, and reunite the three Batmans. Slacker Batman informs them that Aggressive Batman has left to hunt criminals.
Aggressive Batman goes to a bar where supervillains have united to play pool. He drops in and tells them to surrender. When they don't, a fight breaks out. The other two Batmans arrive to assist and the villains are quickly subdued with an assist from Jason. Dr, Double X is nearby and captures Jason, and then escapes.
Intellectual Batman is able to track Jason's unique energy signature and the three Batmen leave. Meanwhile, Jason finds himself in a power draining chamber. Dr. Double X enters the other chamber and redirects the energy to himself to make him unstoppable. However, the Batmen arrive to stop him. However, the villain releases his super-charged energy self, which attacks the heroes. Working quickly, the three Batmen come up with a plan. Slacker Batman looks for the off switch while the other two Batmen attack the energy villain.
In the energy chamber, Jason and Ronnie start to split apart as their energy is drained away. Slacker Batman prepares to turn off the draining device, but the energy villain throws him away. Jason suggests that they work together and Raymond agrees. Working together, they break out of their chamber and switch places. The three Batmen lasso the energy villain, who realizes that he's losing power. There's an explosion and the reunited Jason/Raymond attack and knock out the energy villain. He refuses to go back into his human self, but Jason fires one last energy blast and reunites the two villains.
With time running out, the three Batmen refuse to reunite. Jason explains that the world needs the one and only Batman, and they agree. They enter the chamber and Jason powers their transformation, reuniting them into one Batman. The transfer device blows out and Batman congratulates him. Jason says that they've came up with a new name: Firestorm.
Firestorm as a character first appeared in Firestorm #1 (March 1978) and was created by Gerry Conway and Al Milgrom. High school student Ronnie Raymond was caught in a nuclear blast with Professor Martin Stein. The nuclear energy allowed them to merge their bodies and share consciousness, as well as giving the gestalt hero the ability to manipulate and transform inanimate objects. Since Stein was unconscious during the blast, he could only contribute mentally to the partnership, and Raymond was the controlling influence. Firestorm went through a number of changes throughout the years, until Raymond's death at the hands of a magical sword. Jason Rausch first appeared in Firestorm Vol. 3, #1 (July 2004) and was created by Dan Jolley and ChrisCross. Rausch, a teenager, encountered the Firestorm energy matrix after Raymond's death and became its new host. Raymond's mental essence returned for a while, and often Rausch needed to merge with another individual to power the matrix. As of this episode's premiere, Rausch is linked with, and under the control of, an undead Black Lantern version of Raymond. The character seen here is a hybrid of sorts of both comic book versions.
Edward Nigma first appeared in Detective Comics #140 (October 1948) and was created by Bill Finger and Dick Sprang.

Dr. Double X first appeared in Detective Comics #261 (1958). Dr. Simon Ecks became obsessed with the idea of human auras and managed to create an energy duplicate of himself. The two went on a criminal rampage and were stopped by Batman, and have appeared erratically throughout the years since.
