During a thunderstorm, rain showers upon Paradigm City’s prison. Inside one of the cells, Beck is imprisoned along with his two henchmen, T-Bone and Dove. The henchmen have a wire from the prison’s security system attached to a fork which Beck is trying to use as a lightning rod to help them escape. Dove proclaims he won’t die for Beck, causing Beck to push him around. This causes the wire to snap. Beck rushes to hold both ends of the wire back together just as lightning strikes, electrocuting all three of them and causing Beck’s hair to be fried in an Afro-type form. At his mansion, Roger continues to sleep late into the day as usual, causing Dorothy to frantically play at the piano so as to wake him up. Roger heads out, having tied the piano shut such that Dorothy can’t play it any longer. Roger heads to a dome to meet with his latest client, who works for Yoshifura Yakamoto Industries, a construction company that built Paradigm’s domes. Roger arrives at a home where he is greeted by three Asian businessmen who lead Roger through an old fashioned Japanese-style home. At Roger’s mansion, Norman works on finishing dinner, but Dorothy believes Roger won’t be arriving for it. Norman says they must be ready nonetheless. Dastun arrives and tells Dorothy and Norman that Roger has been kidnapped. Dorothy asks how he knows for sure and Dastun shows him Roger’s tie. Meanwhile, Roger is being suspended on a crucifix by Beck, who has a device cover Roger’s head. Beck, along with his henchmen, shows Roger off to a group of Asian businessmen, saying that Roger is the dominus of the evil MegaDeus spreading fear in Paradigm. Roger wonders how Beck knows that he is Big O’s pilot. The businessmen take a number of photos of Roger. Beck promises to make a presentation on behalf of the businessmen to Paradigm Corporation. At Roger’s mansion, members of the Military Police set up an apparatus so as to record any telephone calls. The phone starts ringing and Dastun pleads with Norman about how to respond to the kidnapper. Dorothy, ignoring them, picks up the telephone and talks to the kidnapper, Beck. Dorothy confirms to Dastun and Norman that Roger has been kidnapped. Dorothy tells Dastun she promised the kidnapper she wouldn’t talk to the police and says she’ll handle negotiations on her own. Roger awakens and notices that Beck has constructed a replica of his head and torso which mimics him exactly. Dorothy departs Roger’s mansion on a bicycle with the ransom money and is pursued by Dastun.
Beck gloats about the money they are going to make and insists to his underlings to call him Dr. Beckland so they can continue to fool the Yoshifura Yakamoto businessmen. Roger tries using his watch to help him get him off the crucifix he’s being held, to no avail. He shouts at the replica at how long it will continue mimicking him. He’s finally successful in being able to activate a laser via his watch to help him release one of his arms. He calls for Big O, but Beck grabs a hold of his watch and traps Roger in a glass tube as he lunges at him. Beck expresses pleasure at finding out that the watch is used to call Big O. He puts it up to the mouth of the replica, which calls for Big O. Dastun and the Military Police continue to pursue Dorothy, who heads into the dome where Roger is being held. Suddenly, Big O appears and starts walking through Paradigm City. Beck shows Roger a video of Big O, which is being directed by the Roger replica. Beck tells Roger that he is going to make Big O sink into the ocean. The Roger replica reaches the shore and flies off the edge of a building into the sea. Big O is about to step off itself, but suddenly pauses. Beck is shocked, but is still confident that he’ll come out on top until he sees that Dorothy has arrived and captured both of his underlings in the spoke of her bicycle’s tires. Beck starts laughing and asks Roger if Dorothy is his lover. Roger says it’s preposterous, upsetting Dorothy. Dorothy jokingly tells Roger she loves him, upsetting him further, and then hands the suitcase to Beck. The suitcase opens, revealing not money, but watches, which dump onto Beck. Dorothy punches through the glass tube holding Roger, who tells her a negotiator only uses force as a last resort. Dorothy says she’s not interested in taking his job. Beck steps on a switch which activates a large suspended magnet, causing Dorothy to start rising into the air. Beck tells Roger he’s humiliated him three times and it won’t happen again. He tries to open the control unit in Dorothy’s head, but she has it set to prevent any such attempts, launching a metal boomerang that causes Beck to be suspended to the magnet by the neck. Beck tries to turn off the magnet, but the switch gets attached to the magnet as well. Dorothy gives Roger a new neck tie and Roger says he’ll need to thank her somehow. Dorothy says she has a favor to ask of him. Beck gets upset over Roger and Dorothy not paying attention to him. His henchmen arrive in a group of vehicles which are able to pull Beck off the magnet. Beck calls out for them to implement their final formation. He and his henchmen drive out into the domes where Beck calls for them to combine. The three vehicles combine into a MegaDeus, “Beck The Great RX3.” Roger stands before Beck The Great RX 3 and calls for Big O, which appears from behind him. Dastun had just arrived at the seashore where Big O had been standing and orders his men to head back. Roger asks Beck how he knew the truth about him. Beck says a memory just popped into his head that Roger was the dominus of the black MegaDeus. Beck The Great RX3 takes out a large red boomerang. Roger fires at Beck The Great RX3 with its machine gun arm, causing it to immediately collapse. Beck and his underlings are brought back to jail. Roger tells Dorothy that she made the grade as an apprentice negotiator. Dorothy reminds Roger of the favor she had asked. Back at his mansion, Dorothy returns to frantically playing the piano again, angering Roger, who is trying to sleep.
Beck returns once more in this more comedic-themed episode. The continuing storyline comes to a pause for this episode, which I didn’t particularly have a concern with since season 1, which to this point has been superior to season 2, was largely stand-alone episodes itself. This episode contains some of the show’s funniest segments, including Beck’s episode-long Afro hairstyle, Dastun’s crazed reactions when Roger is kidnapped and the Roger replica. Beck The Great RX3, which is formed from three vehicles combining, appears to be a homage to various giant robot shows from the 70s and 80s which featured a similar setup. Roger defeating it with such little ease is in line with the comedic nature of the episode. Not a great episode, but still an improvement over the last one.
