In the Turtle Lair, the TMNT are doing various things. Leonardo practices his ninjutsu with Master Splinter while Mikey elaborates on why he loves comic books and super heroes. Suddenly, the Ultimate Drako appears with the Time Scepter. The evil villain raises his staff which shoots bolts of energy that encompasses our heroes in a flash of eerie light, freezing them in mid-air. Fade in from the blinding light as we see Mikey is now the only one left in the lair, only, it’s not exactly the lair. It’s an updated and futuristic version of the Turtles' home, as if from an alternate reality. Mike begins to explore when a disembodied computer voice asks him where he wants to go. An elevator appears from out of the floor. Michelangelo enters the lift and requests to be taken to see his brothers. With that, the elevator doors close and it drops at a phenomenal speed, taking the Turtle to a desert landscape. As Mikey explores this new environment, he comes upon four superhero Turtles (Graviturtle, Shellectro, Griddex, and Blobboid) facing off with a group of super villains calling themselves the Terrorkinetics. Mikey is caught in the super battle and soon pinned to the ground by a huge, animalistic robot. The Super Turtles have no idea who the shell Mike is, so Griddex orders the computer to shut down the program, revealing the villains (and the desert) to be a holographic simulation. The Super Turtles decide to scan Mikey to see if he's a threat, so the ninja is taken back upstairs and given the scientific once-over, revealing that he has no super powers. While Michelangelo is strapped down, he begins to phase shift and it's determined that he's from an alternate dimension. Mikey figures he may be going home, but Graviturtle suggests that perhaps their dimension is trying to erase him. Suddenly, a helicopter arrives at the lair and Mayor April O'Neil emerges with her security team. April informs the Super Turtles that they must stop a doomsday device that’s set to go off in Megatropolis. As the Super Turtles are given the details by April, we discover that she is the mayor of Megatropolis. Casey Jones clumsily disembarks from the chopper and we learn that this dimension's Casey is a non-violent politician working for O'Neil. With the briefing completed, the Super Turtles prepare to set off. Mikey begins to phase shift yet again, and bids his new friends farewell... except he stops phasing and stays put in this dimension. With that, the Super Turtles take off to face their foe, with Mikey in tow. Cut to Sliver's Tower. Once Mikey and the Super Turtles arrive, they knock down the building's defenses and then break into the Throne room, preparing to do battle with their arch nemesis, a villain named Sliver. To Mikey’s surprise, Sliver is none other than an evil version of his own Master Splinter! We see Sliver's appearance as red eyed mutant rat with armor (similar to Shredder's). When Michelangelo states that they said they lost their Sensei, the Super Turtles stated that they lost him... to evil. As the Super Turtles attack their former Sensei, they prove to be no match for their mentor, who has all of their powers and more knowledge on how to use them. Sliver traps the heroes in an Utromidium cage, which nullifies their powers. With no way out of the cage, it seems that the Super Turtles cannot stop Sliver from setting off the Penultimate Nullificator and destroying all life outside the tower. But Mikey comes up with a plan! Mikey calls out to the evil rat and asks for an audience with him - in private. Sliver grants the request, freeing him from the main cage but keeping him trapped in a small sphere, which floats up to villain's throne. Once he's face-to-face with the nefarious rodent, Michelangelo pretends that the TMNT and Splinter rule the world in his dimension, and he volunteers to help Sliver do the same here. Sliver desperately longs for his "sons" to fight by his side, so he buys the story and frees Mike from his personal cage. Only it isn’t Mikey, it’s Blobboid disguised as Mikey! Blobboid seizes Sliver's staff and uses it to release the others. The battle is renewed, but once again Sliver defeats his pupils, revealing to possessing all their powers, leaving only Michelangelo to face the super-powered evildoer. With quick movements and guile, Mikey defeats Sliver by snatching his cane and trapping him in his own cage! As soon as the villain is captured, Mikey once again begins to phase shift. Unwilling to leave the Super Turtles with the Penultimate Nullificator about to go off, Mikey turns to the Sliver and asks how to stop the Nullificator. However, the villain states that he never intended to stop it, so there is no way to shut it off. Graviturtle volunteers to fly the device into the stratosphere at the cost of his life. However, Mikey suggests that if they can reverse its signal, it will only destroy Sliver's tower and not the world outside.

The episode begins with Viral awakening in an unknown location. She hacks into the system she's trapped in and finds Donatello and Cody trying to repair the time window, so the Turtles can go back to their own time. After realizing that she is seeing them from Serling's point of view, Viral concludes that she's still inside of Serling due to their last encounter on the moon. Viral then reveals that the decompiler program that seemingly killed her did greatly damage her, but her advanced systems managed to keep her alive and after some time has gone by, Viral's damages are 97.005% healed. Viral then vows to take revenge on the Turtles but then, it appears that Cody and Don have completed repairing the time window and the Turtles will be on their way home. This news pleases Viral, as it gives her a perfect chance to make the Turtles suffer to the fullest extent. Before the Turtles and Splinter leave, they leave everything behind, including their weapons. Splinter thanks Cody for his hospitality and believed that a bond had been made that will last forever. The turtles say goodbye and enter the time window. However, once the Turtles and Splinter enter, Viral emerges out of Serling and enters the time window herself, infecting it and taking complete control over it. Upon Viral entering the time window, it explodes, taking Serling into it. In the time window, Leo suspects something might be wrong after he saw a surge of red energy enter the time window. The Turtles, Splinter and Serling almost make it to their time, but Viral alters the time window and sends them to a different time instead. The first time period Viral sends the turtles, Splinter and Serling to is the Jurassic period, complete with a hostile dinosaur. Leo suggests for Serling to use his weapons, but Serling sadly admits that while inside him, Viral had disabled all his weapons. This causes Raph to criticize Don's idea of leaving everything behind, including their weapons. Mikey launches a poor attack against an aggressive dinosaur, by attacking it with a stick, which causes him to be easily defeated when he is knocked to the ground by the dinosaur's tail. Meanwhile, the aggressive dinosaur is about to move in for the kill on Leo, Don, Raph, Splinter and Serling, but Mikey comes in riding the Triceratops and charging at the dinosaur. This causes the dinosaur to flee and causes Mikey to name the Triceratops Zog II. Viral acts less than impressed over the fact that the Turtles defeated the dinosaur and sends them to another time. The second time period Viral sends the Turtles, Splinter and Serling is the dark medieval ages. The moment everyone arrives in this time, they are all attacked by an army of knights. The Turtles take some time to combat the knights, but Serling is taking quite a bit of abuse from the knights. Don gets an idea when he remembers that the decompiler program is still installed in Serling's drive. However, Leo reminds Don that Serling's weapons were deactivated, but Don explains that with more advanced technology, he might be able to get Serling's weapons back up. Although Raph argues that the technology more than likely doesn't exist in the medieval times, but Don responds by saying that if Viral could somehow send them closer to their time, he might be able to then. This gives Mikey an idea. Mikey goes up to Viral and actually manages to convince Viral to send them to their time, but he had to make it sound very, very bad. Viral send the Turtles, Splinter and Serling to yet another time. When the turtles are transported to the time period it appears they have been sent back to their own time. But Viral sent them to their time during a war between The Utrom Shredder, The Tengu Shredder and a new armored menace called The Cyber Shredder. The Cyber Shredder slashes Serling in the chest, greatly damaging his systems. The Cyber Shredder proceeds to attack the turtles but is blasted by the magic of The Tengu Shredder, who claims that the Turtles shall be his prize for victory. The fight between the three Shredders drags on and Don isn't too confident of Serling's survival, after looking over the damage The Cyber Shredder dealt. The Turtles are then confronted by a man with long red hair, a small red beard, and wearing gold and blue armor (later revealed to be Master Khan) who claims to have destroyed the Turtles himself. The man attacks the Turtles and proves to be a highly formidable opponent. Leo and Don lose their attention towards the man when he is blasted by the Tengu Shredder and when they see that the Cyber Shredder slashed through The Utrom Shredder's armor, revealing to be Utrom technology inside, something that can easily repair Serling. The Turtles and Splinter damage the Utrom Shredder as much as they can, but his armor is too strong, and the Turtles don't have any weapons with them. Splinter then gets an idea and goes over to the fight between the other two Shredders.

Vegeta and Nappa emerge from their space pods and Nappa wipes out East City with a single devastating blast. They then fly off towards the island where Piccolo and Gohan are in search of the Dragon Balls. Krillin arrives first, and the three face off with Vegeta and Nappa. Piccolo learns for the first time that he is a Namekian when told by Nappa. At Vegeta's order, Nappa plants seeds in the ground, and six Saibamen are born. Tien Shinhan, Chiaotzu, and then Yamcha fly in to join in the battle. Vegeta suggests they have a "game" of one-on-one. Tien faces-off first against a Saibaman. Tien overpowers the Saibaman but before he is able to finish it off, Vegeta destroys it as incentive to the remaining five. Next, Yamcha decides to fight in place of Krillin, but the Saibaman latches onto him and self-destructs, killing Yamcha outright.
