We then go to Salamandria to see present day Mona Lisa, now nineteen, and Sal Commander, older and scars fully healed. We learn through their conversations that Salamandria is healing after another invasion from Lord Dregg. During their conversation we discover that Mona’s parents left her under Sal’s care while they went to war against the Triceratons, but they never returned, signifying that they were killed in battle. (Finally giving Mona backstory!)

During this time we learn a little about Mona’s life on her planet, constantly training or working, never having a break or a chance to just relax and act her age, but instead has to grow up quickly and act mature. We get the idea that she’s starting to get bored of her life and wants to do something fun. We see moments where the men on her planet make advances at her but she doesn’t give them the time of day. We see the females spread rumors about her, showing that she doesn’t really have any friends, for word has spread that she’s been wooed by “some lowlife being from an uncharted disgraceful planet” and that her relationship with this guy was the reason for Dregg’s invasion in the first place (referencing back to the Evil of Dregg episode)

That’s when Mona and Sal are called in to see the head general who informs them that after fourteen years Newtralizer has finally come out of hiding and has been spotted on a worthless planet called Earth. 

Cue Mona thinking of Raph doing push ups.

While Mona continues day dreaming, Sal Commander is assigned to go to Earth and capture Newtrailzer and bring him back so he can face his long awaited trial for his crimes. Sal agrees and heads off to his ship, bringing Mona along with him as backup. In the ship Mona, trying not to be too obvious, suggests that since they are going to Earth they should contact the turtles and ask for their assistance in their mission. Sal doesn’t want them to get involved in dangerous tasks, but Mona convinces him that with their help they can easily take him down. Knowing that secretly her real reason is to just see Raphael again, Sal agrees.

We then finally go to Earth, finding Raph watching Spaceheroes: The Next Generation with Leo. After watching the main hero, Captain Ryan, lose the woman he loves we see Raph have sympathy for him, silently showing us that he understands that pain. Leo however shrugs if off, saying Captain Ryan will get over it, but Raph gets angry and storms off to find something else to do, calling the show stupid.

He goes to see if Donnie wants to hang out, but Donnie is hanging out with April in his lab, working on a new science project together, but there more focused on training than working. He tries calling Casey, but he tells him he’s got a “hot date”. Then Raph goes to Mikey’s room to see if he wants to hang out, but Mikey is busy chatting with Renet via holograms.

It's when Raph overhears Mikey say that him and Renet are now in a long distance relationship, that’s what gets to him. Raph storms off to his room. To take out his frustration we see Raph play with his drum set. After he’s done, Raph starts to rant to Chompy, making fun of his brothers for being lovey dovey with the girls. That’s when Raph gives his lone wolf speech and how he doesn’t need love or romance in his life, but before he finishes his false claim, his old space helmet begins to buzz. Raph gets the call from Mona and tells him that her and her commander are coming to Earth for a mission and need their help. Raph gets excited and runs into the door just like in the episode.

We then get a moment of Raph calling his brothers, April, and Karai (who is now at the lair stopping by for a visit) in the main room of the lair where he excitedly explains to them that Mona (and Sal) are coming to Earth. Raph explains that Mona sent him the coordinate to where and when they’ll be landing and that they need to meet them there. April and Mikey have a fanboy/girl moment, happy their OTP is reuniting. Karai, confused, looks at Leo and asks him “Who’s Mona Lisa?”. Leo smiles and jokingly but also seriously says “Raph’s girlfriend,” and walks away leaving Karai with a shocked look on his face. The scene ends seeing the team leaving the lair as April and Mikey continue their freak out, Raph freshens himself up to look good for his lady, as Karai screams, “Why did no one tell me my brother has a girlfriend?!?!”

We then get a short moment of seeing the Utrom living a happy peaceful life, for they have reclaimed Dimension X as their home. The happy moment is interrupted by Newtrailzer who begins attacking the Utrom. We see the Utrom council watching this occur through and screen and worry for their people, wondering what they should do. That is when another alarm goes off informing them that more Salamadrians are entering the Milky Way Galaxy and are heading towards Earth. The Queen, worried that they are a hostel like Newtailzer, sends Bishop to capture these other Salamadrians and see what they want, for they already have one Salamandrian problem and they don’t need another.

We go back and the episode goes similar from there. Raph and Mona reunite, the team splits up to find Newtrailzer, Raph and Mona shortly catch up (with an added bonus of Raph bringing his flirt on and more focused on Mona then the actually mission), Bishop joins the fight, but then things get different. After the team escapes Newtrailzer and hides out in the Utom base they don’t get attacked by Newtrailzer like in the episode. Instead the council gives the team the weapon that can stop Newtralizer and absorb his powers. During their conversion to devise a plan the council suggests they need more reinforcements. Raph then comes up with an idea, knowing the perfect person to help take down Newtralizer.

With their new weapon, the team heads to the Mighty Mutanimals lair, where we find Casey and Shini also hanging out with them. Sal and Mona meet Slash and his team. Mikey introduces his friends to Sal, while Raph introduces Mona to Slash. Slash makes a comment that Raph has told him about Mona countless times, embarrassing Raph slightly. After a mini moment of Mondo Gecko trying (and failing) at making a move on Mona, Raph explains to Slash that Newtrailzer is back and they need his help since he knows more about him then the turtles do, for he was once his partner. Sal has a moment with Slash, like a “I understand what you went through” kind of moment. Slash agrees to help while the rest of the mighty mutanimals, Casey, and Shini, agree to help as well.

The fight goes similarly, just with the inclusion of the Mighty Mutanimals, Casey, and Shini. We then get the moment where everyone splits up and Raph and Mona are alone together again. This is when they have their conversation about Mona staying on earth after the battle is over. Mona declines and tells him that her job is to fight for glory and honor as a Salamandrian. Raph tries to convince her by telling her that she can fight on earth and how there's so much for her on his planet. Mona begins to feel unsure. Raph then hits Mona with how he’s been feeling about their long distances relationship. He tells her he doesn’t want to keep living in wonder if he'll ever see her again or not. That he wants to be with her and not keep going with a fear that one day they never see one another again. Mona tells Raph that she does care about him, it's just that who they are and where they’re both from makes this so difficult, so them just being together is a risk. Raph tells Mona he’s willing to take that risk to be with her. Before Mona could say anything, Newtrailzer makes another appearance and begins fighting the turtles and mutanimals so Raph and Mona need to help the others, but before they do, Raph grabs Mona’s hand and looks at her. He asks her if she could at least think about his offer. Mona agrees.

They all fight Newtrailzer but then the power in New York goes out. It is discovered that Lord Dregg is here and has teamed up with Newtrailzer to invade Earth. Dregg's ship lands as Newtralizer teleports inside the ship. 

The turtles and friends look on to Dregg’s ship to the two villains eviling looking down at them, but they weren't alone. Dregg and Newtrailzer had a third ally, a little shorter than them as his eyes glowed an evil orange. The team couldn’t make out who it was at first. The third ally jumped off the ship and perfectly landed to the ground in front of the turtles. 

The turtles, April, Casey, Mona, and Sal look at Dregg's new ally in a heartbroken shock. It was Fugitoid, now run down with missing parts of his robot body replaced with dark rusty metal patches. His eyes no longer glowed a bright blue but a dark orange. 

Fugitoid gives them all an evil grin asking them if they missed him. Fugitoid explains that it is their fault that he’s like this, accusing the turtles of abandoning him and leaving him to die, using him just to destroy the black hole generator. The turtles are confused for that is not what happened. They try to get through to him but he doesn’t listen. Fugitoid begins to attack them while taunting the turtles, April, Casey, and the Salamandrians. Fugitoid takes them down practically effortlessly as Dregg and Newtrailzer watch in amusement, calling him their “new toy” and Dregg mentions he’s glad he “fixed and kept him”.

Donnie then puts the pieces together and figures out that Dregg must've found Fugitoid’s pieces after he was blown up to destroy the black hole generator (back in season 4), put him back together, and rebooted him and his memories to believe that the turtles and friends are the bad guys. Newtrailzer does one final lighting attack throwing multiple shots at our heroes and as everyone runs for cover, the lighting hits Raphael. He screams in agony as he fades from existence. 

Everyone screams and cries for the fall of their friend as the three turtles cry for the “death” of their brother. Full of rage for hurting her love, Mona Lisa draws her sword and attacks Newtrailzer with all her might. We get a quick Mona vs Newtrailzer fight (with it being a parallel to the Raph vs Dregg fight when he hurt Mona).

Soon however, Newtrailzer beats Mona and Sal rushes in to protect her, as Mikey uses the Utrom weapon on Newtralizer, Sal orders her to run with the others somewhere safe. There is no time for goodbyes. Dregg sends down his insect army and starts his invasion. As Newtrailzer, frees himself from the weapons hold and grabs Sal Commander as hostage, Dregg’s minions capture Leonardo and the mighty mutanimals, except for Slash. With one fallen and some captured, the team retreats as Dreg takes over the city.
