Official Description


Somewhere in outer space, a Salamandrian fighter force travels through the cosmos, lead by Mona Lisa and her superior, Sal Commander. However, their general R'Kavaka soon comes on a hologram with news that a rogue Salamandrian named 'K'Vathrak' (whom Sal Commander has a grudge against as it was that rogue Salamandrian who cost him his left eye) had been spotted on Earth and is hunting benevolent Utrom. Realizing that planet Earth is where Raphael lives, Mona and Sal Commander break off from the fleet to head to Earth.

In New York City, three Utrom hunt for the rogue, who ambushes them in an alleyway. It is implied that they are killed by the Salamandrian.

Meanwhile, after watching the latest episode of "Space Heroes: The Next Generation," Raphael is ticked off by how each of his brothers has a love interest and he doesn't. April and Donnie are too busy having a popcorn fight to watch Space Heroes; Leo and Karai are playfully sparring in the dojo whilst exchanging some flirtatious banter, during which Karai states that even though she has a crush on him, she won't go easy on him (a possible reference to tough love) while Mikey appears to be talking to Renet, having formed a long distance relationship with her.

Raph storms out to his room to vent his anger on his drum set, in addition to sulk and rant his complaints to Chompy, only to soon get a call over his space helmet, that Fugitoid gave him, from Mona, who reports that she is on her way to Earth with Sal Commander. Raph is ecstatic by this. When Mona and Sal Commander land on a rooftop and meet up with April, the Turtles, and Karai, we see Raphael immediately embrace Mona Lisa. Seeing this, Karai finds it weird that Raph is in love with a newt, but also shows some unsettled discomfort around Leo's comments on Raph having weird taste, which is basically reminding her that she herself is dating a Turtle. After this, Mona Lisa and Sal Commander explain why they are there, and the Turtles realize the rogue Salamandrian is really the Newtralizer, going after Utroms and traveling back and forth between Earth and Dimension X to heedlessly wreck havoc without mercy.

Meanwhile, at the Utrom High Council, Queen, Pawn, and Rook are concerned about what's happening, and ask Bishop to investigate. Bishop agrees to take an Earth Protection Force commando team to deal with the Newtralizer and the recent arrivals of Mona and Sal Commander on Earth as well. Soon enough, Bishop and the EPF commandos attack Sal Commander and Mikey after they split up from Raphael and Mona.

Before going after them, Mona explains to Raphael that she and Sal Commander had to deal with Lord Dregg, who survived his presumed death by the Triceratons, and managed to still launch his invasion of Salamandria. They fought him off, but Dregg swore to return.

After rescuing Mikey and Sal Commander, they are surrounded by Bishop and the EPF commando team. Thankfully, once Raphael and Mikey explain that Mona and Sal Commander are the ones who helped the Utroms previously in Dimension X with the Kraang, Bishop and the EPF release them and agree to aid them against Newtralizer, with Bishop acting as the bait to draw Newtralizer out. Karai and Leonardo team with Donatello and April to investigate and ambush the Newtralizer. Despite their best attempts, Newtralizer proves too powerful, and once Leo and Karai (along with Donnie and April) arrive before Newtralizer can eat Bishop, who has them retreat back to the Utrom High Council chamber, where Rook reveals a device that could help deal with Newtralizer, but he arrives, disables Queen's Miss Campbell body, decapitates Rook, and nearly eats Pawn, before Bishop leads the Turtles and everyone else back to NYC. However, as they fight Newtralizer at a power substation where he fought Leo, Karai, Donnie, and April earlier, where April weakened him with water, he manages to apparently electrocute and disintegrate Mikey. Enraged, Raphael zaps him with Rook's weapon, but before it can destroy him completely, electromagnetic interference saves Newtralizer.

The reason soon presents itself: Newtralizer's old friend and ally, and the one that the Turtles hoped they would never see again: Lord Vringath Dregg, now in a new living command ship, which quickly begins laying Vreen eggs to begin taking over the city. As Newtralizer retreats to the ship, the Turtles, April, Karai, Salamandrians, and Bishop look up in disbelief and shock as things have just gone from bad to worse. The episode concludes with Karai and Leonardo looking up into the sky in horror as Lord Dregg's ship hovers overhead, and Vreen insects start infesting the city.

Part 2

.As Lord Vringath Dregg's command ship begins hovering over New York City, and opening fire (secreting slime where Vreen insects grow and capture the humans), the Newtralizer laughs maniacally. Enraged, Leo pulls out a katana and tries to slash the newt, but he quickly disappears. As they stick together, Donnie asks what they should do. Before anyone can say anything, Leonardo gets abruptly seized and captured by a Vreen insect, who abducts him to Lord Dregg's ship. Concerned by this, Karai reaches out to save no avail. She watches in horror as more Vreen insects hover overhead before being tackled down by a Vreen who also tries to capture her. More Vreen come, attacking the Turtles and their allies. Sal Commander and Mona Lisa are eventually able to fight off the Vreen with their laser guns. The group is forced to retreat (lead by Bishop) but Sal Commander is also captured and abducted to Dregg's ship. The others are forced to retreat and find somewhere to hole up for the time being. The group takes shelter inside an abandoned warehouse, and barricades the walls and entrenches. During that time, Bishop blames Mona for Dregg's invasion, citing that he must have followed her here when they came looking for Newtralizer. As Raphael, Donnie, April, Karai, Mona Lisa, and Bishop avoid the Vreen swarming the city, they are shocked to find the Channel 6 building being made into a hive where the citizens of New York are being taken by the Vreen to be cocooned as Dregg's prisoners.

Soon after, Newtralizer arrives to finish them off, but in a strange twist, Michelangelo reappears, now sporting powers similar to Newtralizer, and still very much alive, but despite his aid, Donnie and Karai are captured as well by more Vreen, leaving April, Raph, Mikey, Mona, and Bishop to return to the lair to regroup and plan their next attack. On Dregg's ship, Newtralizer complains about destroying the whole planet, but Dregg intents to capture the human/Terran population and make them into living egg sacs for his Vreen army.

Back with the good guys, Bishop will have the Earth Protection Force send in a team to help deal with the Vreen and Dregg's command ship, while April, Mona, Raph, and Bishop attempt to provide a distraction with the Turtle Mech for Mikey to infiltrate and free the others. After the EPF forces are overpowered and forced to regroup, the Turtle Mech does its best to deal with Dregg's command ship before being destroyed, attempting to weaken it with pesticide and fire, which helps as further damage from within allows the EPF to take notice and resume their own attack from the outside to cause even more damage.

After Raphael, Mona, April, and Bishop get inside, Mikey frees Sal Commander, Leo, Donnie, and Karai, and after Raphael gives Dregg a good dose of electrocution, knocking him out cold after Mona sees he's vulnerable to it after zapping him with Rook's weapon, Mikey and Sal Commander end up in the power core of Dregg's ship, where when Newtralizer is about to take out Mikey for good, Sal Commander gets his vengeance for the wounds Newtralizer gave him by knocking him into the ship's power core, setting off a chain reaction that causes Newtralizer to overload the power core with his own electrical abilities, threatening to destroy the ship, and everyone on it. Mikey puts himself in harm's way with his powers to try and delay the inevitable to give everyone else time to abandon ship.

Realizing its fate, Dregg's ship takes flight in a vain attempt to escape, but after everyone else bails out and lands on a rooftop, they watch as Dregg's ship explodes, hopefully killing the alien warlord once and for all, and the Newtralizer as well. Mikey soon emerges completely unharmed and alive, and as everyone celebrates, Bishop uses the device meant for Newtralizer to remove Mikey's electrical powers, but rendering him stripped of his ninja gear and clothes as well, leaving him naked, save for his shell. The mission over, Mona and Sal Commander prepare to return to Salamandria to report to their general of what has transpired, but Mona requests that she be transferred to Earth to protect it from further threats. Understanding her reasons for staying, Sal Commander grants his Lieutenant her request, and after Raphael silences Bishop when he tries to counter this (by beheading him), Raphael suggests that Mona hook up with the Mighty Mutanimals and work with them. With that, Mona Lisa and Raphael kiss and caress. Though April admires this, the others (Karai, Leo, Donnie and Mikey) are largely disgusted and unsettled.
