Great P365 War

"With Equestria left in ruins, it seems that friendship and optimism isn't fading out just yet. We must defend Equestria and Canterlot City so we can put an end to another era of disharmony and darkness once and for all, and for Celestia's sake, we can't hold these evildoers off without any required assistance, even when it's Pika's fault."

--Su Ji-Hoon, The P365 Returns

The Great P365 War is a war waged between the Allied Forces of Harmonic Friendship and the New Group P365 that it would be happened in post-Last Day of Equestria

Like different from the Great Crystal War, the Crystal Empire being allies with Equestria, Princesses Celestia and Luna being generals, Sweet Apple Acres adding a high-tech industrial factory to provide food for the front lines while the Apple family is producing both sweet and sour apples, Rainbow Dash joining the Equestrian army's Air Cavalry division and serving as commander, Pinkie Pie and Maud Pie joining the army's Rock Troopers division while Pinkie Pie's party animal personality is kept, Rarity and Fluttershy stay in Ponyville to help with the war cause, making soldier uniforms, the Mane Six is being reunited, the Castle of Friendship being the HQ against the New Group P365, Ponyville being rebuilt, and even making Sugarcube Corner a place where canned cupcakes are being produced.

While in the New Group P365's schemes, the New Group P365 have new allies from ghouls and mutants.most of Ghouls and mutants were being badly treated by Equestria that caused them join New Group P365. They deployed all types of zombies from Call of Duty Zombies and Group P365's schemes,so that they became against Equestria due to blamed Equestria for nuclear attack but also want restore Dazzle's pride.

They would use schemes from Group 935 to made their own strength, Tartarus still to be their main base like old Group P365.

While in Canterlot City, Equestria Girls faced to find about and defeat the New Group P365's schemes that they would find any survivors since Canterlot High School became main setting safely location.

Depiction in When the Cold Breeze Blows Away
In When the Cold Breeze Blows Away, Equestria faces a nuclear war with Zebrica with megaspells, nuclear weapons, and many other superweapons and weapons of mass destruction towards the end of the Last Day.

Several months later, the New Group P365 appears in Equestria's Arctic North, bringing the evil Onyx Sorbetstorm with it. According to Applejack, Sorbetstorm then revives the Group P365 and wages war on many nations of Harmonia (mainly Equestria, the Crystal Empire, the Griffon Empire and Gerasecia) and the Canterlot City, using aggressive zombie types to form his army of soldiers. Over the course of the next several months, the New Group P365 expands across Equestria, including the San Palomino Desert, the Badlands, and portions of Griffonstone.

Princess Celestia, Princess Luna, Princess Cadance, Twilight Sparkle, Flurry Heart, Big McIntosh, Starlight Glimmer, Sunset Shimmer, Noi and their subjects fight back against the invading New Group P365. The royal guards, Wonderbolts, Shadowbolts, Washouts, and other ponies are enlisted into the Allied Forces of Harmonic Friendship, serving as either soldiers or war effort supporters.

The Crystal Empire, the Griffon Empire and Gerasecia were joined the Allied Forces of Harmonic Friendship when they will fight back against the undead hordes of New Group P365

Meanwhile, Equestria's finest research mages look for a counterspell for the Elements of Necromancy.

History
The history of the Great P365 War was presumably identical to that of the Great Crystal War timeline (or the Sombraverse), except that the Mane Six still have their own cutie marks, and their personalities and their memories from the pre-Last Day times were kept, and there were a lot of major changes, which are much better than that of the Sombraverse, like for example; robots and renewable energy eased the lives of many workers who were working for the war effort.

Due to India and Pakistan's actions to cause an interdimensional superweapon apocalypse, this post-apocalyptic Equestria saw Onyx Sorbetstorm succeed in reviving the Group P365 (with the New Group P365 as its name, and making a lot of aggressive zombies and the undead hordes to serve as his own undead minions, undead henchponies and undead troopers. With this army at his back, Sorbetstorm launched an assault on many nations of Harmonia (such as Equestria, the Crystal Empire, the Griffon Empire, Gerasecia, Canterlot City, Yakyakistan, the Changeling Federation and many others), resulting in the Great P365 War. At the time of Twilight and Spike's emergence from Stable 111, he had managed to seize control of half of Equestria despite the brave efforts of Princess Celestia, Princess Luna, Big McIntosh, Princess Cadance, Shining Armor, Flurry Heart and the Equestrian Resistance. Ponyville is not abandoned because of the interception of balefire bombs, nuclear weapons and superweapons (making it one of Equestria's most prominent Safe Havens), and Sweet Apple Acres was converted into a factory as part of the war effort, but like the paragraph from the above (and unlike in the Sombraverse), it is very clean and futuristic-looking.

Upon meeting Applejack, Twilight explained how she had come to be there, and was then informed of the state of affairs by Applejack while they were happily reunited to see each other again. These included Rainbow Dash (for the Wonderbolts Air Cavalry), Pinkie Pie, and Sombraverse Maud Pie (both for the Rock Troopers) serving as soldiers under Celestia, Luna, Big Mac, Cadance, Shining Armor, Flurry, and later, both Noi and Twilight, while Fluttershy and Rarity operated in the newly-rebuilt/walled town of Ponyville. Rarity (unlike in the Sombraverse) didn't relocate to Manehattan (but she stayed in Ponyville) to help produce uniforms in her home, the Carousel Boutique. Horrified by this war and the aftermath of an apocalyptic event, Su Ji-Hoon, the Mane Six and all of their friends and allies set out to save Harmonia (and maybe some other worlds that are either affected or unaffected by the Third World War) from falling under the hands of the New Group P365 and their dreadful allies that are bound to destroy harmony and friendship.

 * Sweet Apple Acres adds a high-tech industrial factory to provide food for the front lines while the Apple family is producing both sweet and sour apples.
 * Rainbow Dash joins the Equestrian army's Air Cavalry division and serves as commander. During the war, she loses her left wing, and it is replaced with a cybernetic limb actuator.

Other Impacts

 * Cutie Marks or Element of Harmony never lost but caused New Group P365 create new disharmony elements.
 * The Mane Six's personalities are kept in a different way.

 * Pinkie Pie retains her outgoing, cheerful and energetic personality, including a fondness for having parties. This time, she'd treat many raiding parties as a real party.
 * Rainbow Dash is more powerful than ever before due to her awesomeness.
 * Rarity elaborates some small gems on military uniforms for her fashionista personality.
 * Twilight Sparkle is one of the strongest leaders of Equestria, judging by her high intelligence.
