Plot
Princess Celestia and Princess Luna were ready to be retired, Cozy Glow and Tirek had been summoned from the cages to Grogar's cave with Chrysalis, and Grogar orders King Sombra to attack Crystal Empire, again. The Mane Six were starting to have a battle against King Sombra once again after the last time Sombra had died from Season 3. But after The Mane Six thought they had to defeat Sombra, King Sombra suddenly comes back from nowhere and destroys the Tree of Harmony, and destroyed the Elements of Harmony, and he caused a lot of plants, were grown all over Ponyville. The Mane Six had managed to destroy a lot of Plants and made it to Canterlot, unfortunately, the ponies in canterlot were still occupied, and acting weird, along with Starlight Glimmer.

The Mane Six and Discord managed to do so, and once they got to the Castle, Sombra was already there, and Sombra beats up Discord, and Twilight and Mane 5 make even power and finally kills Sombra once more. and Celebrate, back at the Grogar's Cave, Grogar was furious over Sombra, defeat, but their evil plan wasn't over yet.

Why It Rocks

 * 1) This is a very great start of the final season of My Little Pony: Friendship is Magic, by having a lot of powerful materials that weren't shown in eight seasons.
 * 2) Grogar finally returns in this episode, but he is a very powerful villain that wants to end the ponies in all of Equestria, for an evil plan, which is cool, despite it being disappointing he will turn out to be Discord in duisguise.
 * 3) The idea of having a retirement of Princess Celestia and Princess Luna so Twilight Sparkle be a real princess at Canterlot is a decent idea, even when any final season of having an "leaving the leader" at any final season of any show.
 * 4) The Mane Six, and Discord's actions against King Sombra is even more powerful than what Twilight did in Season 3 in the Crystal Empire.
 * 5) King Sombra is finally back to terrorising the Crystal Empire again, and now goes to Ponyville, and Canterlot too.

Bad Qualities

 * 1) The destruction of Tree of Harmony is directly spoiled in the first trailer of Season 9.
 * 2) Sombra's personality here is unfitting and contradictory. In The Crystal Empire and The Cutie Re-Mark, he was careful and serious; but now he's reckless and flamboyant for some reason.
 * 3) *The expanded universe gave him a superior return arc (comics "FIENDship is Magic" and "Siege of the Crystal Empire"), which turned him into a deep yet consistent character and even gave the Empire some interesting and significant worldbuilding. But this premiere ignores and decanonizes it.
