As you all are aware, it seems this generation of My Little Pony is about to come to an end, with a new generation coming in 2020(Wish the Simpsons and Family Guy did the same thing).  But that being said, I had my own idea for a My Little Pony reboot.  I call it "My Little Pony: Orphans of Equestria."

The series would be much darker than Friendship is MAgic, with a color scheme inspired by Steven Universe.  Also

Backstory: Equestria.  A place where Ponies of all sorts trot and gallop their way through.  A place made of Magitek.  Magic-based Technology.  But under all that happiness lies a system rotten to the core.  Once Equestria had Princesses and a Parliament that ruled with a kind spirit.  It is now ruled by Chancellor Abacus Cinch, with an Iron Hoof.  The whole world now lives in a facade of harmony, with non-Pony species being rounded up into slave camps.  

Note: With the exception of Nicole Oliver and Iris Quinn, every Pony will be recast in terms of Voice Actress

Celestia Del Sol(Ideal Voice Actress: Nicole Oliver): The Main protagonist of the story.  Long ago, Celestia and her sister Luna were cast out from Equestrian Leadership by Abacus Cinch.  Since then, she has dedicated her time as caretaker of orphan ponies, with her assistant Sunset Shimmer at her side.  But deep on the inside, she is building up a rebellion to save her own kingdom from Cinch.  Since then, she has been on the look out for her sister Luna Della Notte

Sunset Shimmer(Ideal Voice Actress: Will be recasted.  Some ideal actresses include Britt McKilip, Chiara Zanni, and Sophia Ewaniuk) The assistant to Celestia.  Long ago, Sunset Shimmer lost her parents to a horrible house fire, and has been adopted by Celestia as a surrogate daughter.  She sees the world as a cruel a bitter place, all while Celestia tries to reassure her that it's far from it.

Abacus Cinch(Ideal Voice Actress: Iris Quinn): Chancellor of Equestria, now its sole ruler.  She overthrew Celestia and Luna to become the ruler of Equestria, even going as far as to abolish the Parliament.  Her dream is to create a world where only the strongest Ponies rule, and everyone else is used only for mining out all the resources of the entire planet.  A cold and cruel leader, she stops at nothing to gain what she wants.

Twilight Sparkle(Ideal Voice Actress: Will be recasted): An orphan unicorn child.  She is seen by Sunset Shimmer as more of a younger sister.  It is said that she is one of the six children of Harmony that serves as the means of protecting the innocent from evil(Take a wild guess who the other five are).  She is more upbeat and full of life compared to Sunset.

Starlight Glimmer(Ideal Voice Actress: Will also be recasted): Another orphan unicorn child, and the younger sister of Twilight Sparkle.  She was traumatized to the loss of her own parents and has trouble readjusting her life.  Sunset and Twilight do what they can to help out their younger sister.

Tempest Shadow(Ideal Voice Actress: Ashleigh Ball): The number one soldier of Abacus Cinch, and the leader of Cinch's Templars(Basically a form of a Secret Police).  She is as ruthless as her master, and will stop at nothing when it comes to enforcing her rule of law.  

Diamond Tiara: In the original, she was the spoiled rich alpha bitch of Spoiled Milk and Filthy Rich.  This time, she is the daughter of Abacus Cinch.  Unlike her previous counterpart, Diamond Tiara is more of a Spoiled Sweet teen who wants to see the beauty of the world, only for her mother to keep her isolated from the rest of the world.  She dreams of breaking out of her only home so that she may see the world.  Little does she know, she plays a part in the rebellion against her mother.

Discord(Ideal Voice Actor: Scott McNeil or Vic Mignogna): The Guardian of the Everfree Forest, Spirit of Chaos, and a long time friend of Celestia.  He is also the surrogate father of Fluttershy, a timid pegasus who's afraid of stepping out of the forest.

Nightmare Moon: A Dark entity who was defeated long ago by Celestia and Luna.  Since her defeat, her physical form was split into a number of artifacts that contained a small portion of her power. It is said that Cinch is fusing these artifacts into Luna Della Notte to create a new Nightmare Moon.

One important change is that Canterlot is no longer the capital of Equestria.  This time, it's Maretropolis, a giant Magitek Mega City bustling with Pony activity.  CAnterlot and Ponyville returns, but serve as smaller cities this time around.

What are your thoughts on my idea?  What would you add to make this appealing?
