Starting off,  let's introduce our main cast!  (Be aware I made there characters back when Season 6 was just airing,  so some details may be inaccurate)

Counting Stars,  the son of the Princess of Friendship Twilight Sentry-Sparkle and her Husband, Captain of the Ponyville part of the Royal Guard, Flash Sentry-Sparkle.  He's been homeschooled for the first 5 years of his life, and being born an alicorn prince, he was spoiled to death.  Of course, that won't stop him from being generous, but sometimes he forgets that he doesn't have people fussing over him anymore.  He's highly interested in Archeology, contradicting his name. 

Ruby and Sapphire (STEVEN UUUUNIVERSE),  children of successful fashionista Rarity and the first ever dragon model Spike,  were born twins, yet they're not your stereotypical same person or opposites.  They both love collecting gems together, but while Sapphire uses them for accessories,  Ruby tends to use them in her restaurant, which she runs with her girlfriend Tibia,  a changeling.

Next up is Fire Spirit.  He's an adventurous pony,  preferring to usually explore alone. 
He's the son of the Wolderbolt Rainbow Dash and Quibble Pants, a librarian in the library built in Memory of Twilight's old one. 
He has social anxiety and is therefore introverted.  He considers Tella a close friend,  but he would only hang out if asked to by her. 

Another child is Chaotic Neutral (changed her name),  daughter of Fluttershy who opened her animal shelter and clinic, and Discord, Former Lord of  Chaos and a stay at home Dad. 
She is currently studying psychology with all the resources she can find,  and is sort of a feminine tomboy.  She likes dressing up from time to time but wouldn't mind getting that dress dirty from time to time.

Second to last is Zap-Apple Jam,  the son of local apple farmer Applejack and now HONEST inventor of different kinds of gadgets, Flim. 
Zap loves to annoy or make people laugh with puns and jokes.
He wants to be in the Apple family's business.

And our last pony is my personal favorite, Straccatella Ice-cream, her first name being spelled like that due to a misspelling from Party planners Pinkie and Cheese Sandwich.
She suffers from ADHD that she might have gotten from her mother. 
Other than that,  she's usually way calmer than her mother, but still just as excitable.  She plans on taking on Party planning part time while working on a little coffee shop for snacks and ice cream across Ruby's Restaurant.

And here they are!  Welcome to my MLP Next Generation
