Here's an idea for the 5th Generation of My Little Pony, now just bare with me for a moment -



In an Alternate Reality, for centuries the Country of Equestria lived with a Human-like society where the population has been with Equines(more specifically Ponies) in place of Humans, and for the longest time Equestrian Citizens were only aware of the existence of Earth Ponies, Pegasi, Unicorns, Alicorns, Donkeys & Mules, but after Ponies began exploring other countries around the world, they started discovering New Species of Equines that they never even knew existed before, and wanting to forge new friendships with these Foreign Species of Equines, Princess Celestia(or whoever would take her place in the next Generation) began the "Equinial Cultural Exchange Act", where these various other species of equines would be brought in to become a part of Equestrian Society, living with other ponies like foreign exchange students and au-pair visitors, provided that they all become beneficial attributes to Equestria Society(in other words Not just a bunch of Freeloaders), and years pass by since then, and Earth Ponies, Pegusi, Unicorns, Alicorns, Donkeys & Mules have for the most part adjusted to having various other species of Equines living among them, which in turn would make this 5th Generation of MLP have similarities to the 'Monster Musume' franchise, this way the Next Generation of MLP's Main Cast would have much more diversity among them,



like for the Next Generation, the Main Cast could be composed of Equines like:



A Zebra - who is training to be a Shaman(similar to Zecora), but she's still a young naive who has a much to learn about Mojo Magic & Potion Making before she can become a Full Shaman.



A Longma - aka a Dragon-Horse, a Winged Pony that's Half-Dragon(on a Genetic Scale, not a Fractional Scale), she's a Strong Flyer, she can breath Fire, and can withstand intense Heat, but she tries to avoid Water & the Cold, because Water puts out her Fire-Breath, and the Cold slows her down & makes her get Cranky.



A Kelpie - one of many different sub-species of Water-Horses, a 4-Legged Pony that's Half-Fish(on a Genetic Scale, not a Fractional Scale), she has both Lungs to breath Air, and Gills around her neck to breath Underwater, she also has Hydrokinesis(Psychic Ability to Summon, Control & Manipulate Water with her Mind), but she needs to constantly splash water on herself to keep herself & her Gills Moist so that she can survive on Dry-Land, she can withstand intense Cold, but if she's exposed to Intense Heat(like Fire) or even Salt, it causes her to Dehydrate faster than normal.



A Flutter-Pony - basically a Pegasus that has Magical Butterfly Wings instead of Bird Wings(based on the G1 MLP characters by the same name), she can fly Faster & more Agile than Pegasi, but she's not as Strong a flyer as Pegusi, her wings are fragile, but they regenerate at a very fast pace, they can also glow by generating a magical energy, and she can unleash powerful Energy Waves by Flapping her Wings, her kind also have stronger connections to animals than any other species of Equine, so she can natural communicate with Animals & persuade them to help her out.



A Bat-Pony - basically a Pegasus with Bat-like Wings & Attributes(this one especially has a few "Bats" in her Belfry), she has ultrasonic hearing so she can hear incredibly well, she can also see in the Dark so she mainly wears Sunglasses during the Day, she also has a Sonic Screech Attack that if she screams at the top of her lungs she can shatter even a Diamond, Bat-Ponies are normally Nocturnal, but this one is so social that she likes stays up during the day to be with others, and she has a condition where she's mostly hyper-active, but if she's in a position where she's turned Upside-Down, she gets drowsy & is more likely to fall asleep, which often times causes her to get into some pretty humorous situations.



and last but not least, the Main Focused Character of the new generation....



A Twonicorn - basically a Unicorn that has 2 Horns instead of just 1(aligned with 1 in front of the other), because Twonicorns have a Stronger Connection to Mystical Forces than any other species of Equine, they are basically more powerful than even Alicorns, but this one is still young, and has yet to uncover her True Potential, her kind is also the most recent new species of Equine to participate in the Equinial Cultural Exchange Act, so most of Equestria doesn't even realize that she is more powerful than even Celestia, so they tend to underestimate her, for a few years now she has been staying with Celestia as a student, to learn more about all the other kinds of Magic that exists in Equestria & beyond, but Celestia feels that she needs to get out & explore more of Equestria if she is to gain Experiences rather than just Knowledge, so Celestia sends her to Ponyville, where she encounters the other 5 Main Characters, and they all forge a Strong Bond with one another.



And together, they have great adventures, using each of their own unique attributes & abilities to overcome various obstacles, and aiding each other in their times of need, and since they are all different varieties of Equine Species, they all stand out among Earth Ponies, Pegusi & Unicorns, which gives them all the feeling that they don't really fit in with Equestrian Society, despite the fact that they are for the most part still excepted by the other ponies, That would sound like a Decent Idea for a 5th Generation of My Little Pony to me, so what would You think about That Idea for G5 MLP?
