Since I'm not sure precisely what 'mlp the real story' entails, it could potentially be a story that reimagines the entire My Little Pony universe. It could start from the very beginning, giving a different origin story for Equestria. It might explore how the different elements of harmony were truly discovered and the sacrifices that were made along the way. It could also look at the ponies' society from a more critical angle, examining power structures and how they impact the lives of individual ponies. There could be a focus on the economic aspects of the pony world, such as how they trade goods and services, which is something not often covered in the normal My Little Pony shows.
The 'mlp the real story' might be a story that adds more depth to the characters in My Little Pony. For instance, it could show Twilight Sparkle's journey in a more complex way, dealing with internal struggles that the regular show doesn't fully explore. It could also introduce new villains or challenges that the ponies have to face, perhaps ones that are more relatable to real - life issues. It might even change the way we view the relationships between the ponies, like the friendship between Pinkie Pie and Rainbow Dash, by presenting a different side of their bond.
I don't have a lot of information on 'mlp the real story' specifically. It could be anything really. It might be a new and unique plotline that someone has created based on the My Little Pony concept.
