One plot idea could be that the pony-turned-dragon has to learn to control its new powers. It might accidentally cause destruction in its pony village at first, and then has to go on a journey to find a way to reverse the transformation or at least master its dragon abilities. Another could be that there's a magical curse that turned the pony into a dragon, and it has to find the source of the curse to break it. And perhaps in its dragon form, it discovers a whole new world of dragon-kind that has different rules and cultures compared to the pony world.
A plot could involve the pony-turned -dragon being shunned by its pony friends at first. But then, when a great danger threatens the pony land, like an evil sorcerer, the dragon's new powers are the only thing that can save them. So it has to prove its worth and gain back the trust of its friends. Also, the dragon form could give the pony access to memories or knowledge from long - ago dragons, which it uses to solve a mystery in the pony world.
Maybe the pony is turned into a dragon as part of a prophecy. In the dragon form, it is meant to unite the ponies and the dragons, who have been at odds for centuries. The pony-turned -dragon has to navigate the politics and prejudices of both groups. It could start by making friends with a young dragon who helps it understand its new body, and together they work towards the goal of peace between the two species.
