Also, I've seen some people already talking about that, but THP felt very parallel to TDP?
Spoilers to THP plot below!
The villain is an angry, self-obsessed Skywing queen, cruelly ruling her tribe
Secondary villain, equal in power to her, is a bit quiet, intimidating, scary character often shipped with her.
Main character is a Mudwing that loves his siblings very much, doesn't feel like he's anything special or fit to the role he's given.
His main love interest is a slightly socially awkward, red dragon, could say a dragonet of the main villain Skywing queen. Their tribe has very strong feelings towards them and they have a very special power their parents take advantage of
The main character dethroned the main villain with the help of their loved one and acid-spitting rainwing
And possibly more, those just are the firsts I thought of
