Admiral Bobbery and Bombette, two Bob-ombs' Heroic Sacrifices become canon in a way, as in Paper Mario: The Origami King, Bobby, a Bob-omb partner pulls one in order to help Mario continue on his way.
This fanfic shows Rosalina having a Face–Heel Turn and wielding extremely destructive cosmic forces, years before Mario + Rabbids Sparks of Hope had Rosalina possessed by Cursa to create a cosmic life-eating threat to the entire galaxy.
They Wasted a Perfectly Good Character: Before he is freed, Koops is the leader of a group of ex-Glitz Pit fighters, who disappear almost as soon as they appear, with the exception of Rawk Hawk, who shows up at the end.
The first one is the eponymous "Fallen Kingdom", in the style of Coldplay's "Viva La Vida". It tells the story of a king reminiscing his days as the pious ruler who lead his kingdom in prosper, until Herobrine took over, freed the mobs, and spread them across the city, ensuing chaos and the kingdom's inevitable destruction.
The second one is "Take Back The Night", when they start to create their own original song. The song build up to a glorious hype, complete with the awe-inspiring Coming of Age Storyof the surviving son of the king.

Although, considering Herobrine is one of the leaders of the Piglin Army and is shown to have wanted access to the End, most likely to tame the Ender Dragon and use it to conquer the Overworld, it throws this trope into question.
The overarching villains of the series are living versions of Zombie Pigmen that heavily resemble the Piglins that would be introduced to Minecraft 5 years after "Dragonhearted" was released.
Related to the above, Mojang (likely unintentionally) took it one step further by announcing a spin-off game called Minecraft Legends, with the main plot being a Piglin invasion of the Overworld. The trailer even shows off a large Piglin akin to the one first seen in "Take Back the Night".
Tear Jerker: The end of "Dragonhearted". The son sacrificing himself by steering a Fantastic Nuke into the Piglin Emperor's castle, blowing them both up in the process.
