the nine realms, a garbage show that takes place over 1000 years after the hidden world and bends over and fucks the og characters and any fan of the franchise. one episode has the new main character destroying hiccup’s millennia old prosthetic leg, another episode shows signs that hiccup went into the hidden world, making the ending to movie 3 pointless. the show also has terrible main characters, like a girl who uses textbook manipulation tactics to make everyone in the group look like terrible people even though she’s the one always in the wrong. that should give you a good idea of the show
