These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The Dark Dragon is also a nasty piece of work. While he has much less screentime than the Huntsman, he makes up for it with the sheer scale of his evil. He basically wants to corrupt all magical beings and wipe out humanity. There's a reason the rest of the dragons consider him the Big Bad and not the Huntsman (though Jake and the Huntsman have a much deeper personal grudge).
Just an idea of how horrible the scales are: On a list dedicated to the 13 most evil beings in the Magical World, The Huntsman is only listed as #4, with the Dark Dragon taking the #1 spot.
Jonathan gets one in "The Long Weekend" and later in "Bite Father, Bite Son." The normally bumbling human dad fights to protect Jake from the Jersey Devil and vampires, respectively. He later helps save the day in the series finale as well.

As well as Huntsboys #88 and #89. Veered into Creator's Pet territory after the Hunstmen as a whole were killed off, but the two continued to appear anyway. Though they quit being Hunstmen at the last minute and weren't real Hunstmen in the first place.
Tear Jerker: The entire ending of "Homecoming". The ending of "Ski Trip" as well.
