How tall do you think the trolls are, both younger and fully grown? Also, does height have alot to do with blood color? Thanks for reading!
Hussie is very weird with sizes, with various styles and a disregard for heights in general, every Kid and Troll seems to be designed to be the exact same height in his style- But much like the skin tone of the Humans, Height and a lot of the time, Body Type, is left up to the reader’s imagination. In sprite form, I believe Condy is about the same size as the Adult Humans, but her height has also fluctuated from being slightly taller than Aranea, to her horns being as tall as Roxy herself is. Soooo, pretty much up to you?
That being said, there is ONE solid show of height differences I can recall from the Ancestors Stories, and…

Given Psiioniic is taller than the Disciple, and Dolorosa is taller than all of them, it’d seem that heights just sort of depend on the Troll like they do with Humans. You could argue Higher Castes being taller, but ultimately, it’s a Headcanon.
Also the height difference could be a result of age, maybe Disciple is the Youngest of the Four, and Trolls just sort of. Keep getting taller with age.
