so is "His Honorable Tyranny" a troll or a monster? and if it is justt a random monster, why implement it into the Alternian justice system?

It’s a Monster or perhaps a Lusus of some kind. We don’t really know much about him, other than the Drones and Condy’s ship really look like him, and that his blood is Black. Maybe he’s the base from which all Drones are made, or perhaps he’s the ‘male’ counterpart of the Mother Grub? Like, the Mother Grub being a Lusus that gives Birth to all Trolls on Alternia, the Mother of the Trolls, while His Honorable Tyranny would be a Figure of Authority that keeps the Alternian Judicial System in check, the Guardian of the Trolls.

This is all just speculation though, for all we know he’s just a security measure so Trolls don’t go killing each other in court.
