Speculation on his nature and build?
We all know Gen. Gorthoklek is a Pit Fiend. That's easy.
But what else is he?
Is he just an Advanced Pit Fiend (so CR 21)?
Is he an Infernal Duke?
Is he both?
Or is he a Pit Fiend with class levels? If so, what levels? Fighter 4 maybe?
Maybe he's an Advanced Pit Fiend Infernal Duke with a few Fighter levels.
Or is he something else?
Let me know what you think.
Right now, I'm just leaning toward an Advanced Pit Fiend, but perhaps I'm missing some important lore bits not covered in the Pathfinder Wiki.
