I originally had a standard GW LOTR Balrog as my Destroyer. I then swapped out the sword for a Defiler sword (inspired by a CDO post). The model’s final form as a ‘Balewind Balrog’ came about from stumbling across this battle report and subsequent model spotlight - highly recommend a read. As you can see from the first post, the Destroyer towers over the rest of the army.
I always liked the mention of the Hammer of Hashut in the army book fluff and wanted some terrain to speak to the Chaos Dwarf’s destructive machinations.
My Ogre Kingdoms army was started after the Slave Ogre for the Dreadquake Mortar had been finished. I decided to make them kin, hence the similar paint job. The lighter blue Ogres were the last to join the army, they were a bulk purchase from a guy in Queensland (the in-army fluff is that the blue progressively darkens with age).
The Hunter started life as a standard Ogre Bull, who one day picked up a partially destroyed Bolt Thrower (has also been a stand in Hobgoblin Bolt Thrower, or unit filler as required).
