: I can now confirm this - the hulks are switched to native beasts on TC.
Ok, I've spent the last half hour or so studying this. It seems that the native beasts (the shapes file calls them gargoyles) are positioned in the Physics file as though they were Major Hulks. They have a vitality of 2000 and a melee attack set to "Major Hulk Slap". The Minor Hulks are in their usual position and have the usual physics associated with them. So doesn't that mean on the easier difficulty settings, PF will treat and show this enemy as a normal Minor Hulk, but on the higher difficulty settings it will treat and show them as though they were a Major Hulk, so hence a native beast?
