Trolls

ghastly creatures covered with boils. their ugliness is proportional with their violence, lashing out at anything they consider ugly (their view of beauty is a mirror of the truth) and see themselves as the most beautiful. even when their looks seem contradictory they are all very strong capable of lifting humans like they're dolls, in addition all trolls are able to heal from death and shrug off injuries as if they're love taps

Culture

Forest Troll

forest trolls are the most common troll they are commonly considered a greenskin even though they are not moss-men like other greenskins. the only reason they would serve in greenskin ranks is under special circumstances and even the most influential and powerful ork-boss still may never have had a troll serve him.

forest trolls have limbs that are long and skinny, the limbs are easily double the size of the head and abdomen so a troll standing strait up is capable of massive heights of 14-18' but since they walk with their ankles to their hips their heights are normally much shorter. despite their size forest troll are surprisingly dexterous capable to dodging attacks even in tight corridors. 

troll are notorious for their cruelty and selfishness. when attacking a group a troll will prioritize eating those that would induce grief and horror in those still alive before moving on and even when they end up helping greenskins trolls have a tendency of killing and eating their 'allies'

Cave Troll

Also referred to as 'trogres' or 'ogrlls' they are seen as a hybrid of the ogre and the troll (even though they aren't) they arent as violent as a normal troll due to their heightened idiocy but have all of the regenerative capabilities and double the endurance since their skin is practically made of stone.

Cave trolls are similar to green ogres in the fact they both have extremly powerful stomach acid that can eat through steal and both dont mind pouring the corrosive liquid from their mouth in order to attack.

cave trolls breed very slowly but killing one is next to impossible with their only weakness being  turning to stone in direct sunlight
