Yeah,but until now we only have saw male black goblins,maybe beetween them,females are smaller,as we saw,the average female goblin have the same size the males,save some cases as we saw Brute being a plus size goblin,what we do know is that female goblins are naturally sturdier and stronger than the majority of the male pool of the race,but Shakala never mentioned nothing about a black goblin female appearence before,she only mentioned them as a distant tribe,most of the details about them come from Frida(which isnt exactly an scholar or researcher about the species in case)...
