While most girallons are little more than beasts, ancient carvings and the oral traditions of some tribes hint that the girallon wasn't always the stupid creature it is today. According to these legends, the first girallons were men who called upon savage demon gods to gain great strength, yet in so doing abandoned their humanity. With each generation, these first girallons grew more and more savage and feral, and the same legends maintain that these intelligent girallons still dwell in the darkest part of the jungle.
