Grug Crood is the main protagonist of DreamWorks' The Croods franchise. He is 39 years old caveman and is the father figure of the family. Grug has dark brown hair along with a scruffy beginning of a beard. He has hazel eyes and has very big teeth. He wears a brown fur of possibly a bear and is heavily built, and very tall with muscles and a muscle belly. Grug is the father figure of the Croods. He is incredibly overprotective and worrisome of his family (although given the environment they lived in this was somewhat justified) who sticks very strictly to his motto "never not be afraid". Grug was also shown to have a violent temper and relied on brute force more than quick-thinking. Although he wasn't stupid, he still showed signs of being somewhat dim-witted as evidenced when while Thunk was trying to escape from the fire, Grug suggested he hides from it in the grass which unintentionally caused it to spread. However, he still showed some common sense which was shown when Guy escaped and he stood on sharp rocks he urged his family not to do the same (which they did). Grug appeared to be anti-intelligent and thought that caveman didn't need brains as long as they had their brawn. During the film, he had also been outsmarted by animals like the Macawnivory and monkeys in the jungle. It's not until near the end where Grug shows that he is actually quite intelligent and cleverly used the Piranhakeets to escape his own demise. Grug has has also shown tremendous physical strength, being able to move a heavy boulder by himself and was able to throw his entire family over a gaping chasm. However, he was still strategic enough to not take on opponents he knew he could not defeat such as the animal that stalked his cave and would either throw rocks or hide from them. Despite Grug's anti-intelligence he was still creative enough to think outside of the box and have his own ideas such as the self-tightening belt, a rug (which is essentially a wig) a ride, the mobile home, shades, a snapshot and the lifterator which granted actually caused him and his son massive physical pain. Grug also shared some similar qualities with the stereotypical father, he generally dislikes his wife Ugga, his three children, Eep, Sandy, and Thunk. His wife for no reason other than being slightly naggy. His kids being annoying. He has quite a misogynistic, sexist and old fashioned mind set. Grug and his family speak in stereotypical caveman speech. With some unga bungas in there.
