Greg

Greg was a man camping out at Big Rock National Park. He owned a crossbow, which he taught Kadasha how to use, much to her father Dennis' displeasure. When a group of Nasutoceratops invaded the group's campsite, Greg hid in his camper van. This ended up saving his life when an Allosaurus appeared and attacked the Nasutoceratops family, then turned its wrath on the trailer with Dennis' family inside. But thanks to Greg teaching Kadasha how to use his crossbow, she was able to retrieve it and use it to drive the Allosaur away. Greg was last seen timidly emerging from his camper to survey the damage.
