Alan Grant

Alan Grant is a Caucasian man currently in his mid sixties, standing 6'0", with blue eyes and gray hair (brown in his youth). In Jurassic Park, Grant wore a long sleeved buttoned denim shirt, a brown belt, khaki pants, brown boots, a red bandana, and a palm leaf straw hat. He also at one point had a pair of sunglasses but lost them during the incident in the park. In Jurassic World: Dominion, Grant now sports a beard and the same hat from Jurassic Park III.

Alan loves dinosaurs and dedicated his life to digging up fossils and researching them. Although he cares about those around them, Alan was originally not a big fan of kids and found them annoying, despite once being a child himself. However, after bonding with Hammond's grandchildren, Alan's opinion of kids changed and he would become protective of children, ensuring their safety first in later events, as seen with Eric and Maisie. Also, Alan would help his friends in anyway he could, even in dangerous situations.

The events at Jurassic Park left Alan unhappy with dinosaurs as he lost the passion he had with them. However, after being forced to help Paul and Amanda find their son Eric, Alan rediscovered his love and passion for dinosaurs again. Unfortunately, Alan was still traumatized by the events of Jurassic Park as he developed a deep fear of raptors, because of this he was reluctant in accompanying Maisie and Owen in capturing Beta. Despite this, Alan was willing to put his fear aside to help anyone in danger or in need. Also, Alan was skeptical that raptors could be trained and he was reluctant to try Owen Grady's method of taming them. However, after witnessing Maisie seeming succeed using Owen's method, Alan was convinced and utilized it to aid in capturing Beta, which they were able to do.

Throughout the years of digging fossils, Alan became unhappy with his life, but his mood changed after he rekindled his relationship with Ellie, finding excitement again. Alan even decided to accompany Ellie, Ian and Ramsay to testify against Biosyn to put an end to their plans for good.

It is implied in the films that Alan dislikes Ian Malcolm, possibly due to Malcolm's eccentric nature. After Alan saves Ian from a fall next to the Giganotosaurus in Dominion, Alan seemingly looks past Ian's personality and they seemingly become good friends.
