Well, in some fictional works, the Grabber's back story often has elements of isolation. He might have been an outcast in society, not fitting in with others. This sense of not belonging could have festered over time, and combined with other factors like mental illness or a series of bad events in his life, ultimately made him into the Grabber. For example, if he was bullied as a child, it could have planted the seeds of his later violent tendencies.
Yes, 'The Grabber' is based on a true story. It often draws elements from real - life events or situations which gives it an air of authenticity and makes it more chilling as it reflects something that could potentially have occurred in the real world.
You could also develop its character based on its experiences with the environment. If it has to struggle to find food in a certain area of Jurassic Park, it might become more resourceful and determined. It could start to explore new areas and develop a sense of curiosity about its surroundings.
The relationship can be developed through mutual need. For example, if the human is lost in the dinosaur's territory, the T - Rex could initially see the human as prey but then realize the human has some unique skills, like making fire or using tools. This could lead to a truce. Or if the T - Rex is injured, the human could use their medical knowledge (assuming some sort of knowledge transfer in the story) to help the T - Rex, and in return, the T - Rex protects the human from other threats.
Well, here's a story. There was a lonely T - Rex. One evening, as the sun set, he met an old wise turtle. The turtle told him stories about how important sleep was. The T - Rex was intrigued. That night, as he lay down, he thought about what the turtle said. He realized that he needed to rest just like all the other creatures. So he closed his eyes and had a peaceful sleep. This shows that even a big and strong T - Rex can benefit from a good night's sleep.
Once upon a time, there was a little T - Rex named Timmy. At bedtime, Timmy didn't want to go to sleep. His mother told him a story about the brave T - Rexes of the past. She said that long ago, their kind ruled the land. But they also knew when to rest. As she told the story, Timmy started to feel sleepy and finally closed his eyes.
