In the light novel, Ayanokoji is clearly the more intelligent one. He has a unique ability to analyze situations and people's motives deeply. Ryuen often falls into Ayanokoji's traps because he doesn't fully understand Ayanokoji's true nature. Ayanokoji can anticipate Ryuen's moves and counter them effectively, while Ryuen struggles to keep up with Ayanokoji's complex thinking.
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, a funny T-Rex cartoon often has a combination of elements. Maybe it's the goofy situations the T-Rex finds itself in, or the comical way it interacts with other characters. Sometimes, it's the simple and wacky design of the T-Rex that brings the laughs.
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.
