Why did the rhinoceros mutiny in the second part of Monster Man?

In the second part of "Demon Man", rhinoceros defected because rhinoceros has its own ambitions. After the fire of rhinoceros was taken away by Tyrannosaurus Rex, it was transplanted to a new body by Tyrannosaurus Rex, which was the later tank chariot. Tyrannosaurus rex was worried that it would defect, so he tampered with its memory. However, due to the efforts of chimpanzees and others, tanks and chariots gradually remembered their memories as rhinoceros soldiers.

The character and ability of rhinoceros in Monster Man II

If it weren't for personality factors, rhinoceros would definitely be the leader of the leading party. Although the rhinoceros warrior is calm and doesn't like to take the lead, he always plays a vital role in some big events, especially driving a spaceship into a Tyrannosaurus rex that has evolved into a dual attribute, which won us a favorable time to return to the electronic star, but the final blackening was somewhat unexpected, perhaps because he was tired of the war and recognized the peaceful values of Tyrannosaurus rex.
