All of the main and recurring characters have changed as the series has developed over the years.
Adam West has remained the same.
Mort, Muriel & Neil Goldman have also remained the same, mainly due to their lack of use.

When a character changes throughout the story is called a dynamic character and when a character does not change throughout the story is called static character. In Macbeth , Macbeth starts out as a good honorable guy and then he changes to a completely different person. He starts killing people so he could become king. Macbeth's wife could be considered a static character. Since the beginning she seems to be selfish, evil and power hungry.
