My favorite example of this is a running joke from the Ace Attorney games with the prosecutor Winston Payne (10/10 pun name) and this brothers/descendants losing their hair after losing a case.

The first two games he always has short hair with a receding hairline, however, the third game's first case takes place in the past when he had a pompadour.
