Family Member Clone

Why does my great-granddad look just like me but older and with glasses?

For some strange reason, western animated TV shows want us to believe that genetics works by having far distance relatives to the main characters, either in the past or future, look almost just like them but with minor changes such as clothes and accessories being appropriate to whichever time period they're in. But that's not how genetics works.

A Family Member Clone could be an ancestor or a descendant of a main character. This mainly only happens in stories from the past or future so that we know this other family member is related to their respective main character.

Two similar roles are Alternate Universe Clone, which is the same thing but for characters who aren't related by blood, and Alternate Timeline Clone, where characters are older or younger versions of their present day selves, likely in spin-offs or Time Travel stories.
