Star Trek's United Federation of Planets by series.
Enterprise: Why don't we make a federation?
TOS: The Federation is cowboys and aliens.
TNG: The Federation as it sees itself.
DS9: The Federation as others see it.
Voyager: We're hitchhiking back to the Federation.
Movies: The Federation made some oopsies.
LD: The Federation's brochures exaggerated.
Picard: Well, things can't get any worse for the Federation...
Discovery: And then things got worse for the Federation.
I left out TAS due to space, but it's basically underappreciated and "Discount TOS" at the same time.
