Canon couple refers to a pair of characters from an official franchise, who are traditionally considered lovers; no fan characters and such.
A couple is canonized when the partners are explicitly stated in the original work to be or have once been in a relationship OR implications of a relationship are affirmed by the creator or an otherwise highly-involved writer, director, or producer. This may only apply to certain adaptations, as two characters may become depicted as a couple in one official work but not in another.
Bonbon (MLP) Γ Lyra Heartstrings (MLP) β While these two have been a long time fanon couple, LyraBon was canonized in the final season of their series with a marriage proposal and wedding.
Donald Duck Γ Daisy Duck β The character of Daisy Duck was created as a love interest for Donald Duck and has since been depicted romantically for over eighty years of Disney media.
Bea Santello Γ Mae Borowski β Creator Scott Benson confirmed Bea as straight, meaning she would not pursue a relationship with Mae, who is just a friend.
Felicity Parham Γ Richard Watterson β Felicity hates Richard's wife and their family; the only romantic context ever seen between these characters in The Amazing World of Gumball was a non-serious instance in "The Shippening", an episode parodying shipping culture.
Judy Hopps Γ Nick Wilde β The WildeHopps ship is the predominant Zootopia ship, even teased by co-director Rich More and encouraged by Nick's voice actor Jason Bateman, but Judy and Nick have not been outright said to date by any official media or creator statements.
