The best example would probably be most of the star wars movie titles phantom menace, attack of the clones, revenge of the sith, return of the jedi, rogue one, empire strikes back, and the last jedi just to name a few.
The termninator movie series comes to mind also. the title have 2 parts instead of 3 like start wars Terminator 2: judgement day, Terminator 3 rise of the machines.
Lastly have to mention what i seen that made me post this question the Ace combat video game series. Yes I am a fan of the series and i seen a youtube video for ace combat 7 with the proper title in the thumbnail. but the title mentioned the "extra words" from Ace Combat 5 title
Ace Combat 3: Electrosphere Ace Combat 4: Shattered Skies Ace Combat 5: The Unsung War Ace Combat 6: Fires of Liberation Ace Combat 7: Skies Unknown
what is the term for the second part of the title?
