The final film in the Sharknado franchise, which aired on August 19, 2018.
Following the events of Sharknado 5: Global Swarming, the world is in ruins from repeated Sharknadoes. One of the only survivors, Fin Shepard, attempts to remedy this by traveling through time. He ends up traveling to various time periods and teaming up with old friends who were once lost.
Tropes
- Actor Allusion:
- Before shooting Billy the Kid, a cowboy played by Dee Snider screams “I’m not gonna take it anymore!” He also uses the phrase "twisted, Mister".
- Finn (played by Ian Ziering)’s parents in the 1960s are played by Tori Spelling and Dean McDermott. Not knowing that Finn is her son, she asks Finn whether they went to high school together.
- Darrell Hammond uses the same voice he used when playing Bill Clinton on SNL.
- Always a Bigger Fish: Fin gets threatened by a T-Rex, only for it to get eaten by a Megalodon.
- Back for the Finale: Some of the characters that were killed in the previous movies are back, thanks to Gil taking them from different points in time right before they were killed (in April's case, before she was put in a coma). In addition, once time is reset, Ryan Newman, John Heard, Gary Busey, Bo Derek, and Mark McGrath are at the bar.
- Breath Weapon: Morgaine enchants the sharks to breathe fire.
- The Cameo: Neil deGrasse Tyson as Merlin, Ben Stein as Alexander Hamilton, Darrell Hammond as George Washington, Dee Snider as Pat Garrett and more, per the norm.
- Call-Back: In the previous film, the older Gil uses the "Semper Paratus" Shepard family motto as a Trust Password to confirm his identity to Fin. This time, "Gil" appears from a time portal at a crucial moment and approaches Fin like before, but "he" uses the wrong motto, accidentally outing himself as a disguised future Robot April.
- Caught in the Ripple:
- Either none of the other characters notice that Bryan's career background changes between jumps - from physicist to history teacher — or else none of them can work up the nerve to mention it to him. Certainly he has no clue.
- While in 1997, Skye uses a handful of one dollar bills to pay for tickets on the charter fishing boat. Nobody notices that Bryan is now pictured on said bills.
- Chekhov's Gunman: The shark-fin fisherman from the opening sequence of the original film, whom most fans had written off as a pointlessly-dropped thread, not only reappears thanks to the final time-jump, but he makes good on his boast that sharks should be afraid of him. By having a stash of shark-killing heavy-caliber weapons, hand grenades, and a chainsaw of his own on board.
- Chuck Cunningham Syndrome: Despite being a major part of the film's story, and being shown making his time leaps in every era he visited, Gil vanishes from the film after the 1950s segment. It is shown that he surfed into the sharknado in an attempt to reach July 11, 2013, but by the time Fin gets there, Gil is nowhere to be seen. He is also not among Robot April's clones of her children, even though Nova is. Robot April appears in 2013 disguised as him, but what happened to the real Gil is never revealed. Following the Cosmic Retcon, April is pregnant with him, however.
- Close-Enough Timeline: Each journey forward results in changes to Bryan's (and only Bryan's) genetic and/or professional background. The others don't let it phase them, as Bryan is still similar enough to help them on their mission. After the Cosmic Retcon, Matt and Claudia suddenly have blond hair, but they're still the same people.
- Cosmic Retcon: Thanks to April's head self-destructing in the center of the shark timestorm, the explosion resets time and the events of the movies never happened. However, Fin and April never estranged and in fact conceived Gil sooner.
- Crosscast Role: Morgaine is played by a Drag Queen Alaska.
- Didn't Think This Through: Bryan chooses to stay in the American Revolution, believing he'll be happier there. Shortly after the group leaves, he asks the people around him for a burrito, and is horrified when they don't know what that is.
- Dinosaurs Are Dragons: Certainly the people in Morgaine's time seem to think Terra the Pterosaur is one.
- Double-Meaning Title: The title can refer to the movie involving time travel or that it's about time the franchise ended.
- Evil Is Petty: Morgaine attempts to exploit the Sharknado to take over Camelot, even after Merlin promised to give her Excalibur if she would help them stop it.
- Gender Flip: In-Universe, Bryan turns into a black woman, due to time travel.
- Giant Flyer: Terra, April's tame pterosaur.
- Go Mad from the Isolation: After being accidentally dropped overboard, Cyber April's immortal head spent Thousands of years at the bottom of the sea. By the time she was discovered, her shattered mind only wanted a family and was willing to do anything to get it.
- Grand Finale: Said to be the conclusion to the Sharknado series.
- I Choose to Stay: Bryan stays in the American Revolution. Though he ends up back in the present thanks to the Cosmic Retcon.
- Law of Time Travel Coincidences: The movie has a Time Travel plot where, in order to prevent Sharknados from occurring in the first place, protagonist Fin and several other characters who are brought Back from the Dead via Time Travel end up encountering Sharknados at various points in history, even meeting King Arthur, George Washington and Billy the Kid throughout their journey.
- Magic Versus Science: Morgaine uses magic while Merlin uses science thanks to Gil's influence.
- The Nth Doctor: Due to changes in the timeline, Bryan and Gil end up changing appearances a few times.
- Our Time Travel Is Different: A pre-recorded hologram of adult Gil explains to Fin that due to the instability of the energy used to time travel, an individual can only travel backward in time once and will disappear if they do so again. Fin later recalls this when he and Skye are trapped in the year 20013, but he is able to make it back to 2013 using Robot April's improved time machine.
- Pun-Based Title: The film's title refers to the fact that the film features time-travel, though can also be read that it's the last film in the series, and it's about time.
- Reset Button: At the conclusion of the film, Fin is able to change history so that the modern Sharknado storms never happened, undoing the events of the entire franchise but leaving his entire family alive.
- Rousing Speech: When they end up in the American Revolution and team up with the American soldiers, Fin gives a speech saying they are fighting for not just America, but humanity. However, the soldiers just stare at him confused.
- Sequel Non-Entity: Dolph Lundgren doesn't appear in this film, despite appearing at the very end of Sharknado 5 as Fin's grown son Gil and it being set up to look like they'll be in the sixth movie together.
- Set Right What Once Went Wrong:
- Fin tries to prevent the Sharknadoes from destroying the world through time travel.
- Nova sidetracks their journey through time with the intent to save her grandfather's life.
- Several unintentional improvements also occur: an earlier mending of Fin's and April's marriage, Gil Sr. remaining a professional astronaut, and Skye being favored to become the next President of the United States.
- Shout-Out:
- Fin slides down a T-Rex's tail a la Fred Flintstone.
- Morgaine screams "I'm melting!"
- Morgaine uses one of her actresses catchphrases, “Byeeeeee” when disappearing.
- Fin's time machine wingpin requires him to be accelerated to 88 miles per hour in order to work. Nova also attempts to write a letter to her grandfather to warn him only Fin to tear it up and for it to be taped back together by the time her grandfather actually receives it.
- Just like how Deadpool references the Sharknado series, Fin does the same the other way around.
- Stable Time Loop: Nova's attempt to save her grandfather only results in her causing the boat crash that led to his death in the first place.
- Time Crash: In the climax, Fin and Robot April fighting over the capacitor in the first/last sharknado causes this.
- Time Traveler's Dinosaur: Fin Shepard attempts to prevent the destruction caused by the Sharknadoes by traveling through time which causes numerous numerous being from history and even mythology to appear including several examples of this trope, most notably a Pterosaur and T-Rex.
- Utopia Justifies the Means: Robot April spent 20,000 years to create a stable time machine so she could create a "utopia" for herself, Fin and their family. Unfortunately, to her, utopia means becoming a clone and ruling a ruined planet for eternity.
- What Happened to the Mouse?: The Cosmic Retcon establishes what became of nearly all Fin's friends and family in the new sharknado-free reality ... except Baz from the first film, whose absence from Fin's bar is never explained.
- Where It All Began: The last scene of the film, and the series, takes place in Fin's bar from the first film, but without a sharknado in sight.
