The final trailer has been released for Sharknado 6, and it teases what may just be the most outrageous shark movie ever made.
The video features dragon sharks, a robot shark, a shark riding a surfboard along the beach and even a giant shark killing a Tyrannosaurus rex.

"In the ending moments of Sharknado 5: Global Swarming, Fin was seen wandering alone on Earth after it was destroyed," says SyFy, distributor of the Sharknado films.
"Now he must travel back in time to stop the Sharknado that started it all. Will Fin and the gang be able to set everything right and save the world once and for all?"
The time travel plot appears to be echoing Transformers: The Last Knight and Bill & Ted's Excellent Adventure, with the main characters fighting sharks in Merlin's Castle, with cowboys in the Wild West, with Benjamin Franklin and in a dystopian future.
Fin, played by Ian Ziering, also fights Nazis and takes a ride on Noah's Ark in the film.
The sixth main movie in the cult franchise is officially titled The Last Sharknado: It's About Time. It was released in the US on August 19.
