As far as trailers go, final ones for films are usually relatively lackluster compared to the first, second, and even third ones.

Warner Bros. dropped the final Fantastic Beasts sequel trailer on Tuesday, revealing the footage on Twitter and broadcasting live fan reactions on electronic billboards in New York City, Toronto, and Tokyo (via Variety). So he enlists the help of his former student Newt Scamander (Eddie Redmayne) to help take down the powerful Dark wizard, along with his band of followers.

The sequel to 2016's Fantastic Beasts and Where to Find Them, The Crimes of Grindelwald once again follows naturalist Newt Scamander as played by Eddie Redmayne, but it will be hard for even the franchise's central character to not be overshadowed by both the villain and the returning presence of the beloved Albus Dumbledore. Meanwhile, Grindelwald is trying his means to pull wizards out and use their power to rule the world. What will do that, however, is the moment Credence Barebone, played by Ezra Miller, utters "Nagini".

Now, if you're asking yourself how a flesh-and-blood human being could also be a snake, "Harry Potter" fans have already done most of the heavy lifting. If only the Niffler had killed Nagini in her snake-form in the 1920s. "Everyone is so good at analyzing every element there is".

This reveal seems very Anakin-built-C-3PO to me. South Korean actress Claudia Kim is bringing the fictional character to life. "She does feel sometimes it's not controllable", Kim says. And oh, Potterheads, here's some interesting news for you, remember Nagini?

Following the release of the trailer, Entertainment Weekly has confirmed that the shape-shifter Nagini, who eventually becomes Voldemort's Horcrux, will be joining the franchise. We get a look at a woman in a circus who then turns into a snake, and not just any snake, it's Nagini.

Fantastic Beasts: The Crimes of Grindelwald - which also stars Zoë Kravitz, Callum Turner, Claudia Kim, William Nadylam, Kevin Guthrie, Carmen Ejogo, and Poppy Corby-Tuech - opens on November 16.
