Moderated by Keely Flaherty of BuzzFeed, the panel included behind-the-scenes reveals, a brand-new trailer, and never-before-seen clips from the upcoming series.

Raph, Leo, Donnie and Mikey emerge from the sewers and tap into undiscovered ninja powers in Nickelodeon’s reimagined, 2D-animated series Rise of the Teenage Mutant Ninja Turtles, debuting Monday, September 17th. The action-comedy series follows the band of brothers as they discover new powers and encounter a mystical world they never knew existed beneath the streets of New York City. In the months following, the series will premiere globally across Nickelodeon’s channels and branded blocks in 170+ countries and territories.

Take a look at the brand-new trailer below, followed by an exclusive quote from super-villainous guest star Rhys Darby and a new look at the villains of Rise of Teenage Mutant Ninja Turtles in our gallery:

Here's what Darby had to say:

"As a kid I would run home from school to watch the greatest cartoon in the world. I can't believe that little ole me is now part of the TMNT universe. Finally, the magical kiwi hippo gets his day in the sun. What a pleasure it is to play him on TMNT! I've been telling people that New Zealand has magical hippos for years, maybe now you'll all start taking me seriously!"

Rise of the Teenage Mutant Ninja Turtles follows the Turtles on all-new adventures as they master new powers, encounter absurd mutants and battle bizarre villains, each with their own motivations. Ranging from mystics, mutants and madmen, new creatures and villains emerge to take on Raph, Leo, Donnie and Mikey in battles across New York City.  From the tallest skyscraper to the dankest sewer drain, the brothers learn to work together and navigate the perils of New York City and the hidden realms below in order to fulfill their destiny to become a team of heroes.

The line-up of guest stars voicing these new mutants and bizarre villains includes: Lena Headey (Game of Thrones) as Big Mama, a gigantic spider mutant; John Michael Higgins (Pitch Perfect) as Warren Stone, a former news anchor turned mutant earthworm; Tom Kenny (SpongeBob SquarePants) as Albearto, a singing, birthday-loving rampaging robot; Sam Richardson and Tim Simons (Veep) as Muninn and Huginn, gargoyles who are never far from their master, Baron Draxum; John Rotten Lydon (Public Image Ltd ‘PiL’ and Sex Pistols) as Meat Sweats, a power-hungry mutant pig; Rhys Darby (Jumanji: Welcome to the Jungle) as Hypno-Potamus, a mutant magician/hippo; and Jorge Gutierrez (El Tigre) as Ghostbear, a human pro-wrestler champion with a taste for cheating.

In addition, Rob Paulsen (Teenage Mutant Ninja Turtles) and Maurice LaMarche (Animaniacs) reunite behind the mic as Foot Lieutenant, the de-facto leader of the Foot Clan, and Foot Brute, the Foot Lieutenant’s right hand man.

In the half-hour launch episode, “Mystic Mayhem,” the Turtles discover for the first time that they’re not the weirdest things in New York. Fans can watch a sneak peek of “Mystic Mayhem” on Friday, July 20th, at 9:30 p.m. (ET/PT) on Nickelodeon. Additional episodes will be available on the Nick App, Nick.com, and Nick On Demand.
