'America's Got Talent: Fantasy League' Trailer Teases Cutthroat Competition Between Judges (Exclusive)

TheAmerica's Got Talent judges are getting their own skin in the game as the competition heats up for America's Got Talent: Fantasy League. In NBC's latest franchise spinoff, Simon Cowell, Heidi Klum, Howie Mandel and Spice Girl Melanie Brown each draft their own all-star team of performers and face off against each other in the hopes of leading an act to victory.

ET has your exclusive first look at the full-length trailer for the new show, offering a sneak peek at the 40 awe-inspiring acts -- all fan-familiar AGT alumni -- that will be featured in the upcoming season. Fantasy League marks the first time within the AGT universe that the judges will also serve as mentors, overseeing their respective dream teams' rehearsals and offering suggestions and guidance in an effort to ensure that one of the 10 acts from their team is crowned victorious at the end of the season. While the winning act will score a grand prize of $250,000, the judges are seeking highly coveted bragging rights.

That's incentive enough to cue some serious trash-talking among the crew.

"Let the games begin!" an excited Mel B declares.

"My squad is better than your squad," Howie says at one point, prompting a fired-up Heidi to retort, "My team is going to crush you, Howie!"

Of course, the returning competitors are bringing a top-tier level of eye-popping performances to the stage -- complete with high-flying feats, pyrotechnics and more.

Also returning to AGT is the Golden Buzzer, which will come back for the qualifiers and semi-final rounds as an option for sending acts straight ahead to the finals. But this time, there's a twist -- the judges can use their Golden Buzzer for their own act, or to steal an act from another judges' team.

Each performance will be voted on by a studio audience to determine who advances to the semi-finals and final rounds.

"I think Heidi's very competitive, but then so is Simon, so is Howie," Mel previously told ET of her fellow judges. "I think we're all really competitive, to be honest, because we get to mentor them and we get Golden Buzzers, and we get to snatch and take each other's acts."

As for Simon, Mel, who previously worked with the British judge on The X-Factor, jokes, "He says the most annoying things to me. He's adorable, but he's annoying."

America's Got Talent: Fantasy League premieres on Monday, Jan 1 at 8 p.m. ET/PT on NBC, streaming the next day on Peacock.
