The Challenge: War of the Worlds -- coming soon to the streaming service -- will feature players from the United States, Australia, United Kingdom and Argentina with new series in the aforementioned different countries. The two-part tourney will feature "the biggest reality athletes battling it out to be named their country's champion."

Winners from four new Challenge series (The Challenge: CBS (working title), The Challenge: Argentina, The Challenge: Australia, and The Challenge: U.K.) will advance to the global tournament, The Challenge: War of the Worlds, and battle for the first-ever title as the Challenge World Champion.

Shortly after Season 38 of “The Challenge” wraps on MTV, “The Challenge: World Championship” will debut over on Paramount+. The competition series is set to premiere on Wednesday, March 8, with back-to-back episodes available in the U.S. and Canada. The following day, it will drop in the U.K., Latin America and Australia. It will be available in Germany, Switzerland, Austria, Italy and France on Wednesday, March 15.

“The Challenge: World Championship” cast will include both winners and MVPs from “The Challenge: Argentina,” “The Challenge: Australia,” “The Challenge: U.K.” and “The Challenge: USA.” Although no one from the MTV flagship participated in the international seasons, “World Championship” will incorporate the original show: Each competitor will be paired with a “Challenge legend.”

Per the press release, “They will help them win power, politic and avoid elimination in order to make it to the most difficult challenge of them all, the brutal finale worth $500,000. In the end, only the most dominant will conquer the game and prove they are not just the best in their home country, but the best in the world.”

Longtime host TJ Lavin will return as a co-host alongside global hosts Brihony Dawson (Australia), Mark Wright (U.K.) and Alejandro “Marley” Wiebe (Argentina).

The full cast will be announced within the upcoming weeks. Danny McCray and Sarah Lacina won “USA” while Kiki Morris and Troy Cullen won “Australia.” Winners for “Argentina” and “U.K.” have not yet been revealed.

“The Challenge” debuted in 1998 and has always focused on bringing back cast members from past shows. That began with former “The Real World” and “Road Rules” members and has since expanded to more than 27 other outside franchises, including “Are You the One?,” “Big Brother” and “Survivor.” Last year, Paramount+ announced the international seasons to take place in Argentina, Australia, U.K. and the U.S. — all of which will affect future seasons of the flagship show, which has been renewed through Season 39.

“Often, we would have people from other countries on and they had never seen the show,” Bunim/Murray president Julie Pizzi told Variety in June. “Now, all because of Paramount+, the cast members all over the globe are able to watch it and study it. They’re going in knowing who Wes Bergmann is or knowing who Johnny Bananas is, which is really fascinating.”

“The Challenge: World Championship” will be 12 episodes. Executive producers include Pizzi, Justin Booth, Dan Caster and Leanne Mucci with German Abarca, Ernesto De La O, David Sambuchi, Kristopher Schwalenberg and Brad Tiemann as co-executive producers.

Worlds will collide when The Challenge‘s ultimate global championship kicks off, and now we have our very first look at the chaos to come.

The Challenge: World Championship (which premieres on Paramount+ Wednesday, March 8 with two episodes; watch a first look video above) will pair MVP’s from its USA, UK, Argentina and Australia installments with Challenge legends from MTV’s past to form some of the most iconic teams in franchise history. Together, the duos will battle each other in hopes of coming out on top and winning the $500,000 prize. (And the World Champion title? That’s not too shabby either.)

The legends returning to the fold include Amber Borzotra, Darrell Taylor, Jodi Weatherton, Johnny “Bananas” DeVenanzio, Jonna Stephens, Jordan Wiseley, Kaycee Clark, KellyAnne Judd, Nelson Thomas, Nia Moore, Theo Campbell, Tori Deal, Wes Bergmann and Yes Duffy.

As for the first batch of global players, Ben Driebergen, Danny McCray, Justine Ndiba and Sarah Lacina will represent The Challenge: USA, while Emily Seebohm, Grant Crapp, Kiki Morris and Troy Cullen will be the faces from Australia. Contestants from the UK and Argentina series will be announced at a later date.

Fans can meet the global players by watching the international shows, which will be arriving soon to Paramount+. The Challenge: Australia begins streaming Wednesday, Feb. 15 (today!) at 1/12c; The Challenge: UK will drop Saturday, Feb. 25; and The Challenge: Argentina will release Wednesday, April 5.
