With The Challenge 40 almost ready to pack up after its finale on January 1, 2025, MTV has announced a new spin-off season. Titled All Stars: Rivals 5, the season hit the small screen on January 29, 2025. Fans were all geared up for a thrilling new chapter, but the excitement quickly turned into disappointment when MTV announced the cast lineup of the new season of The Challenge. Returning this season will be 26 former contestants from the franchise, including 10 men and 16 women who battle for the big win.The Challenge fans react to All Stars: Rivals lineupThe Challenge fans have flooded social media expressing disappointment with the new season's lineup.A fan on X wrote:"First time in a long time I have NOT been excited for a season, I mean was NO ONE ELSE available? These are like the season 40 rejects. Awful awful cast, except for Ashley M. They could have kept this one."Another post on the social media platform read:"Okay not to be rude but this is the most nothingburger cast I have ever seen. Was everyone busy or something? There are some interesting players but it’s just…I don’t know #TheChallenge.""I don't think i could possibly pick a worst cast. I mean I thought 39 cast was the worst but this one blows it out of the water. Literally every person I can't stand on one season. Only bearable ones to me is Steve and Kelly Anne. The rest 🤮🤮🤮🤮,"wrote another fan of the show.A netizen commented on his account:"Soooo disappointed. The all stars spin off should bring some nostalgia back for all the die hard fans who have been watching since their childhood. They did well for a few season, but what the hell is this?! There's even people on it who have literally been on 1 single challenge."A fan called out the producers for repeating the same cast members:"I really wish they cast actual all-stars on the show called All-Stars. The idea of this spin off was SO GOOD but the execution is crap. The same people who cast for The Challenge must be casting for this too.""Great idea bringing this theme back but why do people being regularly casted on the main show have to now be on all stars too? Talk about over saturated,"read another fan's post.The Challenge All Stars: Rivals - Cast Lineup View this post on Instagram Instagram PostHere is the cast of season 5 of The Challenge All Stars: Rivals:Adam Larson and Steve MeinkeAmber Borzotra and Faysal Shafaat (Fessy)Aneesa Ferreira and Ashley MitchellAshley Kelsey and Dario MedranoBig T and Corey LayBeth Stolarczyk and Jonna MannionDa'Vonne Rogers and Shane LandrumDevin Walker and Leroy GarrettFrank Sweeney and Sam McGinnKatie Cooley and Veronica PortilloKellyAnne Judd and Sylvia ElsrodeMelissa Reeves and Nicole ZanattaNany Gonzales and Turabi Camkiran (Turbo)This spin-off airs on MTV instead of Paramount+, unlike the previous four seasons.The Challenge All Stars: Rivals airs on MTV, on January 29, 2025.
