MTV’s The Challenge features no shortage of spin-offs, but one of the newest may be the best yet. On Mar. 8, The Challenge: World Championship debuted on Paramount+, and the global tournament contains legends, MVPs, and everyone in between.

Consisting of fan favorites such as Johnny "Bananas" DeVenanzio and Theo Campbell, highly-trained contestants vie for the “Challenge World Champion” title and $500,000 prize.

And the new reality competition’s hosts are just as impressive as its competitors. Let’s meet the four co-hosts of The Challenge: World Championship now!

Throughout his time-honored cycling streak, T.J. won seven X Games medals, ranging from gold to silver to bronze. However, during the Dew Tour Championships in 2010, he suffered a devastating injury that marked the end of his BMX cycling career.
