There are many similarities between The Challenge and Big Brother. Both shows require a careful balance between successfully winning physical or mental competitions and earning the favor and goodwill of other competitors through social strategy. Although The Challenge leans more toward the physical game, while Big Brother prioritizes the social game, competitors who succeed on both shows are typically skilled in both. Several former Big Brother players have now competed on The Challenge, including winners Josh Martinez and Kaycee Clark, but no competitors from The Challenge have yet to appear on Big Brother, despite the success that a select few would likely achieve.

5 The Challenge's Kyle Christie

Kyle Christie is notorious for his cunning social game and ability to play the middle ground. Originally from Geordie Shore, Kyle entered The Challenge: Vendettas and immediately formed several friendships (and romances) within the house. Not only is Kyle consistently able to fly under the radar and make friends with nearly every other competitor, but his physical strength has landed him in three finals and earned him over $70,000 in prize money. If Kyle played Big Brother, he would definitely be the life of the party, while also winning physical competitions.

4 The Challenge's Tula "Big T" Fazakerley

Tula "Big T" Fazakerley is consistently beloved by everyone in The Challenge house, which would make her a perfect fit for a game like Big Brother. Although her smaller size has prohibited her from winning The Challenge, she could easily get by on Big Brother using her social game. Since Big T retired from The Challenge to pursue her career in the culinary world, her return to reality TV would be much anticipated, and the show would require less of a time investment considering most Big Brother players only appear for one season. Her bubbly personality would likely steal the hearts of other players.

3 The Challenge's Ashley Mitchell

Ashley Mitchell is a two-time winner of The Challenge who is either loved or hated by her fellow competitors. Despite Ashley's strong and often controversial personality, she consistently s strong alliances to make it to the end, leading to Johnny Bananas referring to her as a "chameleon" who can fit in among different groups. When Ashley stole prize money from Hunter Barfield in The Challenge: Final Reckoning, she proved how cutthroat she can be to win, which is an attribute that would come in handy on Big Brother.

2 The Challenge's Devin Walker

Despite Devin Walker consistently proclaiming that he hates players who originate from Big Brother, he would actually thrive on the show if he was willing to give it a chance. Devin's greatest asset is his ability to stir the pot and divert attention away from himself. On Big Brother, seamlessly creating drama helps immensely come nomination day. Devin is also great at mental competitions, specifically puzzles, and he's never been one to shy away from making bold moves. Not only would he succeed at Big Brother, he would probably become a fan-favorite.

1 The Challenge's Kam Williams

Kam Williams has proven to be a strategic mastermind on more than one occasion, and her showmance with Leroy Garrett feels more like a Big Brother love story than one from The Challenge. On The Challenge: Final Reckoning, Kam pulled off a plan that kept her closest allies out of elimination by pretending to throw them in herself so no one else would think to vote for them. The plot, which involved some convincing fake arguments and tears, worked flawlessly. If Kam were to play Big Brother, her brain would get her all the way to the end.
