Countdown to Final Crisis
Prepublication solicitations for various Countdown to Final Crisis tie-ins referred to the group of Donna Troy, Jason Todd, Kyle Rayner, and "Bob" (a nefarious, renegade "purist" Monitor), as "Challengers from Beyond". This group went on a quest through the newly formed multiverse to find Ray Palmer, whom Bob claimed was essential to the survival of the universe. Eventually the Earth heroes were betrayed by Bob, who sought to kill Palmer, rather than protect him or acquire his aid. Palmer, Troy, Todd, and Rayner found themselves involved in a war between the Monitors and Monarch's forces. Later they traveled to Apokolips, where they teamed up with Jimmy Olsen, Forager, Karate Kid and Triplicate Girl. After returning to Earth, Troy, Rayner, Forager, and Palmer decided to team up again. They traveled to the Monitors' headquarters, where they informed the shocked beings that they would be watching over them as a sort of interdimensional border guards.
The Brave and the Bold
The 2007 revival of The Brave and the Bold series features a storyline involving the Challengers. Destiny of the Endless reveals to Supergirl and Lobo that his Book of Destiny has changed because there appeared to be men who existed, but were not recorded in the book, and their undocumented actions made the book unreliable. Destiny cast the book away, and it was eventually recovered by Batman and Green Lantern with the help of the Challengers, the men in question, who become the new holders of the book. Destiny later reclaims the book.
Leslie "Rocky" Davis appears regularly in Doom Patrol, in which he serves as something of a counselor to the members of that team, and resides on Oolong Island.
Post-Flashpoint
In 2011, the DC Universe was dramatically altered, giving very different back stories to many of its heroes and villains. This version of the Challengers incorporates elements of the original and 1990s lineups.
The Challengers were formed for a reality television contest, when several notable people were assembled by archaeologist presenter Clay Brody for his "Challengers" program. Clay, the contestants, producer June, and pilots Ace and Maverick, were lost in the Himalayas when their plane crashed under mysterious circumstances.[14] All but one of them showed up weeks later, remembering a recuperation in Nanda Parbat, in which the city's elder told them to beware the unknown, but also to challenge it. Returning to civilization, the group found a talisman that had led Clay to pick them, and a note explaining that it was one of a set.
The Challengers program was retooled to take advantage of the quest. With their home base on a Metropolis soundstage dubbed Challengers Mountain, the group sought out the talismans in far-flung corners of the world, usually accompanied by some oddity, like warrior statues or giant-ant-spewing portals. Their greatest initial challenge came when in a short period their show was cancelled and they were attacked by their dead friend, "Ace" the pilot. Though he killed two of them, they managed to defeat him, and the survivors vowed to find the rest of the talismans and save the world.
Rebirth
The original Challengers Prof, Ace, Red, and Rocky were on a mission on an Earth in the Dark Multiverse when Prof was badly wounded. He figured out how to use the dark energy to heal himself. In doing so he inadvertently sent his dark multiverse counterpart to the multiverse. The Dark Prof created a new Challengers that he could use to collect the remains of an ancient god whose remains were flung through time and space when the Source Wall was destroyed. The Dark Prof recruits Trina Alvarez, Moses Barber, Krunch, and Bethany Hopkins as the most current incarnation of the team. They soon discover his evil intentions and send him back to the Dark Multiverse, saving Ace, Red, Rocky and Prof in the process.[15]
Alternative versions
DC published two other series, also titled Challengers of the Unknown, featuring the original Challengers' concept combined with a new set of characters.
The Challengers were revamped by writer Steven Grant in vol. 3 (1997); this iteration had a totally new group of characters and was one of four series making up the Weirdoverse group of titles. This ongoing series ran 18 issues, through 1998. This team of paranormal investigators met the original Challengers and even had Rocky agree to advise them.
One more revamp was done by Howard Chaykin in a six-issue miniseries (vol. 4, 2004–2005). This series had another new group of characters and was entirely unrelated to the previous two incarnations.
