Natasha Romanova was formerly a Soviet spy, and wife to the Red Guardian (Alexei Shostakov). After her husband supposedly died as a pilot (a cover), she became a spy notorious throughout Russia. Her reputation was such that she was sent to America to recover Anton Vanko, the original Crimson Dynamo (who had defected and allied himself with Ironman). She later teamed up with Hawkeye to battle Ironman, before defecting to America. A former member of the Avengers, joining with then-lover Hawkeye, Black Widow has established herself as a hero in her own right, and was named leader of the Champions.

Warren Worthington III is a founding member of the original X-Men (Cyclops, Marvel Girl, Angel, Iceman, and the Beast). As the Angel, Warren possesses the ability to fly with his organic wings. He has also undergone extensive hand-to-hand combat training. He is the sole heir to the enormous Worthington fortune, and has dedicated that fortune to fighting on the side of justice, as a member of the Champions.

Laynia Petrovna is a Russian heroine, who was originally part of a group (including her then-lover Yuri Petrovich/Crimson Dynamo and the Titanium Man) who were sent to Los Angeles to capture the Black Widow and return her to the USSR. There, they allied with Rampage and the Griffin, and battled the Champions. Laynia, however, realized that she was fighting on the wrong side, and defected to America, leaving the Crimson Dynamo and her former allies behind. She has joined the Champions and is currently involved with Bobby (Iceman) Drake. She controls the mysterious dark force energy.

Bobby Drake is also a founding member of the original X-Men. He has control over ice, being able to transform water into ice, as well as erecting solid ice forms with a silent mental command. Undergoing extensive training with the original X-Men, Bobby left the team (along with Warren) after the new X-Men were recruited. He has since joined the Champions as a founding member of that team.

Johnny Blaze grew up with a father who was a stunt daredevil. When his father died, he was raised by “Crash” Simpson, who had his own traveling cycle show. When “Crash” was dying of cancer, Johnny sold his soul to the Devil, in return for “Crash” being cured of cancer. His cancer was cured, but he died in a stunt. Only Roxanne’s love for Johnny was able to prevent the Devil from taking Johnny’s soul. But, in the process, Johnny was bonded with the demon Zarathos. Due to this relationship, Johnny transformed into a flaming skeletal form, calling himself Ghost Rider. Gradually able to control his transformations, Johnny has continued his career as Ghost Rider, and as a member of the Champions.

Bill Foster worked as a lab assistant for Hank Pym, becoming close friends with Yellowjacket. Over the years, he worked closely with Hank Pym, and learned a great deal about the Pym Particles (which transformed Hank into Giant-Man/Goliath). Returning home to the Los Angeles area (where he grew up), he transformed into Black Goliath initially to help Luke Cage overcome the Circus of Crime. A brilliant scientist in his own right, Black Goliath has also started his own career as a super-hero, having worked with the Champions on occasion, prior to joining the team.
