Introduced in Castle Wolfenstein
- Alternate History: His mission to kill Hitler is based on the July 20 plot, which failed in real life.
- Chuck Cunningham Syndrome: Last seen in 1984's Beyond Castle Wolfenstein, and has effectively been replaced by B.J. Blazkowicz in all of the post-Muse installments.
- Dressing as the Enemy: A contributing factor to his escape from Castle Wolfenstein and infiltration of Hitler's bunker.
- Everybody Calls Him "Barkeep"
- Featureless Protagonist: Due to the simple graphics, he is given no defined appearance apart from the A Winner Is You screen at the end of the game.

Introduced in Wolfenstein: The New Order
Anya Oliwa's grandparents.
- Badass Grandpa / Never Mess with Granny: They really don't like Nazis.
- Battle Couple: They each take turns blowing a Nazi away with a double-barrel shotgun.
- If You Ever Do Anything to Hurt Her...: Roman tells B.J. as such concerning Anya. B.J. just simply nods his head.
- Improbable Aiming Skills: Downplayed but still impressive for an elderly woman. While driving through a Nazi checkpoint, Olenka shoots a double barrel shotgun out the window of a moving car and nails a Nazi that had just opened a door a good distance away from the car.B.J.: She's got good aim for an old dame.
- Mr. Exposition: They bring B.J. up to speed on the horrifying fact that while he was in a coma, the Nazis pretty much took over the whole world.
Introduced in Wolfenstein II: The New Colossus
- Empty Nest: BJ running away to join the army broke her heart, if Rip's account of things can be trusted.
- Good Parents: She was kind, loving, and supporting of BJ growing up.
- House Wife: Not that she doesn't work hard, despite what her husband says.
- Jewish Mother: Subverted, as although she is Jewish, she acts nothing like the stereotype.
- Mama Bear: Has the attitude of one, but given that her husband is twice her size, she can't stop him, just stand up to him.
- Nice Girl: A kind soul, and a loving mother to BJ.
- Sacrificial Lion: Her own husband sells her out to the Nazis for money, and because she called him out on being a bad businessman. It's revealed she died in a concentration camp.
- Women Are Wiser: She is much more level-headed than her Hair-Trigger Temper husband, and she lets Rip have it for losing all the money her family invested in his so-called business, and that she works just as hard as he does despite his claims otherwise. In a sure sign of mental stability, She also doesn't abuse her spouse and son, unlike him.
- One Steve Limit: Subverted. This Billie is spelt with a feminine "IE" while our protagonist uses the masculine letter "Y".
- Puppy Love: Confesses to having a crush on B.J. It's left ambiguous if he returned it.
- Small Role, Big Impact: Her friendship with B.J. helped steer the latter's morality in the right direction, despite his father's strict stance on race and isolation.
- Uncertain Doom: B.J. wonders what's become of her now that the Nazis have taken over the world.
- Richard Nixon the Used Car Salesman: Due to Reagan never taking an interest in politics due to the Nazi invasion of the US, this timeline sees Ronald Reagan the TV-Actor.
- Mistaken for Spies: After he accidentally insults Hitler, the latter furiously holds him at gunpoint, accusing him of being a Jewish spy. Needless to say, it doesn't end well for him.
- Multiple Gunshot Death: Happens to him when when he draws Hitler's ire by inadvertently pressing one of his main Berserk Buttons, namely calling him "Mr. Hitler" instead of "Mein Fürher".
- Nice Guy: For his brief moment on-screen, Reagan comes across as a pleasant, eager to please guy.
- Older Than They Look: Reagan was only 20 years younger than Hitler and would have been around 50 in 1961.
- Too Dumb to Live: Was he really expecting the increasingly senile and Ax-Crazy leader of the Third Reich to respond well to "Mr. Hitler"? Bonus points as he and the other actors were forewarned to be really careful what they said or did around him.
- We Hardly Knew Ye: Doesn't even get a chance to act in the audition before getting shot to death.
Introduced in The Freedom Chronicles
- Voiced By: Tim Russ
A former professional quarterback enslaved and brutalised by the Reich, Joseph Stallion's public display of defiance against his fascist oppressors led to his internment at Research Station Omega in Springfield, Illinois - under Uberkommandant Roderick Metze, an American dentist turned Nazi collaborator. But Joe was not a man to be caged; he broke free and escaped the facility to pursue bloody revenge.
- Charles Atlas Superpower: No explanation for Joe's amazing ramming power and ability to regenerate armor is ever given other than that he was once a pro football player.
- Homage: Basically a walking one to the Blaxpliotation genre.
- I Know Madden Kombat: Joe retains the Ram Shackles' special ability to bash through concrete walls and steel gratings. This is explained as a leftover of Joe's football skills. If he runs at you, don't stay in his way.
- It's Personal: Metze enslaved Joe's father, and indirectly caused his death. Joe's mission to avenge his Papa takes him to Venus itself.
- Mundane Made Awesome: Joe can throw empty cans to distract guards. This replaces his thrown weapon, but he doesn't need one: he kills Nazis with his bare hands!
- Soccer-Hating Americans: Inverted; the Nazis dismantled American football, so Joe successfully made the jump to association football.
- Super Strength: Arguably even stronger than Blazko himself. He doesn't need a super soldier's body and a special gadget to smash through sheer concrete!
- Voiced By: Claudia Black
This British former agent of the Office of Strategic Services has spent years fighting the Nazis from the shadows. Her latest venture takes her across the world and beyond in search of the men responsible for the death of her husband Jack. Will she be able to find and assassinate her latest target?
- Action Girl: She was the only female playable character in the series until the announcement of Wolfenstein: Youngblood.
- Battle Couple: She and her husband were decorated OSA spies.
- Contralto of Danger: She's voiced by Claudia Black, so her voice is naturally deep.
- Dark Is Not Evil: Jessica wears black and has the appearance of a James Bond movie villainness, but she is fighting against the Nazi regime from the shadows.
- Drowning My Sorrows: She spent the years after her husband's death getting drunk in Brazil and is constantly talking about her alcoholism. If she gets caught by other enemies, she'll note that the drinking might have taken it's toll on her.
- Eyepatch of Power: She sports an eyepatch over her left eye and is plenty deadly.
- Femme Fatale: Certainly has the aesthetic down pat.
- Fragile Speedster: Jessica's maximum armour is limited to 40; as a Stealth Expert, she dislikes burdening herself too much. However this does mean she is considerably more vulnerable in protracted firefights.
- Knife Nut: The New Order's old knives make their return as Jessica's melee weapon of choice.
- Roaring Rampage of Revenge: Her DLC is all about her getting vengeance on the men who killed her husband.
- Stealth Expert: Jessica retains the Constrictor Harness' ability to fit through incredibly tight spaces. This is justified by her past infiltration training. The fact she's much smaller-framed than B.J. probably helps too.
A former US Army Captain renowned for his deeds during the war, Gerard Wilkins had been reduced to hiding from the Nazis in the ruins of Manhattan, on a mission to destroy the Nazis' latest superweapon: the Sun Gun. His quest takes him to the Nazi bunkers of Kodiak Island, Alaska. Can he infiltrate the bunkers and destroy the prototype weapon before it can be used against innocent Americans?
- An Axe to Grind: Like B.J., he uses hatchets for melee and throwing.
- Badass Baritone: His voice is much deeper than even B.J.'s.
- Old Soldier: He's the oldest of the playable characters.
- Still Wearing the Old Colors: Still wears his old Captain's uniform even after the fall of the U.S. military.
- Stone Wall: Wilkins' overcharged health doesn't deplete unless he's taken damage, so technically his max health is 200, much higher than other player characters.
- Tricked-Out Shoes: Wilkins wears a pair of captured Kampfwanderer telescoping boots, which basically give him the same extendable stilt-walking ability as B.J.'s battle walker upgrade from the main game.
