The Furst Family of Astro City. Julius and Augustus, the family's patriarchs, are pushing 70 and still inventing new technologies (Augustus) and kicking crazy ass (Julius). Although, admittedly, Julius and Augustus are the only Fursts to actually be Fursts; Nick and Natalie are the kids of Gus' third wife and one of his greatest enemies, and thus Astra (daughter of Natalie and Rex Zaurus, son of one of his other greatest enemies) isn't related to them, either.
Apollo, Midnighter and Jenny Quantum of The Authority. What's the only thing in the Wildstorm universe more badass than Apollo and Midnighter? Their adopted daughter Jenny, the embodiment of the 21st century who took over as their boss at the age of eight. As a family, they are so awesome they're terrifying.
The family of the fifth incarnation of The Fox as partially seen in The Fox Hunt. There's the titular vigilante Paul Patton, his wife who was once known as the She-Fox, his superhero daughter Fly-Girl who's part of the local superteam, and his teenage son Shinji who decides to take after his father with his own vigilante identity, The Ghost Fox.
Mack "Clownface" Delgado and his daughter Panda from Body Bags. His partner and honorary brother Pops Sekula acts as the grandpa to Mack's badass and Panda's Little Miss BadassDaddy's Girl.
BOOM Comics's Darkwing Duck revival turned DW and co. into this. Darkwing was already a Badass Normal. Then, his daughter Gosalyn became the new user of the Gizmoduck suit, becoming "Gosmoduck" and Launchpad McQuack has been given control of Quackwerks and its army of (now-former) police robots by his former employer, Scrooge McDuck.
Speaking of Scrooge McDuck, the McDuck/Duck family is a badass dynasty with its own Ominous Latin Badass Creed: ''Fortuna Favet Fortibus"note Fortune favors the bold, which is probably is a Shout-Out to the Duke of Wellington's Regiment, but hey. And yes, this includes Donald Duck.
One of the main families from Fables. Snow White and Bigby Wolf, the former Big Bad Wolf, are now married. They have seven children — six shapeshifters and one invisible zephyr. Bigby's father is the North Wind, and Snow's sister, Rose Red, is a battle-ready wild child. This family could (and does) wreak some serious damage when they have to.
The Diggers family from Gold Digger is made of this trope. You've got the Adventurer Archaeologist Gina, her adopted werecheetah and bodyguard sister Brittany who can run at mach speeds, the third sister Brianna who's known for making her own power armor and being a crack shot with a gun besides, the parents, an archmage (Theo) and the greatest warrior and martial artist of a parallel fantasy world (Julia), then finally Stripe, Brittany's husband, who's the apprentice of their world's superman after being bonded to some alien artifacts... from his world, he being an alien prince. Oh, and then there's young Tiffany, it's just a matter of time before she grows her badass wings ^^
Judge Dredd: Judge Fargo and his bloodline are full of badasses. The man himself founded the Judge system and cleaned up crime in the Mega Cities. His clone "sons" Joseph Dredd and Rico Dredd became some of the best Judges in the force (before Rico went bad), and Joe's own clones Rico (II) and Dolman became another highly-capable Judge and a Space Marine, respectively. Rico's daughter Vienna is a normal citizen, but can handle herself in a gunfight. And Fargo's mutant relatives in the Cursed Earth get this status just for surviving the Death World they live in. Old Stoneface, Rico, Dolman, and Vienna even formed an informal family eventually.
The Metabarons. Each male member of the family tree is so badass it's almost ridiculous: it begins with Othon, who kills an army of 1500 armored guys equipped with laser rifles with a knife, and it ends with Nameless, who's got implanted with bombs that make nukes look like petards, and can destroy entire universes almost at will...
Honorata is Badass herself too. She's a trained assassin and possesses mental power that can bend space and time.
Not to be outpaced, the Italian Mickey Mouse Comic Universe stories show that Mickey is the latest generation of one such dynasty, with the earliest known one being the ancestor who had to join the Pilgrim Fathers because, in the process of recovering the money for the supplies that had been stolen from them, he had been framed as a bandit. The most formidable alongside Mickey is likely his grandfather, who started out by volunteering to join the defense of Alamo as a teen (and surviving because Travis, seeing his young age, assigned him to deliver a message to Houston's army) and spent most of his life wandering the US specifically to have adventures, before finally marrying in old age-after marking the Texas Trail for his girlfriend.
Monstress has the Halfwolf family. Maika is an UnfetteredAnti-Hero who never backs down from a fight (and usually wins). Her mother Moriko taught her everything she knows. Her aunt, the Sword of the East, is the greatest warrior in the Dawn Court. And her grandmother, the Queen of the Wolves, is one of the most powerful and influential of the Ancients.
Nemesis is undeniably badass, being a powerful Magic Knight, holder of one of the deadliest swords in the galaxy And fused with a member of the ABC Warriors, greatest robot warriors in history. His uncle Baal, while old and rather out of his mind, is said to be an even more powerful wizard than him. It's often said that female Warlocks are much more powerful and dangerous than males and Nemesis' wife Chira lives up to that title. Their son Toth is insanely powerful having inherited his mother's powers after her death and adopts Satanus, a gigantic tyrannosaur who once fought Judge Dredd himself, as his pet. Nemesis' second wife, Magna, also qualifies, being able to give Chira a run for her money and having magic powerful enough to make Nemesis stop caring about war with Termight. And her father was once a powerful wizard. Nemesis kills Magna the moment he finds out about her part in Chira's death, but it was after they got married.
Satanus' family is pretty badass itself, being made of tyrannosaurs and all — aside from him there is his mother, Old One Eye, who has fought time-traveling cowboys, and his son, Golgotha, fought the ABC Warriors, a team of deadly robots. And if thought of as a family, rather than a Badass Crew, the ABC Warriors themselves are this and have a connection to Nemesis' family.
The Phantom: The Phantom is a long line of Badasses. Killing one just means their heir will come after you later.
The Sandman (1989): The Endless are all siblings that are more powerful than gods and have been around almost since the beginning of everything. When a family consists of the anthropomorphic personifications of Destiny, Death, Dream, Destruction, Desire, Despair, and Delight/Delirium, it's a good idea to stay as far away as is (in)humanly possible.
Star Wars: Invasion: In the wake of the Vong's invasion, Called Galfridian becomes a resistance leader on a Vong-occupied planet, his wife Nina becomes the pilot and primary planner of the captured Vong ship, their daughter Kaye becomes the leader of the refugee group, and their son Finn begins training as a Jedi.
Teenage Mutant Ninja Turtles: The Turtles, depending on the universe. The Turtles themselves are never confirmed to be related, but they consider each other brothers and Splinter their father. The 2003 cartoon and 2007 movie especially make this clear. In the '80s cartoon, however, they tend to act more like a Badass Crew with an Old Master. Lampshaded in Turtles Forever, where the '87 turtles are startled to hear the '03 turtles refer to Splinter as "Father".
