Jupiter’s Legacy is this 2021 superhero show based on comic by Mark Millar and Frank Quitely. It follows first-gen superheroes who saved humanity for almost a century. But their kids? Yeah, they can’t seem to catch a break. They deal with high expectations and a world that’s gone totally bonkers. The cast includes Josh Duhamel, Ben Daniels, Leslie Bibb and a few others you might recognize.

Meet the characters from Jupiter’s Legacy

Sheldon Sampson/The Utopian

Okay, Sheldon is the classic stoic golden-age hero but like, with way more lectures about responsibilities — he’s the dad you both respect and quietly fear. He believes in rules, order, and the big ideal of saving society, and yet he’s awkwardly romantic in private ways (he owns a ridiculous tie collection and also swears he once tried to crochet; don’t fact-check him). He’s severe at family meetings but will also pause mid-speech to make a terrible pancake joke, which is somehow the worst and best. Deep down he’s terrified of failing the legacy he inherited, which makes him inspiring and exhausting in equal measure.

Walter Sampson/Brain-Wave

Walter is simmering resentment wrapped in genius — brilliant, bitter, and absolutely convinced the world is fundamentally unfair to him. He invents crazy machines and has the kind of smug smile that means he’s two steps ahead and also planning revenge, probably while drinking something bitter and slightly overcomplicated. He flips between charmingly charismatic and disturbingly cold, and yes he loves classical music one minute and smashes a radio the next, because mood swings, obviously. There’s hurt under the anger, you can see it in the tiny rituals he keeps (he organizes his pencils by guilt level? I mean, that could be a metaphor or literal).

Grace Sampson/Lady Liberty

Grace is the mother-of-heroes you want and the moral compass you can’t help arguing with — regal, endlessly patient, and secretly ferocious. She runs on duty and love, but will also binge cheesy rom-coms in secret and cry at the stupidest scenes, which humanizes her in a delightful way. She tries to keep the family together like it’s a sacred mission, but she’s also got these tiny rebellions — midnight drives, snapping at bad coffee — that make her feel real. People project perfection onto her and she almost wears it like armor, until the armor cracks and you see the fierce person underneath.

Chloe Sampson

Chloe is the bratty, edgy middle child with a camera phone and attitude for days — she’s flashy, sharp-tongued, and incredibly lonely if you look too long. She’s always provoking grown-ups (and younger siblings) for fun, but she can also be unexpectedly tender, like she collects weird rocks for reasons she won’t explain. She posts everything but actually cherishes privacy — weird contradiction, I know — and has a soft spot for street art and smoky jazz bars. Honest? She’s chaotic in a very curated way and you can’t decide whether to be annoyed or impressed.

Brandon Sampson

Brandon is all storm and short fuses — brooding, dangerous, a classic “I don’t need anyone” type until he absolutely does, then everything collapses. He’s impulsive to the point of self-sabotage and has this tragic-prince vibe, like he grew up reading too many revenge novels and not enough coping manuals. But he also rescues stray dogs and cries to old vinyl records, so he’s not totally hopeless; just very melodramatic. Sometimes he’s a walking cliché and other times he surprises you with a tiny, painfully sincere kindness, which is when you really fall for him (or want to throttle him, same thing).

Fitz Small

Fitz is the nerd heart of the team — brilliant gadgeteer, awkward smile, and an anxiety spiral in human form, but with the sweetest intentions. He builds insane tech on a shoestring budget and a prayer, and his workshop is full of wires, coffee rings, and weird little action figures that definitely, absolutely have names. He stumbles socially but when he talks about physics you’ll actually want to listen, and there’s a quiet bravery in his loyalty that sneaks up on you. Also he hoards bookmark tabs like trophies, which is both adorable and mildly concerning.

George Hutchene

George is the slippery politician type — polished, manipulative, and the person you’ll love to hate at a cocktail party. He smiles like he’s your friend but is calculating deals in the back of his head; that charisma is almost a weapon. He wears the perfect suit and has that smell of old money and bad decisions, yet he can also be annoyingly sincere when it suits him, which keeps people guessing. Honestly, he’s the kind of guy who’d bring you a cake to a meeting and then quietly take your vote, so watch the cake.

Petra Small

Petra is scrappy, fierce, and full of surprising tenderness — she’s seen hard things and learned to answer with fire and quick wit. She’s loyal to a fault, the sort of friend who will steal you a sandwich and then help you plan an escape route, and she talks with a blunt honesty that is both refreshing and terrifying. Underneath that tough exterior she’s small soft moments — humming to herself when she fixes a toy, keeping stupid mementos — so don’t assume she’s all edge. She’s complicated in the best way: equal parts survivor, troublemaker, and someone who will absolutely prank you at midnight.

Sierra Ectoplex

Sierra is neon energy and high-tech chaos — part influencer, part hacker, totally unbothered and delightfully dangerous. She loves spectacle, dripping in LEDs one minute and deep in code the next, which makes her unpredictable and very fun to watch. There’s a theatrical streak to everything she does (entrance music? of course) but she’s also smart in a way that’s quietly ruthless, like she plans three moves ahead and snacks while doing it. She collects vintage cameras for no practical reason and insists they’re “for art” even though half of them are probably broken.
