—Jack from Jupiter

Jack from Jupiter is a character in the Dynamite series The Boys. While not as violent or corrupt as some of the other Seven members, Jack does, however, willfully turn a blind eye to damage and crimes caused by The Seven.


Jack from Jupiter's skin was a tan color, mirroring that of the colour of the planet Jupiter. In a similar fashion he also had a red sphere affixed upon his chest to symbolise the Great Red Spot upon that same planet. In addition he wore a red cape.

He possessed no eyebrows or indeed any other visible body hair.


Jack was created by Vought-American along with the rest of The Seven. Despite his status as a long-time member of the world's most successful super team, his lack of the star appeal of some of his colleagues, as well as their violent excesses or major powers, means he is seen as fairly unimportant to his corporate sponsors (even more so than the Deep), and the Boys, a CIA-backed team charged with keeping superpowered individuals in-line. His teammates likewise see him as unimportant, as they are as self-absorbed as he is. Even the newer recruit A-Train, who Jack took under his wing to some extent, has little attachment to him, and showed little sympathy when Jack met with misfortune.

While investigating a murder, Hughie and Butcher make their way to Dr. Peculiar's office, and find records of Jack's sexual behavior. Eventually footage of Jack's deviant side is leaked to the news, and a panicking Jack grows more and more anxious as he wants Homelander to sort out who is blackmailing him. Basically ignoring Jack, all his teammates express little concern for his troubled state. The Seven do, however, confront The Boys on a rooftop in issue 59. Butcher denies sending out the information; Homelander analyzes Butcher and confirms he isn't lying. An enraged Jack panics further at the revelation when Homelander refuses to continue searching for an answer. Later, Butcher's dog Terror is found dead, and it is assumed by The Boys that Jack killed him. Butcher then tracks Jack to a backroom, shoves him against a wall, holds his throat closed and repeatedly stabs him in the stomach while questioning: "Why'd you kill me dog, Jack?"


Jack is like his peers: essentially a celebrity with superpowers, rather than a conventional superhero. To the shallow and obnoxious Jack, this arrangement couldn't be better as he has only ever sought a life of decadent hedonism. Although Jack is one of the more innocuous members of the Seven, he probably shouldn't be regarded as a decent individual, as he is aware of the violent crimes and fatal accidents they cause but shows no concern about them, even playing them down and treating these incidents like jokes.

Powers and Abilities[]

  • Flight: When his body is at minimum mass, Jack can fly through the air weightlessly. He can move at great speeds when this happens and has control over his speed force, being able to instantly stop moving while in the air by freezing his motion.
  • Superhuman Strength: Jack's base strength is considerably high due to his Carbon-enriched tissues. Jack can greatly increase his physical strength by increasing his density base strength to 50 tons and a maximum of 100 tons.
  • Invulnerability: By saying the word "Carpo", he is granted an exceptional level of superhuman invulnerability that comes in the form of a red toned force field.


  • Time Limit: He can't remain in his invulnerable form permanently so as to shoot up. Saying the word, i.e transitioning from non-invulnerable to invulnerable is painful.
  • Speaking: If he is somehow prevented from saying his word, he will stay vulnerable. This was confirmed when Billy chokes Jack, preventing him from saying his magic word to turn invulnerable, and repeatedly stabs Jack in the stomach with a knife until his intestines hang out and he dies.



  • In the comics, Jack from Jupiter is a one of the prime members of the Seven, however in the Amazon show his position is occupied by a different character, Translucent. Just like Jack, Translucent is able to turn his skin (virtually) indestructible, however the key differences being that Translucent can alter his skin at will, whereas Jack must say "Carpo" in order to change. Furthermore, Translucent's skin reflects light, making him virtually invisible, however unlike Translucent, Jack is capable of flight.
  • A male pornstar dressed as Jack appears in a pornographic movie during Butcher, Baker, Candlestick Maker, on his knees and surrounded by nude men, claiming that he wants "them all in at the same time". This mirrors the scene in the comic books in which a video of Jack having sex with a large group of transvestites is leaked onto the internet.
  • Jack is a mixed parody of the DC superheroes/Justice League members Martian Manhunter (for his abilities to shoot lasers and invulnerability, appearance and extraterrestrial appearance), Johnny Thunder (as his powers activate when he says a special word) and Hourman (due to his invulnerability only lasting for some time)
  • There is an easter egg reference to Jack From Jupiter in Stormfront's livestream during her first appearance in The Big Ride, A user in her chat can be spotted having the Username: JackoffFromJupiter.
