"Sons of Mars" is the fifteenth episode in the fourth season of Adventure Time. It's the ninety-third episode overall.


When Grob Gob Glob Grod comes to arrest Magic Man for his crimes, he switches bodies with Jake to escape his trials.


The episode starts with Magic Man taunting the Stag and notices a star falling from the sky. He transforms the deer into a telescope to be able to see the star, revealed to be his older brothers and sister, Grob Gob Glob Grod. Grob Gob Glob Grod, intending to capture the Magic Man, activates a device that drains the Magic Man's magic juice in an attempt to slow him down. As Finn and Jake walk beside a train track, while carrying broken parts of a robot for an unknown reason, Magic Man slams into them, knocking them to the ground. As Grob Gob Glob Grod closes in, Magic Man turns Jake into a duplicate of himself, and disguises himself as Jake. Grob Gob Glob Grod confronts Jake (disguised as Magic Man) and takes him to Mars.

Finn is enraged at Magic Man for framing Jake and demands that he should help him save Jake. Magic Man refuses to help him, explaining that his powers will remain in a drained state until Jake is executed on Mars. Finn attacks him, causing Magic Man to change his mind and take Finn back to his house. Magic Man shows Finn around the trash of his house in order to find a way to reach Jake, though he tells Finn he will be unable to use it. Finn finds a picture of Magic Man with a woman and tosses it aside. Magic Man then takes Finn downstairs to find the Martian transporter. Despite Magic Man's claims of the transporter's inoperable status, Finn thinks of Jake and is then teleported to Mars, just outside of the Martian city. Finn attempts to get into the dome where Jake (mistaken for Magic Man) is being accused of Magic Man's crimes against Mars. The King of Mars (Abraham Lincoln) gives him two choices of death (one by total annihilation, and the other by being turned into space dust), but is interrupted by Finn who attacks Grob Gob Glob Grod. Finn's attack causes Grob Gob Glob Grod to drop his wand on top of Jake, killing him. Finn is shocked at what happened and criticizes Abe for not listening to Jake. Abe feels guilty, so he confronts Death and offers him a dirty penny for Jake's soul, but Death chuckles and rejects the penny. Abe is forced to sacrifice his immortality to save Jake. After Jake is resurrected, Finn asks if they should go get Magic Man. Grob Gob Glob Grod tells him not to do so, as he had lost a friend and cannot lose his brother. Finn and Jake teleport back to Earth and attack Magic Man. Finn then notices a Tiny Manticore in a bottle calling him a coward, so Finn breaks the bottle and sets the manticore free. The manticore flies off and scoffs Finn's help, but begins a wholehearted monologue once he is farther away:

"I am the true coward. Hiding from sincere expressions like a vampire in the nude who hides from the light. Thank you, brave hero. I was freed from bottle jail, but my new shame. MY NEW PRISON IS SHAME!!!"

His shouting causes Finn to ask, "What's he saying?" to which Jake replies, "He said his new prison is shame."


Major characters[]

Minor characters[]




  • This is the first appearance of Magic Man's brothers Grob Gob Glob Grod whose names are mentioned throughout the series.
  • This is Abraham Lincoln's first time on the show to be seen talking since the original animated short, and he is also the King of Mars.
  • In the promo for this episode, it said NEW EPISODES.
  • The penny Lincoln offers to Death had dirt on it, covering the G and O of the word "God" and the last two numbers of the year the penny was made, the corner of what looks to be a 1 is seen poking out of the smudge of dirt.
    • The Penny has a D on it just below the date indicating that it was minted in Denver, Colorado. It was minted sometime between 2000 and 2099 as the last two numbers are covered by dirt.
  • Death's rejection of the penny implies that Lincoln has made a deal with him before.
  • Magic Man is shown to have been in a relationship that ended somehow. The promo art shows that his partner died by a fall from a cliff.
    • According to Lincoln and Magic Man, her name was Margles.
    • When Abraham Lincoln is talking to Jake, who he thinks is magic man. He says "I remember when you were really cool, before that night you spent on Olympus Mons, with Margles." At the end of the episode, while Finn and Jake are flying back to Earth, Magic Man is seen looking at the picture of the woman and himself, saying "Oh, Margles..." This means that the woman, Magic Man was in a relationship with, was named Margles and her death caused him to become "uncool."
  • This is the first episode which features a character that physically leaves the Land of Ooo.
  • This is the only produced episode to have been written by Doug TenNapel. He had previously storyboarded the early episode "The Glorriors," which was scrapped early during the production of the first season.
  • Originally, Ghost Princess was set to appear in the episode, but was written out of the storyboard according to Jesse Moynihan.[citation needed]
  • The dome on Mars has Mars' astrological symbol ( ♂ ) written all over it. When Lincoln turns into a statue the symbols that were on it disappear.
  • The scene where Grob Gob Glob Grod enters the Land of Ooo's atmosphere is reminiscent of the first page of Forming, a comic made by Jesse Moynihan.
  • Finn blamed Jake's death on the King of Mars even though it was technically his fault, and the King of Mars agreed that he made a mistake.
  • Abraham Lincoln mentions Olympus Mons (Latin for Mount Olympus), which is the largest volcano in the solar system and is located on Mars.
  • In the title card, the rock in front of the Mars Exploration Rover appears to show a portal or the Solar System (top), Magic Man (in the upper left), the Martian Transporter and Finn (upper right), Jake (middle), Grob Gob Glob Grod (lower left), The King of Mars (lower right) and a hand (bottom).
    • If the top image on the rock is the Solar System it shows the Sun in the center as a dot surrounded by five rings (orbits) with a line connecting a dot on the 3rd ring (Earth) to Finn on the transport and a line connecting a dot on the 4th ring (Mars) to Magic Man.
      • To the left in the title card, it shows the dome that this episode is set in, though it seems there's something different inside of it.
  • While Finn is being transported to Mars, when he looks behind him, the viewer can see Earth with a big hole/crater on the right side. This could be because of the Mushroom War. The meteor hurtling towards Earth can be seen in the episode "I Remember You" when the Ice King is in the 'The Past Room'. There is a picture of this in a cardboard box towards the bottom left side of the room when the Ice King enters the room with the memorabilia he has, though he does not remember any of it.
  • It is revealed in this episode, that the magic man had been sent to earth 200 years prior for his crimes on mars.

Episode connections[]

  • Magic Man returns to cause more chaos in this episode for the first time since his debut in "Freak City."
  • The character Death returns in this episode for the first time since his debut in "Death in Bloom."
  • The Stag returns in this episode, in a brief scene, for the first time since his debut in "No One Can Hear You." Even though it seemed that Jake had killed it and they flushed it down the sewers, therefore it could just be another stag.
  • The food traveling in space is an allusion to "Too Young" and the prologue of "The Other Tarts," specifically to the Galaxy of Flavors.
  • When Jake dies, Grob Gob Glob Grod says that Jake was prophesied to meet them. This could be a reference to Jake's croak dream with the Banana Man in Space that was the plot of "The New Frontier."
  • When Abraham Lincoln offers for Jake to have his consciousness spread throughout the universe, Jake showed that he was happy with this option just as Jake told Finn he was fine with a similar style of death in "The New Frontier."
  • Magic Man sings a short song while in Jake's form, with the line "...And the little people get left behind." In "All the Little People," Magic Man left a set of tiny people with Finn.
  • Tiny Manticore makes a reappearance in "You Forgot Your Floaties," "Normal Man," and "Bespoken For."

Cultural references[]

  • The rover depicted in the title card resembles NASA's Mars Exploration Rover, as the engraved tablet is a reference to the Pioneer plaque.
  • When Abraham Lincoln sacrifices his immortality to Death as a price for Jake's life, a gunshot can be heard. This references the actual death of Lincoln by his assassin, John Wilkes Booth.
    • The original storyboard itself features Death transporting Lincoln back to Ford's Theater in order to take away that immortality.
  • Coin offering is similar to how the dead were transported through the Styx River in the underworld in Greek Mythology.
  • After Abraham Lincoln is gone, where he was sitting turned into a statue that resembles the Lincoln Memorial in Washington D.C., USA.
  • The colored animated perspective behind Lincoln's head is a reference to similar shots in 2001: A Space Odyssey.
  • The trial of Magic Man on Mars is similar to the trial of General Zod, Ursa, and Non by Jor-El at the start of the 1978 film, Superman (shown again at the beginning of the sequel, and the 2013 movie Man of Steel) including the opening of a dome into space for the prisoner to take their fate, much like the three prisoners' exile to the Phantom Zone.

Storyline analysis[]

  • The King of Mars explains that Magic Man first changed when he went to Olympus Mons with Margles. Later in the episode, Magic Man reveals that Margles is the woman he was standing with in the picture.
  • Grob Gob Glob Grod was shown to be able to travel from Mars to Earth quickly, so they could have gone there to get water during the period of time in which Magic Man turned all the water on Mars into hair.
    • It is implied that many of the Martians wear hats now because they have not recovered from baldness due to Magic Man's water prank.
  • The tablet seen on the title card shows seven images connected by lines. The first image is a representation of the Solar System with only the first five planets. There is a line drawn between Mars and an image of Magic Man and one between Earth and an image of Finn using the martian transporter. Under Magic Man and Finn is Jake meditating. To the right of Jake is the King of Mars. To the left of Jake is Grob Gob Glob Grod. The one on the bottom seems to be a hand, though this may be inaccurate.
  • After seeing Jake in his true (dog) form, Grob Gob Glob Grod says, "Look. It's the dog. The one you were prophesied to meet," implying that there is a prophecy involving The King of Mars and Jake.
    • This prophecy is likely the petroglyphs that we can see in the title card for the episode. The petroglyph contains symbols of Earth, Magic Man, the Martian Transporter, Jake, Grob Gob Glob Grod, Abraham Lincoln, and some other symbol which resembles a hand.


  • When Finn and Jake are seen on the Martian transporter, ready to leave Mars, Abraham Lincoln can be seen in the Space Dome alive.
  • Finn and Magic Man were on the dirt by the railway track before Grob Gob Glob Grod took Jake. As Grob Gob Glob Grod leave with Jake, Finn and Magic Man are on the grass, then they are back on the dirt by the railway track again. Also, the parts of the broken robot disappeared and reappeared.
  • The number of Magic Man's fingers change from four (long shot) to five (close up) when he is by the railroad tracks.
  • When Magic Man and Finn get to Magic Man's house it is seen that it only had two windows and the window of the blue car was not broken. When they get closer the house now has three windows and the window of the blue car is broken.
  • When Lincoln orders the dome to open itself, the symbols ( ♂ ) on the walls are inverted as Finn is seen falling down.
  • Before Finn grabs the picture on the wall of Magic Man's house, though the picture is dirty, it can be seen it is upside down, when Finn grabs it he did not flip it but now it is not upside down. Also, Magic Man was in the right and Margles in the left, when Finn shows it they change places.
  • When Finn and Jake leave on the Martian transporter, they did not hold the handles. Magic Man stated that in order to activate the transporter you must hold the handles and think of someone. That was for his teleporter.
  • Finn and Grob Gob Glob Grod were both able to make noises in space, however this is impossible. In addition, Finn was breathing in space when he was being transported to Mars. It is unknown if the beam caused from the transporter made this possible.
  • When this episode was shown on Teletoon's "Can't Miss Thursdays," the title card was not shown.
  • In Tiny Manticore's monologue, the screen contains a blurred edges effect in the European version that isn't present in the American version.
