Sons of Mars

"Sons of Mars" is the fifteenth episode in season four of Adventure Time.

Synopsis
Jake becomes a copy of the Magic Man after a run-in with him.

Plot
The episode starts with The Magic Man taunting a deer (possibly the Stag) and notices a star following him. He transforms the deer into a telescope to be able to see the star, revealed to be his older brother, 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, the 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 the Magic Man and takes him to Mars.

Finn is enraged at the 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 the Magic Man to change his mind and take Finn back to his house. Magic Man shows Finn around his Trash Palace in order to find the Teleporter to find Jake, though he tells Finn he will be unable to use it. They come across a Tiny Manticore that Magic Man trapped inside a bottle. They find a picture of the Magic Man's ex-girlfriend who mysteriously died. Magic Man then takes Finn downstairs to find the teleporter to Mars. Despite the Magic Man's claims of the teleporter's inoperability, Finn thinks of Jake and is then teleported to the Martian City and attempts to get into the dome where Jake (mistaken for Magic Man) is put on court for the Magic Man's crimes against Mars and in the Land of Ooo. 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) and is interrupted by Finn who attacks Grob Gob Glob Grod, which causes Abraham to drop his staff on top of Jake, killing him. Finn is shocked at what happened and criticizes Abraham for not listening to Jake, causing Abraham to feel guilty and confronts Death. He offers Death a rusty penny, but Death rejects it, so Abraham is forced to sacrifice his immortality to save Jake (how he became immortal is unknown). After Jake is resurrected, Finn and Jake teleport back to Earth and attack the Magic Man. Finn then notices the tiny manticore calling him a coward and breaks the bottle telling him he is free. The manticore then flies off saying he did not need his help to get out of the bottle, but after departing, he thanks Finn by freeing him from his bottle prison, but emphasizes that his "new prison is shame". His shouting causes Finn to ask what he was saying, to which Jake repeats the manticore's words to Finn.

Trivia

 * This is Abraham Lincoln's first time on the show to be seen talking since the "Animated Short," and he is also the King of Mars.
 * 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 4 is seen poking out of the smudge of dirt.
 * The Magic Man is shown to have been in relationship that ended somehow. The promo art shows that his partner died by a fall from a cliff.
 * Abraham's appearance and voice seems to have been changed since the "Animated Short".
 * The tablet seen on the title card shows seven images connected by several lines. The first image is a representation of the solar system with lines from Mars pointing to the image of Magic Man and from Ooo (Earth) pointing to the image of Finn using the martian transporter. Under Magic Man and Finn is obviously Jake meditating. To the right of Jake is Abraham Lincoln. To the left of Jake is Grob Gob Glob Grod. The one on the bottom seems to be hand, this may be inaccurate. This tablet most likely refers to the prophecy referred to by Grob Gob Glob Grod when Jake was revived.
 * Originally, Ghost Princess was set to appear in the episode, but was written out of the storyboard according to Jesse Moynihan.
 * In the corner of the title card there is a dome similar to the one in Beautopia title card,.

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.
 * 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.

Episode connections

 * This is the second time a dead world was mentioned. The First was the 50th Dead World, mentioned in Ghost Princess.
 * The Magic Man returns in this episode since his debut in "Freak City".
 * The character, Death, returns in this episode since his debut in "Death in Bloom".
 * The earth is revealed to have a piece missing again, but it is not spherical, and has more color.
 * The food traveling in space is an allusion to "Too Young" and the prologue of "The Other Tarts."
 * This is the first episode for any of the Adventure Time charcters to physically leave The Land of Ooo.
 * When Jake dies, Grob Gob Glob Grod says that Jake was prophesized to meet them. This could be a reference to "The New Frontier".

Errors

 * The picture of Margles and Magic Man has an unusual dot in the background when Finn was holding the picture, but when Magic Man is looking at the picture at the end of the episode the dot is gone.
 * When Finn and Jake are seen on the Martian transporter, ready to leave Mars, Abraham Lincoln can be seen in the Space Dome alive.
