Shoko

Shoko was the name of one of Finn's past lives. Many, many years ago she and her companion roamed the lands. She says she was mutilated and abandoned by her parents at a young age which resulted in her taking the path as a common criminal. She supposedly only has one arm because her parents sold her right arm for a laptop before dropping her at a dojo to give her fighting skills. Her parents never returned to the dojo, thus Shoko was left without parents.

She first appeared in "The Creeps" as a weird, amorphous ghost in a room in the Castle with Finn as he was hiding. Shoko again in her ghost form made a reappearance in "King Worm" when Finn unleashed his subconscious fears to escape his dream and then a picture of Shoko in her ghost form was seen in "Sky Witch," in Maja's house.

In "The Vault," Jake had BMO hypnotize Finn to recall memories he was suppressing in his mental vault and recalled the life of Shoko, his own past life. She was under the employ of the Bath Boy Gang and took on jobs for them, but her recollected job was to steal Princess Bubblegum's amulet. In order to get the amulet she spent some time befriending the princess, but then when she was given a new, mechanical arm, Shoko became conflicted. Fearing for her life, she decided to steal the amulet anyways but then, with the amulet in hand, she fell into a river of toxic waste and got horribly mutated into the amorphous blob form her ghost was seen in and then died on a hill. On that hill Finn's future tree house grew and her body happened to be laying in wait in the branches, holding the princess' amulet with deep regret for tricking her. Such deep regret to follow her in her future lives up until the present where that regret haunted Finn to that day when he called the princess to come over and he returned the amulet to her.

Personality
Shoko seemed to be very responsible for her age but due to her parent's neglect and her lack of being properly raised her views on what is right or wrong and her common sense were warped. Due to all this she took on the life of a thief and doesn't appear to see anything wrong with it. She begins to feel regret when she befriended Princess Bubblegum to steal her amulet for the Bath Boys Gang and enjoyed her time with the princess and was even welcomed into the Candy Kingdom. When it came time to actually steal the amulet she might not have if not for the meddling of the newly created Gumball Guardians forcing her to make a decision on the spot.

Appearance
In her former life, she was a humanoid who was notable for having one arm, the other being removed to be sold for a computer. Shortly before her death, she was mutated by being knocked into the radioactive sludge beneath the Candy Kingdom, turning her into a serpentine-like amorphous creature with two arms, the second grown back through her mutation.

Abilities
Shoko was a skilled fighter and thief and although she only had one arm, she was very capable. This is demonstrated, as she can still fight and carry buckets with little to no trouble. She also seems to work her new mechanical arm, even with the short amount of time she possessed it.

As a ghost
As a ghost, she was a weird, amorphous ghost in a room in the Castle with Finn as he was hiding. Shoko came out through the wall and gazed at Finn as her hair slowly filled the room. Finn broke through the wall to the next room to escape her, thinking that she had killed all of his friends and that she was after him too. He later found out though that the party was just a prank by Jake and that Jake had no clue who she was, that he must have imagined it. He then decided to forget the experience by putting it "in the vault."

Shoko again in her ghost form made a reappearance in "King Worm" when Finn unleashed his subconscious fears to escape his dream. This reveals that although Finn put the memory of her "in the vault," he is still subconsciously afraid of her or at least of his memories as her.

In "Sky Witch," Princess Bubblegum passes what seems to be a painting or picture of Shoko as a ghost in Maja's house.

This form has light grayish-blue ethereal skin with scale-like lumps and long, green seaweed-like hair. Her neck is unusually long. Her scales are light blue, her irises are black, and her pupils shine red. Interestingly, her appearance differs from the most of the other Ghosts in the series, who are all less colorful and more smoothly shaped. Her design is also similar to a Japanese style ghost. This form is a result of falling into the toxic river that once flowed through the Candy Kingdom, but had yet to be contained or neutralized. Upon being immersed, a newly formed Gumball Guardian attempted to rescue her, but the waste proved too noxious for their bodies within the seconds they attempted to fish her out.

Shoko phased through a wall, which was preceded by a ripple effect on the space and a humming sound. Her green hair grew to fill the library that Finn was hiding in, as if trying to reach him. She seems to be able to take possession of items, or produce hallucinations.

Trivia

 * "Sky Witch," what seems to be a framed picture or painting of the Shoko can be seen in a pile of stolen things while Princess Bubblegum explores Maja's storage room. Seconds later, in a different shot, Shoko's painting's expression suddenly changes, seemingly becoming more creepy or menacing. This was speculated to be due to the painting being sentient, possessed, or otherwise animate. However, artist Derek Hunter has confirmed that this was a mistake due to two different drawings being mixed up somewhere during production and that only one of them was meant to be shown in this scene.
 * The face in the second shot resembles Ogdoad's face.
 * Shoko is a traditional Japanese name implying that Shoko may be Japanese. This also shows that ethnicity was passed onto non-human life forms.
 * The robotic arm that Princess Bubblegum gifts to Shoko has similarities to Finn's robotic arm seen in "Finn the Human," "Jake the Dog," "King Worm," and "Puhoy."
 * This continues the trend of alternate versions of Finn, excepting the fictional Fionna, having artificial right arms.
 * Also like Finn, Shoko had an animal partner, except it's a normal white tiger, instead of a magical dog.
 * Shoko's appearance resembles that of her voice actress, Isabelle Fuhrman, and, like Fuhrman's previous roles, Shoko carries a knife or dagger as her weapon of choice much like Clove and Esther respectively.
 * Her voice actress, Isabelle Fuhrman, plays the role of Clove in "The Hunger Games."
