FINN
Finn (full title:
Finn the Human, known as
Finn Mertens in the
Farmworld timeline and formerly as
Pen in the
original short) is the main protagonist of the series
Adventure Time.
As shown in "
Memories of Boom Boom Mountain,"
Finn appears to have been abandoned in the woods during infancy. He
reveals that he made "boom boom" (Finn's word for defecation) on a large
leaf, fell on it, and lay there crying until
Joshua and
Margaret (
Jake's parents) rescued him from the wilderness to raise him alongside Jake, who becomes like a brother to him (as such,
Jermaine is also Finn's adoptive brother). In "
Memory of a Memory," a baby Finn is seen singing
a song in the bathroom of what appears to be Joshua and Margaret's house. In "
Henchman," when Finn is asked about his parents, he says Jake told him that he came from a cabbage, in jest. In "
Susan Strong," Finn states that he knows nothing of his human parents or any other humans.
FIONNA
Fionna is known to mostly keep her calm, she can be provoked to
anger. She will often try to act like one of the guys, so she fits in
easily with friends like Marshall Lee or Prince Gumball.
Fionna is a fearless, thrill-seeking, adventure-loving hero who
will rescue any prince from the Ice Queen or do any task to better
herself or help citizens. She, much like Finn, is also very hard-headed
as shown when Cake wanted her to date Prince Gumball and she was
stubborn about it.
So far, none of Fionna's fears have been introduced and she is known to be very courageous and brave.
JAKE
Jake (full title:
Jake the Dog), the deuteragonist of
Adventure Time, is a magical dog and
Finn's constant companion, best friend, and adoptive brother. Jake has
Stretchy Powers (which
he has had since he was a puppy), which allow him to stretch and
manipulate his body, coming in handy on innumerable occasions throughout
his and Finn's adventures. He is the son of
Joshua and
Margaret. Jake has a brother named
Jermaine.
Jake is 28 in magical dog years, though he rarely acts mature. Then
again, how exactly magical dog years correlate to human years remains to
be seen. Both he and his girlfriend,
Lady Rainicorn, share a passion for playing the viola. In the episode "
Jake the Dad," he and Lady Rainicorn have 5 puppies.
CAKE
She doesn't look much like Jake, aside from their body proportions. She
has white eyes in which the black pupils become circular if surprised,
excited, shocked, or scared. She has a cat muzzle and a small nose
(compared to Jake's), cat ears, white fur with many coffee colored
spots, and a large bushy tail. When Fionna and Cake race
Prince Gumball, when Cake runs up the mountain, she has claws on her front paws. In the
Fionna and Cake miniseries, Cake's eyes will go back to her original prototype blue color.
MARCELINE
Marceline, the Vampire Queen (full name:
Marceline Abadeer) is one of the main characters in
Adventure Time and a vampire that is over a millennium old. During
Finn and
Jake's
first encounters with her, she requests that they leave wherever they
are as the areas belong to her. Though initially an enemy to them, she
quickly becomes one of Finn and Jake's closest friends.
Marceline is over a thousand years old, as she said in "
Evicted!" and "
Daddy's Little Monster." In "
Memory of a Memory,"
one of Marceline's memories shows her as a young girl playing near the
burning ruins of a city, presumably the aftermath of the
Mushroom War. It is later found out in "
I Remember You" that the
Ice King gave her
Hambo during the war. It is revealed in "
Finn the Human"
that Marceline already knew the Ice King by the end of the war,
confirming that the events shown in "I Remember You" happened during the
war, not after. It has yet to be explained how Marceline returned to
her family. It is revealed in "Finn the Human" that Marceline was still
traveling with the Ice King as the events in that alternate universe
cause the Ice King to die and she chooses to guard his body.
MARSHALL LEE
Marshall Lee has a slim body, an average height, black hair, and light
gray skin. He has a matching permanent bite mark like Marceline's which
shows he is a vampire. In
Fionna and Cake and
Bad Little Boy,
he is seen wearing a red plaid shirt with gray stripes, dark blue
jeans, and brownish-red and white sneakers. Like Marceline, his physical
appearance is that of a typical late teenager or a young adult, but he
appears to be a little shorter than her. Also like Marceline, he looks
about the age of 18.
PRINCESS BUBBLEGUM
princess Bubblegum (full name
Princess Bonnibel Bubblegum,
[1] often called
PB and on occasion
Peebles, P-Bubs, or other nicknames) is a main character on the series
Adventure Time that first appeared in the
Animated Short. She is the benevolent ruler of the
Candy Kingdom, and is Finn's former love interest. She is also
Ice King's most often-targeted princess.
Marceline is the only person known to call her by her first name, Bonnibel, or Bonnie for short. At the end of "
Mortal Recoil," she was transformed into a 13-year-old, but returned to her normal biological age of 18 years at the end of "
Too Young." She has a gender-swapped character named
Prince Gumball created by the
Ice King in a fan-fiction.
PRINCE GUMBALL
Prince Gumball has the same color scheme as his female counterpart. He
has pink skin and his hair is somewhat in a coiffe. His head is adorned
with a small golden
crown
and a blue jewel. He wears a hot pink shirt with light pink puffed
sleeves and magenta slits. He also has magenta under-sleeves
(accompanied by dark-pink sleeve cuffs) and a large matching collar with
a small blue jewel inside a gold crest on it. He has a belt with
another golden crest and a small blue jewel design on the buckle,
dark-pink trousers with purple seams running down the sides, and indigo
dress shoes. Unlike his female counterpart, he has visible pink
eyebrows. Also, when his eyes enlarge, they are shown as purple.
FLAME PRINCESS
Flame Princess is the princess of the
Fire Kingdom as well as
Finn's current love interest and girlfriend. When
Jake asks
Flambo if he knows any princesses Finn's age, he responds that he knows "just the skirt... and she's
way hot." Flame Princess is locked in a
lantern in the main chamber of the
Fire Palace when Jake first encounters her in her candle cage where the
Flame King put her.
Flame Princess has a volatile personality; she usually has a calm
demeanor, though with rather frequent tendencies to sudden and violent
mood swings. She is described as "passionate" by Finn, "evil" by the
Flame King, and "intense" by
Pendleton Ward.
[1]
The Flame King also remarks that she is difficult to control. She seems
to be very sensitive and quick to judge. She is also prone to
unprovoked fits of aggression, as shown when she throws fireballs at her
citizens just for whispering. Flame Princess is also impressionable in a
positive way. She is very happy when Finn calls her beautiful. She was
also interested when Jake was giving her gifts in the episode "
Incendium"
and excited when her dad let her date "Prince Finn," though this
excitement quickly turns to anger when "Prince Finn" rejects her.
FLAME PRINCE
He has fire-like hair
styled up and a big red jewel on his forehead. He also has yellow skin and pointed ears.
He wears an orange and red suit and matching boots, each with a red jewel on it.
When he is turned into a small fire creature by the Ice Queen, he
has the shape of a small fire ball, retaining the red jewel on his
forehead.
ICE KING
he
Ice King (formerly
Simon Petrikov) is the main antagonist (often unintentionally) of
Adventure Time. His typical misdeed is to kidnap a
princess and force her to marry him, which
Finn and
Jake foil every time. As his name suggests, Ice King is also his title, announcing himself as King of Ice. He is the ruler of the
Ice Kingdom. His magical abilities, including his flight and
ice powers, are contained in his
crown, and he is therefore powerless without it. His crown is also the cause of his loss of sanity, his unusual blue skin color, his
goblin-like nose, his white eyes, and his beard. Some time before the
Mushroom War, he discovered the
Enchiridion and bought the crown.
ICE QUEEN
The Ice Queen has light blue skin, long white hair, and long
lightning-shaped eyebrows. Her hair, while also long like the Ice King's
beard, is wavy with curls instead of shaggy. She wears a small golden
tiara with red gems and a neck band bejeweled with a single blue gem in
the center. She also wears a blue long sleeved ball gown, and light and
dark blue shoes.
LADY RAINICORN
Lady Rainicorn is a
rainicorn and one of
Princess Bubblegum's royal steeds, best friend, and companion. She is also
Jake's girlfriend, and sometimes follows
Finn and Jake on their adventures. She speaks only Korean, using English only when equipped with a
Universal Translator (however, she is shown to have spoken a bit of English in "
Lady & Peebles"). Princess Bubblegum and Jake are the only other beings in the
Land of Ooo,
besides Lady's parents, that are shown to understand Korean. In "Lady
& Peebles," Lady revealed that she is pregnant; this was confirmed
by Princess Bubblegum. In the episode "
Jake the Dad" she becomes a mother to 5 puppies.
LORD MONOCHROMICORN
Lord Monochromicorn is the fictional gender-swapped version of
Lady Rainicorn created by the
Ice King in his fanfiction story, as seen in "
Fionna and Cake." He is the loyal companion of
Prince Gumball and the boyfriend of
Cake.
He communicates by using his hoof like a telegraph to communicate with
Morse Code, rather than by speaking Korean, as Lady Rainicorn does. (He
stomps his hoof for a dot and scratches the floor like a line for a
dash.)
BMO
As a robot, BMO's gender alternates depending on who is speaking or what make-believe scenario BMO is playing out.BMO looks like a half-Macintosh half-Game Boy Color with Atari 2600 controllers. It also shares some traits with a Vectrex.
BMO is a medium-sized blue-green handheld gaming device, sometimes
appearing with one or two controllers attached to it. When it's not
being played it has an 8-bit face.
BMO's front includes an arrow pad, a floppy disk slot, multiple
different shape buttons, two controller sockets, and of course the face,
or screen. There is also a compartment with a red button hidden
underneath the yellow D-pad.
LUMPY SPACE PRINCESS
Lumpy Space Princess looks like a purple cloud and speaks in a somewhat deep voice, like most
Lumpy Space People.
She has sharp teeth as well as a yellow star on her forehead that glows
while she is floating. There appears to be short hair on her body,
which she claims to be more of her "lumps." When she punches herself
(saying she can be "smooth"), she looks like a ball with arms. She is
not seen wearing a crown, like most other princesses; however, the star
on her head probably represents royalty, given that the only other Lumpy
Space People with that characteristic are her parents. The star on her
head is actually a jewel that goes very deep into her, as shown in the
episode "
The Lich."
When using all the jewels collected to open the Enchiridion book, Lumpy
Space Princess' star jewel just bounced off and was the only jewel not
able to be used.
LUMPY SPACE PRINCE
The
Lumpy Space Prince is the gender-swapped version of
Lumpy Space Princess. He appeared in the season three episode "
Fionna and Cake." He was only shown drinking something from a light-blue cup. He then appeared in "
Bad Little Boy"
hosting a party. Because so little of him is seen, most of his
similarities with Lumpy Space Princess are currently unknown; but Lumpy
Space Prince sounds almost exactly like
Lumpy Space Princess, just with a lower tone.
THE LICH
The Lich (formerly known as
the Lich King) is a powerful necrotic creature and a major antagonist in
Adventure Time. His first appearance is in "
His Hero" during a flashback about the adventures of the great hero
Billy. He plays the main villain in "
Mortal Folly" and "
Mortal Recoil," where he nearly kills
Princess Bubblegum.
The episode "His Hero" showed that Billy cast him down, and "Mortal
Folly" shows that he was ultimately imprisoned in a large glob of amber
in the ancient tree that serves as the castle of the
Candy Kingdom. After being defeated again in "Mortal Recoil," The Lich continued to inhabit the body of the waving
Snail, which appears in every episode. In the episode "
The Lich," he killed Billy and wore his skin to trick
Finn into helping him to unlock the true secret of the Enchiridion. This was confirmed by
Prismo in "
Finn the Human." The Lich was last seen in the episode "Jake the Dog."
