Twilight, Applejack, Fluttershy, Rainbow Dash, Pinkie Pie or Rarity?

Twilight Sparkle

Voiced by: Tara Strong

Singing Voice: Rebecca Shoichet

Twilight Sparkle is a unicorn
pony with a lavender body and an indigo mane and tail with pink and
purple streaks running through them. She is the primary protagonist of
the series. Extremely gifted with magic, she is Princess Celestia's protégée,
and she once considered knowledge more important than friendship. When
in danger of Nightmare Moon's prophecy, Princess Celestia sent her to
Ponyville to learn the importance of friendship, which proved valuable
in her confrontation with Nightmare Moon. She decides to stay in
Ponyville and study friendship with her mentor's blessings. Twilight
studies extensively and takes an organized, analytical approach to
solving problems. She also sometimes appears to have an insecure side in
some of the episodes when it comes to fitting in.^[1]
Unlike other unicorn ponies, Twilight can perform a wide variety of
magic, including teleportation on occasions. Her spirit represents the
element of magic. She has an older brother named Shining Armor, the
captain of the Canterlot Royal Guard and a Sister-in-Law named Princess
Cadance, Celestia's Niece. In "Owl's Well That Ends Well", she gained a
pet horned owl named Owloysius.

During the initial recording by the voice cast in Vancouver, Tabitha St. Germain does the reading of Twilight's lines as the cast record each show, before Tara Strong dubs over the lines in Los Angeles at a later date during the final mixing.^{[citation needed]}

Applejack

Voiced by: Ashleigh Ball

Applejack is an earth pony with an orange body and blonde mane and tail. She speaks with a Southern American accent.
Applejack is very trustworthy and laid-back, but sometimes tends to act
stubborn. She wears a brown cowboy hat and is the only one of the six
main characters who keeps her mane and tail tied back, instead of
letting them fall loose. Applejack comes from a large family of ponies
with apple-related names, spread all over Equestria, who oversee apple
orchards and run a group of businesses to sell apples and products made
from them.^[1]
She works in her farm Sweet Apple Acres, where she lives with her
younger sister Apple Bloom, older brother Big Macintosh and grandmother
Granny Smith. Applejack has demonstrated her strength and dexterity on
many occasions, and she is also very skilled with a lasso. She
represents the element of honesty. She has a pet Border Collie named Winona. Her catchphrase is "What in tarnation?!"

Rainbow Dash

Voiced by: Ashleigh Ball

Rainbow Dash is a pegasus pony with a sky-blue body and a rainbow-striped mane and tail. She is very brave and bold,^[1]
but also brash and arrogant, as well as sometimes being insensitive.
She has great speed and works with the other pegasus ponies to move
clouds around the sky and adjust the weather. Her lifelong dream is to
join the Wonderbolts, Equestria's aerobatic flight team (similar to the Blue Angels of the United States Navy).
Rainbow Dash's signature move is the Sonic Rainboom, in which she flies
fast enough to break the sound barrier, creating a sonic boom and a rainbow-hued
shock wave at the same time. "The Cutie Mark Chronicles" reveals that
when she did this move for the first time, she earned her Cutie Mark and
set in motion a chain of events that allowed the other five main
characters to earn theirs as well. She represents the element of
loyalty. In "May the Best Pet Win", after an animal race to choose her
pet, she gained a pet tortoise named Tank, who is then equipped with a helicopter rotor to enable it to fly to keep up with her.

Pinkie Pie

Pinkie Pie

Voiced by: Andrea Libman

Singing Voice: Shannon Chan-Kent in most songs, Andrea Libman in occasion^{[citation needed]}

Pinkie Pie is an earth pony with a pink body and magenta mane
and tail. She is a baker/confectioner at the Sugarcube Corner and a
party planner, but is very friendly, hyper, air-headed, and quite random
at times. She also enjoys singing and playing pranks, sometimes with
Rainbow Dash's help, but will not play any on Fluttershy due to her
sensitive nature. In "Swarm of the Century", she makes a musician out of
herself regardless of some other ponies' concerns about the
Parasprites. Her behavior is frequently random and chaotic at times and
she has been known to break the fourth wall. There is seldom a day without Pinkie's smile.^[1]
She possesses the "Pinkie Sense," an ability to predict events in the
immediate future through twitches of various body parts, as well as a
photographic or Eidetic memory.
When she becomes sad enough, her mane and tail go from curly to
completely straight and her pink coloration loses its brightness. While
she usually hops around, Pinkie is exceptionally quick when running,
able to keep pace with and chase down a hurrying, airborne Rainbow Dash.
She represents the element of laughter. She has a toothless pet alligator named Gummy.

In "The Cutie Mark Chronicles", Pinkie Pie tells the Cutie Mark
Crusaders that she was raised in a rock farm with a conservative family.
The visual flashback sequence accompanying her narration describes that
she had straight hairs until the wave of Rainbow Dash's Sonic Rainboom
brought her curly hairs and smile, and that at least her "mother" called
her by full name "Pinkamena Diane Pie". However, when she concluded her
story, she told them "[...] I can tell you the story of how I got my
Cutie Mark", making the story itself confusing.

Fluttershy

Voiced by: Andrea Libman

Fluttershy is a pegasus pony with a yellow body and a pink
mane and tail. She is sweet and calm, but often very shy and timid
around others. However, she can become forceful and assertive when
pushed too far or if her friends are placed in danger. Fluttershy has a
great love and care for animals and is willing to help them at any cost,
but is shown to be very fearful of dragons.^[1]
Although she is a pegasus, she prefers to stay close to the ground,
living in a cottage near the forest instead of the sky city of
Cloudsdale with the other pegasi. She possesses a special ability known
as "The Stare", which allows her to intimidate even the fiercest
animals. In 'Suited for Success', Fluttershy was shown to have good
knowledge of sewing and fashion just like Rarity. According to "The
Cutie Mark Chronicles", she has been saved by a group of colorful
butterflies allowing her to fly for the first time. Rainbow Dash's Sonic
Rainboom scares the animals, but Fluttershy befriended them and causes
her to earn her Cutie Mark, three blue butterflies with pink wings. She
represents the element of kindness. She has a pet rabbit named Angel.

Rarity

Voiced by: Tabitha St. Germain

Singing Voice: Kazumi Evans

Rarity is a unicorn
pony with a white body and a royal purple mane and tail which are
combed elegantly in wavy curls most of time. She is a fashion
designer/seamstress at her own dressmaking shop, the Carousel Boutique.
She is very stylish and beautiful, takes great interest in fashion and
clothing design, and often tries to make herself the center of
attention. She considers herself a lady and often acts sophisticated.
She can also be histrionic, making her quite dramatic.^[1]
She is Sweetie Belle's older sister and dreams of becoming a designer
for Princess Celestia. She also once hoped to marry Celestia's nephew
Prince Blueblood, until she actually met him, where he turned out to be
snobbish, rude, and self-centered. Rarity's magic has been demonstrated
to involve both telekinesis and finding nearby jewels buried
underground. She represents the element of generosity. She has a persian cat named Opalescence ("Opal" for short).
