In My Little Pony series, there are six main characters as Apple Jack, Pinkie Pie, Rarity, Fluttershy, Rainbow Dash and Twilight Sparkle. Each character has a unique task and they try to finish their task. With the different personality, they represent multi-element. My Little Pony Twilight Sparkle represents the element of magic, Apple Jack represents the element of honesty, Fluttershy represents the element of kindness, Rarity the element of generosity, Pinkie Pie represents the element of laughter and Rainbow Dash represents the element of loyalty. They make My Little Pony more various and interesting.
As you know My Little Pony Twilight Sparkle is the central character of the series. She is depicted in the show's first three seasons of My Little Pony film. Her main coloring body is purple with a pink-streaked indigo mane. If you follow this film you can see Twilight Sparkle as a leader. She guides five main characters Apple Jack, Pinkie Pie, Rarity, Fluttershy, Rainbow Dash and Spike in their adventures and helps resolve her friends' differences.
She helps also Princess Celestia to rule Equestria Land. She is very smart and lives with Spike and pet owl named Owlowiscious in Ponyville's Golden Oak Library. Her friends call her as a bookworm because she likes much reading. She has an important task to become responsible for spreading friendship across Equestria from the Castle of Friendship. She is loved by her friends and everyone with her personality.
As the name, Rainbow Dash is the character that has a rainbow-colored mane and a blue pegasus. She has a goal to participate in her heroes, the elite Wonderbolts aerobatic team. You can follow it in the Newbie Dash episode. She helps also other pegasi manage the weather around Ponyville. She lives with her pet tortoise named Tank in a floating condominium of clouds called the Cloudominium. Because loyalty is her personality traits, so they can use her to teach the children and bring us positive traits.
Pinkie Pie has the main pink color. In My Little Pony film, she is as the planner at Sugarcube Corner. She is known as a comedic character. She is always cheerful, energetic, and talkative. Pinkie Pie is a source of much of the series' humor. In the course of the film, she is humor and makes often her friends smile and depending on the episode or scene, Pinkie's friends alternate between detesting and enjoying her company. This is a character that children like from appearance to personality.
