Pinkie Pie was wacky, goofy, and always a ball of sunshine and positivity. She was hyperactive and excitable, if a bit eccentric. Despite her extreme extroversion, she was afraid of her friends abandoning her or replacing her.
Pinkie Pie had a light pink coat, cyan eyes, and a bubbly, curly, hot pink mane and tail. Her cutie mark was two cyan balloons with yellow string and one yellow balloon with a cyan string.
Earlier G5 ideas featured redesigns of the Generation 4 characters from the cartoon. Pinkie Pie's wings are perhaps inspired by G4 concept art, where she was originally a pegasus. In the G5 concept art, her pegasus wings are usually very fluffy or floppy, a stark contrast from Rainbow Dash's sharp wings. Her hair seems to get even poofier, and she keeps her pink all over color scheme.
