Fourth My Little Pony incarnation (2010–2021) My Little Pony: Friendship Is Magic Rarity is introduced in the series premiere as a sophisticated unicorn with a talent for finding gems and creating fashionable attire. Her backstory is explored in "
The Cutie Mark Chronicles", which reveals she was struggling to make costumes for a school play, and her horn unexpectedly pulled her toward a large rock. Shortly afterward, she witnessed
Rainbow Dash's Sonic Rainboom, which caused the rock to shatter, revealing it to be full of gems. She discovered her talent to find gems to improve her designs, earning her
cutie mark of three diamonds. Throughout the series, Rarity works to establish herself as a renowned fashion designer. In "
Suited for Success", she designs dresses for her friends for the Grand Galloping Gala despite her friends' increasingly impossible demands. The episode "
Rarity Takes Manehattan" explores her competitive side as she enters a prestigious fashion competition in Manehattan, learning important lessons about maintaining integrity in the fashion industry. Rarity's relationship with her younger sister Sweetie Belle is developed in episodes like "
Sisterhooves Social" and "
For Whom the Sweetie Belle Toils", where they navigate typical sibling conflicts while strengthening their bond. In the episode "
Sweet and Elite", Rarity is torn between attending an elite Canterlot garden party and celebrating Twilight's birthday with her friends. As the series progresses, Rarity opens a second boutique in Canterlot called "Canterlot Carousel" in the fifth season, and a third boutique in Manehattan called "Rarity For You" in the sixth season. She also achieves her dream of designing for Canterlot's elite and royalty on several occasions.

Equestria, she uses her charm and generosity to help win over potential allies, particularly during their encounter with Capper, a con artist cat whom she befriends by fixing his damaged coat. Rarity's generosity is highlighted when she willingly gives away her collection of gems to persuade Queen Novo to help them save Equestria. During the final confrontation with the Storm King, she uses her unicorn magic to help defeat the villain and restore harmony to Equestria.
