Fancy Pants

Fancypants is a Canterlot high society unicorn pony who is introduced in the episode Sweet and Elite. Rarity describes him as the most important pony in Canterlot. His entourage party frequently change their opinions to agree with his own.

Development and design
Fancypants shares the same body design as the unicorns from The Gala Song, with a white coat, protruding bust, and an exceptionally large horn. His name comes from an informal term that means overly elaborate, swanky or pretentious.

Depiction in the series
Fancypants first appears in Sweet and Elite, when Rarity bumps into him and a white-coat pink-mane mare unicorn while walking through the streets of Canterlot. She instantly recognizes him as "the most important pony in Canterlot" and apologizes for running into him. He takes an interest in her when she mentions she is staying at Canterlot Castle by an invitation from Princess Celestia and invites her to his private box at the upcoming Wonderbolts Derby. He becomes more interested in Rarity after she correctly predicts the winner of the derby, and insists that she must be extremely important after she lies about knowing the trainer of The Wonderbolts, Rainbow Dash.

He features in Rarity's song montage, as well as in many of the social events. He also appears in a flying yacht, wearing a captain's uniform.

Later on, Fancypants greets Rarity at a garden party next to the room where Twilight Sparkle's birthday party is taking place. Rarity's friends crash the event when Twilight "realizes" that Rarity wants to attend it, and subsequently offend many of the upper class ponies with their raucous partying. While Twilight is dancing to music, Fancypants stops her to ask about the dress she is wearing, which Rarity had made but never finished. Twilight proclaims Rarity as the designer, and Fancypants is again favourably impressed with her, and gives it as his opinion that "every mare in Canterlot will be wanting one". This shows the influence he has when other ponies begin comment on how they would like a similar dress.

Personality
Despite being a pony of high social status and breeding, he contrasts with other Canterlot ponies such as Jet Set and Upper Crust in that he doesn't automatically dismiss ponies just because they come from a small town like Ponyville, although he doesn't take much interest in Rarity until he learns she is staying at Princess Celestia's castle. He also seems to carry a wider palette for fashion than other Canterlot ponies, as he expresses an interest in Rarity's more complete designs as well as the simple, half-finished dress that Twilight was wearing for her party, even before he knew that Rarity had made it.
