Fancy Pants

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

Development and design
Fancy Pants shares the same body design as the unicorns from The Gala Song, with a white coat, protruding bust, and an exceptionally large horn, about the size of Prince Blueblood's. Ironically, Fancy Pants doesn't wear any pants. His name comes from an informal term that means overly elaborate, swanky or pretentious. His voice actor, Trevor Devall, recalls being instructed to make Fancy Pants sound like John Cleese.

Depiction in the series
Fancy Pants first appears in Sweet and Elite, when Rarity bumps into him and Fleur Dis Lee 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, Fancy Pants 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, Fancy Pants stops her to ask about the dress she is wearing, which Rarity had made but never finished. Twilight proclaims Rarity as the designer, and Fancy Pants is again favorably 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.

Fancy Pants is seen with Rarity at the end of A Canterlot Wedding - Part 2. He also makes a cameo appearance in Too Many Pinkie Pies, with two Pinkie Pie clones appearing out of his hat.

Personality
Fancy Pants doesn't take much interest in Rarity until he learns she is staying at Princess Celestia's castle. He then invites her to the Wonderbolts derby and declares Rarity his new favorite party guest after she correctly predicts the winner and tells him she knows the Wonderbolts' trainer. He also expresses an interest in Rarity's simple, half-finished dress that Twilight was wearing for her party, even before he knew that Rarity had made it. He finds Rarity's friends "charmingly rustic" even though Jet Set and Upper Crust initially dismiss them.
