Svengallop

Svengallop is a male Earth pony and the antagonist of the season five episode The Mane Attraction. He is Countess Coloratura's bossy and flamboyant manager who exploits her for personal gain.

Development and design
According to writer Amy Keating Rogers, his name and character are a play on Svengali from George du Maurier's 1895 novel Trilby. His name original name in development was "Pony Baloney", which was changed for being too obvious.

According to Amy Keating Rogers, the original draft depicted Countess Coloratura outright firing Svengallop, rather than Svengallop voluntarily abandoning her. Rogers also stated that he returns to Manehattan in the events following the episode, where his continued shady dealings end in failure.

Depiction in the series
Svengallop appears alongside Countess Coloratura and her entourage in The Mane Attraction when they arrive to Ponyville for the Helping Hooves Music Festival charity event. He assumes an overbearing role in Coloratura's career, disapproving of her interactions with "common" ponies. During his time in Ponyville, Svengallop makes numerous unreasonable demands to Pinkie Pie without Coloratura's knowledge, and he threatens to pull Coloratura out of the festival if Pinkie does not comply.

Applejack attempts to convince Coloratura of Svengallop's unscrupulous managing, but Coloratura is skeptical. Twilight Sparkle records Svengallop's backdoor dealings with Pinkie Pie, and Coloratura finally realizes the truth, outraged that her manager has been using her fame to manipulate others. When confronted by the furious singer, Svengallop tells her that the show will fall apart without him and leaves in a huff.
