Gustave le Grand

Gustave le Grand is a griffon and a baker that appears in the episode MMMystery on the Friendship Express. He is the second griffon to appear in the series, after Gilda.

Depiction in the series
Gustave first appears boarding the train to Canterlot, gloating about how his éclairs would win first place at the National Dessert Competition instead of the Cakes' cake.

Pinkie Pie theorizes that he is the culprit behind the damaging of the Cakes' cake, until Twilight Sparkle proves that Gustave didn't do it after the other bakers' entries are eaten. When Pinkie Pie accuses him of eating the cake, an imaginary scene occurs in which Gustave ties Pinkie to a train track with a train hurtling towards her and sets the MMMM on a conveyor belt moving towards a saw, portraying him as a classic dastardly villain from black and white silent films.

Pinkie, having learned to get the facts straight and not accuse without proof, reveals that the culprits who ruined the other entries were the bakers themselves. Gustave ate Mulia Mild's Chocolate Mousse Moose, Donut Joe ate Gustave's éclairs, and Mulia ate Joe's Donutopia. At Pinkie's suggestion, the remainder of Gustave's éclairs are combined with the other leftover treats to form a new cake that wins first prize.

Personality
Gustave is an arrogant baker, believing without a doubt his éclairs will win first prize. When it is discovered that he ate Mulia's Mousse Moose, he admits it was not out of spite but rather because of how Pinkie Pie described it, and sincerely compliments Mulia. He speaks with a somewhat stereotypical French accent, substituting some "th" sounds with "z" sounds and infrequently using French phrases.

Quotes
"Zis is not so, for I, Gustave le Grand, do challenge your crude cake to a duel of delectable delicacies, against my exceptionally exquisite éclairs! They will undoubtedly strike down all the competition, winning first prize and crowning me the champion."
