Reymond D. Gai is the main antagonist of SuperMarioGlitchy4's video Guards N' Retards: Le Train Breach. He's the former CEO of Reymond's Spaghetti and the proclaimed arch-rival of Tubby Wonka. He's also the Spy's boss. He's originally French, hence his French accent when he speaks English.
D. Gai is first seen in Guards N' Retards: Le Train Breach as Chris and SwagMaster enter his lair. SwagMaster is surprised by his midget size and begins making fun of him about it by threatening him that he'll "put a croissant up his ass". He punches Swagmaster in the stomach to stop him from teasing him because of his size. Then he opens the briefcase and takes out Tubby Wonka's secret spaghetti formula. He proceeds to tell the two friends his bankrupt backstory.
He explains to Chris and Swagmaster that the reason why he stole the formula was for one purpose: revenge. Tubby Wonka's company franchise, Fresh Spaghetti Tubby, was notable for a secret ingredient that Tubby Wonka's spaghetti had in it: Tubby Custard. The secret ingredient was the main reason why D. Gai went broke and he had to live a life of solitude. Before he could conclude his backstory, Chris and Swagmaster are asleep. He wakes them up by angrily shouting, "YOU SON OF A BITCH!!" He tells the Spy to take them out, so he won't have to deal with them stopping him from stealing Tubby Wonka's intelligence.
When Swagmaster corners him and begins distracting him, Chris arrives with Tubby Wonka and Sergeant Mark to stop D. Gai from getting away with the formula. The crew demands him to surrender, but D. Gai summons a giant flying spaghetti monster with a weird call and it fliess out of the window with him aboard. Chris tells Swagmaster to use the Titty Launcher. Swagmaster launches Morgan Freeman up to D. Gai and the monster (on which he sings the French Canadian child song Alouette) as he explodes the formula out of D. Gai's grip after saying "Everybody wants to smell like... titty sprinkles". D. Gai is seen at the end of the video with Mario as he crashes through the castle wall and says, "You did not see anything..."
