Bluffing the Imposter in Video Games.
- An interesting case in Dragon Quest VI. The Hero enters Somnia Castle in the other world after discovering you look exactly like the missing prince. The chancellor, having heard that someone in town purchased noble clothes like what the Hero is wearing and he asks the name of your long dead sister. All of the available choices are wrong. Then again, it turns out that the Hero is the Prince of that world's Somnia...sort of.
- Played With in Fallout 2 by Renesco the Rocketman when you're looking for parts. After giving the password, you're asked for the second password - your only response is to cuss out the foreman for not giving you the second password. Renesco then says to relax, that there was no second password. Humorously, if you leave this quest on the backburner for too long, you can forget the first password too...The Wanderer: Marcus says... shit...
Renesco: Really? I'm sure he didn't send you all the way down here to say "shit". - Final Fantasy XIV Shadowbringers: During the 5.2 story, Ardbert's corpse is possessed by the Ascian Elidibus, who initially attempts to deceive the Scions of the Seventh Dawn into thinking he is the genuine article. You get your choice of how to make him blow his cover; offer a fist-bump ("Ardbert" asks if there's something wrong with your arm) or mention Seto ("Ardbert" acts as though the amaro is dead).
- In Injustice: Gods Among Us, the "main" universe Cyborg infiltrates the parallel universe Regime by posing as his own counterpart. Regime Catwoman notices something is off with him, and starts acting as though the two of them have been having an affair. When he tries to play along, she knows he's a fake.
- In Jolly Rover James tries to pass himself off as a pirate named Davey and is promptly stumped by Melvin asking where he and Davey were when they got drunk on a keg of rum and thought they were two young princes. It takes the help of a parrot to get past this point.
- A body-snatcher variant appears in Mega Man Battle Network 4: Blue Moon, in which Lan got suspicious when Mega Man tells him to forfeit the tournament. So Lan decided to quiz him, and the player selects the answers. For the first couple of questions, it's entirely possible to get the question right (subverting the trope), but then Lan throws out a question about the strongest Navi Mega Man has ever faced, and none of the choices given have actually existed in the series. This allows Lan to determine that Junk Man is controlling Mega Man's body. Interestingly, there is a question about Lan's Trademark Favorite Food, but while the canon answer should be "curry" (which isn't a choice given), in the English version the correct answer is "hamburgers".
- In Professor Layton and the Curious Village, the protagonists get suspicious about Inspector Chelmey when they find a newspaper article mentioning the man's love for sweets when previously he had violently objected to being served tea and cakes. They question him about this and mention his wife's name... only they give the wrong name, and he proceeds to parrot the mistake, exposing himself as an impostor.
- Tales of Berseria has a moment when Eizen (seemingly) finds his captain, Van Aifread, being held hostage. Eizen engages in some Casual Danger Dialogue about his absence and mentions his brother; Aifread purports to remember discussing that topic, and gets a fist to the chest.Eizen: I've got no brother.
- In a Yakuza 6 sidequest, Kiryu receives a call from a scammer pretending to be Taichi, one of his wards at his orphanage in Okinawa, who asks that Kiryu give a large sum of money to an accomplice in the name of helping a sick friend. Smelling a rat, when Kiryu goes to meet with the accomplice he pointedly asks if "Taichi" ever mentioned how he got the "huge burn scar" on his face (which, of course, the real Taichi doesn't have), and is almost dumbfounded at how quickly the scammers exposed themselves.
- The next game, Yakuza: Like a Dragon, has the assasssin Mirror Face perfectly disguise himself as Adachi while attacking the real one. Ichiban asks them some questions about traffic laws, where one of them is clueless while the other gives out the correct answers. Ichiban then attacks the latter, which turns out to be Mirror Face after all, who complains how the real Adachi could have ever worked at the DMV with such incompetence.
