Doppelganger Gets Same Sentiment

Go To

When you're meeting an alternate universe version/clone/zombie/etc of someone, you're essentially dealing with a stranger. But because of your experience with your version, you may not feel that way.

For better or for worse, some people trigger very powerful emotional reactions in others. What specifically is being triggered varies — affection, protection, disgust, mistrust. However, it's very possible for the person triggering the response to be someone other than the person who originally provoked it.

Maybe the hero is meeting his Dead Little Sister's alternate-universe counterpart. Maybe he's reluctantly making himself team up with a good-aligned clone of his arch-nemesis. Maybe he's having to shoot one of his True Companions who has succumbed to The Virus and effectively stopped being the person he knew. The point is that he's still having an emotional reaction to the person because of who they "are" — even though they aren't.

In some cases, this may not have any negative effects; the recipient is similar enough to the original target that it's still the correct reaction. However, sometimes (such as if the morality of the counterpart is inverted) things may not work out so well.

Replacement Goldfish is similar, but in those cases the individual getting the benefit of the character's previous relationship are not in any way the original themselves, though they may resemble them in some fashion. Also, this trope may last a shorter amount of time (for instance, if the hero meets the Alternate Universe version of his dead sister but then has to go back to his universe).

A subtrope of Psychological Projection. Related to Unbalanced by Rival's Kid, Close to Home, Doppelgänger Replacement Love Interest, and Reincarnation Romance. It's also the reason why the Shapeshifter Guilt Trip is sometimes effective.

Compare Have We Met Yet? when you are meeting the same person, but they haven't met you from their perspective, so as far as they are concerned you're still a stranger and contrast Close to Home.

  • In Dragon Ball,
    • Goku's reaction to fighting Copy-Vegeta seems to imply this. Even knowing this isn't really his rival, Goku just can't help enjoying the fight against this Vegeta. It helps that Copy-Vegeta completely absorbed the real Vegeta's power, personality, and memory, so Goku was pretty much fighting the real Vegeta colored purple.
    • Vegeta seems to treat fighting Goku Black as another chance to beat on Kakarot, always eagerly snatching the chance to pound his rival's doppelganger.

In "Murderer, Shinichi Kudo", in an attempt to frame Shinichi Kudo, a criminal underwent plastic surgery to take on Shinichi's likeness and then put himself into a murder situation to get Shinichi convicted. However what gives away the culprit's identity; in his home a smashed mirror was found. The reason for it?

    • The Flash:
      • This is how Team Flash reacted when Harry Wells from Earth-2 first made his presence known. Being the Alternate Self version of the man who Eobard Thawne was impersonating made it very difficult for Team Flash to trust him, despite Harry's constant reminders that he was not Thawne.

Despite the fact that he was incompetent and unintelligent compared to his predecessors, Team Flash still accepts him as a team member.

So after everything that Harrison Wells had done for them, Cisco wanted "to be there for Harrison Wells."

      • When the Earth-1 heroes get captured and sent to Earth-X for execution, Earth-X Quentin Lance expresses difficulty killing Oliver, the man with the face of the fuhrer. So he opts to have a bag put over Oliver's head to make the act easier for him.

  • In Doctor Who,
    • This is explored in the two-parter "The Rebel Flesh" and "The Almost People". The Doctor comes upon a factory where employers use "flesh avatars" for dangerous work. But trouble starts when the avatars or "gangers" become sentient and start protesting their individuality to their originals. The episodes explores if the gangers should be considered real or not, with the Doctor insisting they are while the factory workers believe they are not. The Doctor experiments this using his ganger, by switching his Identical Twin ID Tag and seeing if Amy (who knows the Doctor better than anyone else) could notice the change. Turns out she couldn't, proving the ganger and the Doctor were one and the same person.
    • In "The Zygon Invasion", the shape-shifting Zygons specifically use this against the humans.

Furthermore, the Zygon commander, Bonnie, was impersonating Clara, which is implied to be one of the reasons why the Doctor was being very forgiving to her and wanted to help her pull a Heel–Face Turn.

      • Implied in "Mirror, Mirror".
