In the DC comics universe, a planet called “Htrae” (“Earth” spelled backwards) is populated with bizarre versions of superheroes. A Seinfeld episode made the idea of this Bizarro World popular, where the characters encountered their opposite selves.
Ah nice to see a prompt directly related to comics, especially since I’m an avid reader and fan since I could remember reading. Here the name itself of the character Bizarro is a bizarre! He is a mirror image of Superman, with complete opposite qualities of him, like a negative(?) mirror reflection. Bizarro was Ranked #25 on IGN’s List of 100 Top Comic Book Villains.
It would be interesting to think about what my antithesis in a parallel (or even here?) world would be like. Not necessarily the evil win/parallel, as we all are flawed and not idol as Superman to have a opposite reflection, but all qualities opposite which can be tricky as right now I’m not sure myself of all my current ones and where to they fit.
