so like is inversion actually a thing in the comic or is it just an idea people came up with that just happens to explain somethings in the comic. It's just out of curiosity it's just that I can't exactly recall anyone potentially inverting save for Rose (who just became Void cuz of horrorterrors)

Inversion is a headcanon and theory of some regarding an actually noticeable thing that happens in the comic with certain characters, but which has been expanded by the current Roleplay Theory. It’s still likely not perfect? But basically- Instead of Classpects just… Switching completely and inverting, it’d seem characters just simply act like people they look up to, to the point of emulating their Class, and sometimes, even their Aspect. Corruption forces them to act against their own natural tendencies, which in turn can also shift their Classpect.

A notable example is Vriska, whose admiration of Mindfang leads her to act out the role of a Sylph of Light for a GOOD chunk of the Webcomic. She’s always trying to be there, she’s fussy and meddlesome, Making things happen, being compared to a fairy… She also spectacularly fails at this role, specially with Tavros, to the point of vilifying herself, at which point she starts to think back on what she’s done wrong.

Rose’s also a clear example, of acting like a Witch of Void, but this time instead of admiration for a person, it seems to be for the role and influence by the Horrorterrors. There’s a lot to consider with different characters and Roleplay, but it opens the doors to a lot more versatility than Inversion, and it makes more senses because… We’re explicitly shown Trolls inherit the karmic fate of their Ancestors, and come to emulate them, and in acting like these Ancestors, they’re acting a different Class than their own.
