Is the inversion theory canon?
It’s like, kinda semi-canon. Calliope seems to mention it or something similar when she says: “ player abilities may also manifest in ways in defiance with their aspects if they are heavily resistant to their trUe calling. or, if corrUpted in some way by an oUtside inflUence.” You can see this inversion of abilities happen in Jade at the begging of the story, Rose when she’s Grimdark, (Vriska) when she becomes (Vriska) as well as probably a few others
