Summary: In the official finale to Alphys VS Undyne's incredibly disturbing giantess offshoot series, we learn just how fucked-up things can really get in it.

And by "how fucked up", I mean as in Alphys invading Toriel's brain in just about the most painful way possible without killing her, then mind-controlling her into brutally raping her own son and husband in just about every single way possible, prompting them to then rape HER back.

Now THAT'S some fucked-up shit, Undertale fanfic or not.
