I MYSELF HAVE A FEW MORE FIC RECS, THAT BEING:
duck and cover (https://archiveofourown.org/works/60357793) by archaghoul- a postcanon world where everything basically resets, though with all of the victors coming out on the other side (i forget what happens to the trolls but idk). all or most of the kids are slightly affected by their bodies attempting to handle their powers again!! includes: dirk and hal sharing a body (read it to understand), dirkjohn <3333, and jane not being racist!
Because Anything Could Happen (https://archiveofourown.org/works/58188181) by SemaphoricWave- alt outcome of meteorstuck where eridan and vriska both survive from the get-go, karkat’s blood powers actually being used + him getting glasses i think, and a slightly less bleak outlook on life
In Which John Egbert Is Allowed To Feel Rage For Once In His Life (https://archiveofourown.org/works/60124936) by bewarethepurpleone- basically. in order to prevent the epilogues/hs2 from happening, john agrees to work with alt!calliope to gradually “correct” the universes— by turning everyone into trolls through shenanigans on beforus. i dont know how that works. but it’s really good! the body horror aspect is handled quite well, as are some of the hangups over an ENTIRE species change.
Reallocated (https://archiveofourown.org/works/32890642) by BreezefulSkies- tales from a doomed timeline in which Hal is sent down to earth alongside baby dave! sort of a found family, little bit of body horror mixed in but for a good cause, dave being absolutely adorable, mild lobotomization, etc etc… (another good fic by the same author is Devaluated! I won’t go into detail but it’s absolutely heart wrenching if you’re a dirk fan.)
aaaand Choices, Optimism, and Deviation (https://archiveofourown.org/works/55092994) by 09Pyros_09Hydros- where a mspareader gets isekai’d into the body of eridan! that’s the premise!
