Fizzarolli has GERD headcanon. Thanks to my sister for dragging me back into my Hazbin Hotel/Helluva Boss phase AND opening my eyes to the fact that Fizz sings mid to high tenor???? Even with all the gravel/rasp??? My absolute fave <3
And shoutout to this diva, the only person I could find who wrote a fic using this headcanon. Honestly thought it'd be more popular, but fine.
ALSO also, I've been drawing comparisons from Corpse's song "White Tee", specifically the line "acid on my vocals that's the price I gotta pay" to this new GERD Fizz headcanon, so if somebody wrote a fanfic that had that as the title and had GERD Fizz, I'd love you forever. Otherwise I'll continue lying to myself that I'll write fanfic someday.
