Floyd x Veneer? That's a pairing I didn't expect to see pop up today. I've been poking around the fandom for a bit now, mostly on Archive of Our Own and a few dedicated blogs on Tumblr. Honestly, the dynamic is more interesting than I first thought. It's not a huge tag, so you kind of have to dig. The best ones I've come across treat their connection as this weird, parasitic-yet-sympathetic thing that happened in 'Trolls Band Together'. There's a fic called 'Chip of Diamond' that's still updating, and it does this amazing slow-burn of Veneer grappling with what they did while Floyd is weirdly the only one who gets the pressure they were under. The writing gets a little purple sometimes, but the character voices are spot on.
My absolute favorite is a completed one-shot titled 'Residue'. It's less romance and more intense psychological drama about shared trauma and the literal piece of Floyd's talent left inside Veneer. It's heavy, but it's so well-constructed. Avoid the ones that just make Veneer a uwu softboy immediately; the good stuff lets him be messy and vain and scared, and lets Floyd be rightfully angry before anything else develops. The tag could use more, but what's there has some real gems if you're into complex, morally grey connections.
