Could you give me a list of perma-dead trolls? Or, trolls that are dead but some part of them is still alive somewhere (if that makes sense?)

Let’s see… So, unless there’s some way to bring Ghosts back to life in massive amounts:

-All of the Dancestors are Dead. Just like, straight-up Dead, we’ve actually not seen them alive at any point except for Meenah’s very brief flashback.

-Tavros died, but is back as a Sprite, albeit allergic to himself.

-A version of Sollux is half-dead, for whatever that may count.

-Nepeta is Dead, but she still lives on as part of Davepeta.

-Terezi is not Dead, but she’s on a journey to find Vriska and wandering the collapsing Paradox Space, so she’s at risk of not returning.

-Vriska is probably Dead, in the Black Hole, but there’s a chance that lucky Son of a 8itch is still around. (Vriska) is totally Dead though, always been.

-Equius died, but is back as a Sprite. We know he will later become part of Lord English, however we also know there’s two possible versions of ARquius- Game Over and Post-Retcon, so just like how there are two Nannasprites, it’s possible even with one fated to become part of LE, the other will still be around.

-Gamzee is, somehow, still alive. He was sucked by a Black Hole and ended up in Caliborn’s Land, to eventually become part of Lord English. The leftover half of his body may still be alive for all we know, really.

-Eridan is dead, he didn’t come back as a Sprite Post-Retcon, and given how much he hated his shared existence with Sollux, it’s likely he didn’t even board LOWAS.

-Feferi is dead, she didn’t come back as a Sprite Post-Retcon.
