I mean what about Jaller's body? Could there theoretically be two Jallers?
I'm presuming the spirit eventually disconnects from their masks and goes to there. Or any other explanation producing an answer of no.

So there would be a time in which mask wearers could be revived in-universe, saving the need for the teleporter. Other beings would go immediately.
Or perhaps only bodies that are going to be unaccounted for can be teleported, to preserve secrecy. All kindsa ways to be a no.
Here's an attempt at an answer. Only bodies + masks would be teleported there, if the being wore a mask, and only bodies unseen by others. In the cases of Lhikan and Jaller, living people were looking at the bodies and took away the masks. In Jaller's case this was for his good, but creepily this would mean Vakama kinda killed Lhikan a second time by taking the mask away lol. The only example we have is Mavrah, who was lost from sight with both body and mask, so there's some evidence.

That would also rule out Teridax as no body remained, not even antidermis as it was instantly spread out enough to dissipate him permanently.
If the body thing isn't necessary, though, then it -is- possible Teridax went there, but that doesn't necessarily mean they would have put him into a new body. There could be standards you have to qualify for to be revived, and the worst supervillain ever probably wouldn't qualify.

BTW, I second IT's request: any chance of a transcript for that podcast?

Reading FTW.
