Not sure. I guess we'll have to wait until they say their names or until Jay mentions them.
Well maybe, we can recognize the voices.
I'm pretty sure the Sons of Garmadon Jay is Jaybird 84, Kelly Metzger's voice. High pitched compared to the others.
These are my assumptions
s1 - Dee-Jay 81 - Paul Dobson
s11 - Beta Jay 137 - Andrew Francis
s8 - Jaybird 64 - Kelly Metzger
s4 - Jay Walkin 235 - Bill Newton
(S8 is DEFINITELY kelly metzger, I think s1 sounds most like paul dobson and s11 jay reminds me of morro sometimes depending on intonation, so I'm guessing he's the one that's voiced by andrew francis.)
I think Dee-Jay 81 and Beta Jay 137 are opposite. But thanks for the information we now fully understand all but two of them.
My reasoning was this:
I think the lowest voice is paul dobson, which looks most synced to s1.
s8 jay is kelly (obviously)
I think Beta Jay 137 just SOUNDS a lot like morro sometimes. There were two moments where I thought he sounded slightly too familiar - I've just rewatched to find them back. The first is when he says "your stamina stats are probably quite low" and the second is when he says "super backflip flying kick," about halfway through. I'm not sure what it is about them, maybe it's the accent or the intonation, and it might just be coincidence, but it makes the most sense to me.
That leaves s4 jay, which is probably bill newton (as he usually only does small extra voices and that jay only gets one line).
It'd be really nice if some of the VAs could actually confirm/deny this (or if we get to see them again in a later episode) though!
