We get to see X-23, but what else will we see?
Essex is Mister Sinister, and it's confirmed we will see him
Hopefully Mister Sinister.
But what about powers?
Telekinesis, Telepathy, Technopathy, Teleportation, Healing Factor/Immortality, Size Alteration, Super strenght and Flight.
I doubt he'll be immortal. Long-lived, perhaps, but no immortality.
What do you think?
