Caliban
In the comics, Caliban’s main mutant ability is to sense and locate other mutants. We have already seen him in a very minor role in X-Men: Apocalypse, portrayed by another actor. However, in the comics, Caliban has other abilities as well, including the power to control the emotions of others.
In the Old Man Logan storyline (which is followed, at least in spirit, in Logan), Wolverine is tricked by Mysterio into killing the X-Men. Of course, Fox doesn’t own Mysterio, so the studio might go another route.
Caliban is rumored to be one of the allies of the mutants in Logan. But this is just a rumor. So what if he is the one to blame for Wolverine’s current state of being? What if Caliban influenced Logan and, in a fit of rage, he killed all of his friends?
This is a possibility that should be taken into account at this moment. Especially since it doesn’t necessarily mean that Caliban will stay evil for the entire duration of the film (there are a few quick shots in the trailer in which it appears that he is being tortured by the Reavers).
Another interesting thing is that Logan seems to struggle at one point in the trailer, as if trying not to kill someone. Could this be the moment when all of the mutants become gone?
