Vader, fleeing is useless and you know it.  Join me!  Together we can wipe out the forces of Mechanus!
 
Brainiac flies forward to 65N60E15Z and manifests a psionic charm on the spectator, augmenting it with 2 power points to affect magical beasts or monstrous humanoids (DC 14 now).  I assume Brainiac doesn't know if Vader is an aberration, but he can't manifest that high a level of charm (it would then require 5 points, 1 higher than his level).  He'll take a shot at it, though.  If he knows Vader is an aberration (I don't know personally), then he would use a cold energy push instead.
