The kanima looks for a master and it's bound to the master. So i guess the master is the kanima's alpha in a way.

I don't think there's a scene where an alpha causes another alpha's beta to shift.

I think that the roar works on an omega because they could be taken in by any alpha whereas another pack's beta is bound to their alpha so only their own alpha could force them to shift. If that's the case then Derek couldn't have forced kanima to turn human when it already has an 'alpha'.

but these are just my opinions on this matter though.
