[Star Trek/DC Comics]The Borg have caught Superman while he's weakened, whether by a red sun/simulated red sun radiation, or Kryptonite, and assimilated him. What is the best case and worst case scenario we can expect?

Best case, Superman's Kryptonian physiology rejects the Borg tech when he's re-powered and he wipes the floor with them.

Worst case, Superman becomes repowered with the Borg tech in him and still part of the collective.  The Borg manage to determine how Superman's powers work and disseminate this data across the collective, leading to more Super-drones.  At first, Kryptonite and red sun radiation keeps a lid on this, but the Borg quickly adapt defenses to these.

After that, it's all over as these new Superborg overrun worlds in hours.
