Borg, altered

Star Trek: The Next Generation
Episode: TNG 252 - Descent, Part I

Thanks to the concept of individuality introduced into " Hugh" Borg in 2368, some in the collective assumed the concept too quickly and became disconnected without leadership — a vacuum filled by the maniacal Lore a year later. In contrast to the earlier automatons, these altered Borg took individual names and express emotions of vengeance, fear, and hate until the defeat of Lore and their consolidation into a benign group under Hugh.
