Ruiner is a respawnable boss encountered in the Bounty of Blood, a downloadable content (DLC) add-on for Borderlands 3.


Ruiner is a massive creature of doom, origins of which are unknown. In her attempt to seize full control of Gehenna, Rose had it hatched out from the blackstone stolen from Vestige. It serves as the final boss of the DLC and can be found in the Crater's Edge.
