If you want blood, you got it...but the Titans may not like it! There's a new leader of the Blood Cult, and her name is Mother Blood! Their mission? Kidnapping the best scientific minds from around the world to perfect their emergent-energy weapon. Their next target? Steel! And the Blood Cult has an ace up its sleeve: weaponized Source Wall energy that turns its victims into blood zombies. (As if there weren't enough blood motifs in this ish...) In the Titans' blackest night (wink), a new hero has arrived to help turn the tide.
