Lavona Succuboso (voiced by Angela Gossow of Arch Enemy) introduced in "Klokblocked"; leads the group "Succuboso Explosion", an extremist faction of women devoted to capturing Nathan Explosion and bearing his children, creating a race of warriors that will conquer the world. Their mantra is "We are the vessels that hold the future." They use a device called the "loin extractor" which is a harpoon-like projectile that attaches to the target's crotch and electrocutes them. It is unknown how the device actually "extracts" the loins, but when Lavona fired the weapon at Nathan during a concert, Murderface jumped in the way and was hit instead. Although the weapon did not actually hit Murderface's crotch, just his bass, he was mildly shocked and a charge was shot back through the weapon which sent Lavona flying completely out of the concert arena.
In "Black Fire Upon Us", Lavona and her followers have allied themselves with the Revengencers to help them attack Mordhaus during their CD release party. She made an agreement with Edgar Jomfru that she would get to have her way with Nathan before he is killed. She makes her way to the roof as Mordhaus burns and meets Nathan and a passed out Toki. She first attacks him, but is easily overpowered so she kisses Nathan to get his guard down. She then knees him in the crotch and pulls out the "loin extractor" to finally complete her task. Before she can fire, Toki smashes his liquor bottle over her head, knocking her out. It is unclear whether or not she escaped the inferno of Mordhaus alive.
