Lavona Succuboso

Lavona Succuboso, introduced in the second season's episode "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. She speaks with a thick German accent, which may be considered a comedic device by her voice actress, a German native speaker, who normally does not display an accent at such a degree when conversing in English.

Her weapon of choice is a device called the "loin extractor" which is a harpoon-like projectile that attaches to the target's crotch and electrocutes them; presumably in order to collect sperm.

In "Dethrelease", Lavona and her followers have allied themselves with the Revengencers to help them attack Mordhaus during Dethklok's CD release party. She made an agreement with Edgar Jomfru that she would get to have her way with Nathan before he is killed.

Lavona arrives at the roof of Mordhaus when it is already ablaze, where she meets Nathan and a passed out Toki. She first attacks Nathan but is easily overpowered so she kisses him 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.

Trivia

 * "Lavona" is a play on phonetics for the Hebrew word for "moon". Her surname is definitely a reference to the female demon known as the "Succubus" that spends her time seducing mortal men to suck out their souls/kill them. "Oso" which makes up the latter half of her surname can be an acronym for "other significant other", referring to a sexual partner other than a spouse/partner such as a mistress.
