YMMV: Fringe S02 E14 "The Bishop Revival"
- Complete Monster: The artificially youthful Nazi Mad Scientist Alfred Hoffman was an unrepentant Sociopath who survived the war and went into hiding. Decades later, Hoffman resurfaces with his greatest creation: a toxin he engineers to target specific genetic strains. He first tests it on a Holocaust survivor and her family at a wedding. He later tests it on a cafe to confirm its effectiveness and the fact he can use it to kill anyone not part of his "Master Race." Before Walter Bishop turns the toxin on Hoffman himself, Hoffman is about to deliver it at a human rights conference to kill everyone there.
