Fan Casting Swarm in Edgar Wright's Astonishing Ant-Man

Fritz von Meyer was the grandson of Nazis who fled to Argentina in the final days of World War II. Although his parents and grandparents tried to instill in him the Nazi ideals, von Meyer never fully embraced them, seeing the racist portions of Nazi ideology as outdated. (This may be attributed to von Meyer's infatuation with a childhood friend, Seina Corazon, a Hispanic girl the elder von Meyers saw as a being of a "lesser race".) From a young age, he was fascinated with bees. This led him to study not only their habits but also their genetics, becoming one of the leading authorities in the field. His primary goal was to develop a strain of honey bees which were resistant to the pesticides used by farmers to protect crops from less benevolent arthropods. He found his most successful choice in the already hybrid Africanized honey bee, which due to various habits is better known as the "killer bee". Von Meyer was invited to attend an international conference on insect genetics in Chicago, Illinois; he brought several of his genetically modified bees with him, a hive of his killer bees. During one of his presentations, the genetically altered killer bees got loose and attacked him, stinging him to death as the crowd scattered and first responders attempted to disperse the bees. Eventually, all that was left of von Meyer was his skeleton. But that was not the end. Von Meyer's mind somehow merged with that of the queen bee, creating an entirely new entity. This entity, which took the name Swarm after comments made by those in the audience, drew other bees at the conference into his body. In addition, Swarm used von Meyer's skeleton to give him a semblance of form.
