I specialize in chemical and medical science, such as surgical procedures and related pharmaceuticals. I do like poisonous gasses. I have a background in genetics, since I created Limb-Grow® (alternate name: Stump-B-Gone), which is currently in military use.
We also had departments that dabble in electronics exploding smartphones to blow your enemy's head right off their necks, toyshalf of which are flammable, and candy...that has several chemicals I've created, such as Red Dye #666.
