Monstrum

Monstrum is a vile mutagenic compound created from the amniotic fluids, afterbirth, and failed chimeras that Dr. Kurokimi Chiko produces from her quirk. The highly mutative substance has the ability to improve the user's quirks, but at the same time it will activate any dormant mutations or enhance existing ones. It also heightens predatory instincts in its users and lowers inhibitions making the user more likely to follow their base instincts and become more animalistic. Though short term use of monstrum is temporary with the effects wearing off in a few days. Continued use will cause permanent changes in the user both physical and mental.

Monstrum appears as a bluish green milky substance. It can be both injected and imbibed orally to gain its effects. Though injection is the quicker and more potent option. The drug is also highly addictive, and when the effects wear off it is often accompanied by general soreness,pain, and a strange milky green sweat as the body reverts from its transformed state.
