These GMod Monsters are known to have science-based traits, abilities, and intellect of they're own. Others can be experienced to use genetic experiments in major results to develop Metahumans and Mutants, becoming their subordinates, or minions.
Some Freaks like them can create a deadly virus to reanimate the deceased beings into Zombies, or one that can cause them to mutate into monsters. Furthermore, they can also create medicine or cures for disease, parasites, or various cancers. In fact, they also have their own alignments as well, whether they're evil, neutral, or good.
