Isla Masacre is the northmost island of the five deaths. It is the only the island to have hybrids. After the 2015 Isla Nublar Incident, Dr. Henry Wu, was transported here, and experimentation began on the dinosaurs on the island. The Predator Culturis eventually came to the island and bred. InGen seeing these creatures took their DNA, and took out all the friendly parts. The new Perditor began to grow in species, and became invasive. Pretty soon, the island became nothing but cold calculations of life and death.
