Eli Mills

Initially, Mills appeared to be an honest man who wanted to save the dinosaurs on Isla Nublar from a volcanic eruption. He recruited former park manager Claire Dearing and animal trainer Owen Grady to join the mission. However, it later emerged that his true intentions were quite different: he planned to sell the dinosaurs as living weapons on the black market.
Mills secretly financed geneticist Henry Wu, who was working in an underground laboratory at Lockwood's estate to create the Indoraptor, a dangerous hybrid. To do this, he needed a DNA sample from the Indominus Rex, which he obtained through mercenaries.
After the volcano on Nublar awoke, Mills sent a squad of mercenaries led by Ken Wheatley to the island to capture as many dinosaurs as possible.
