Eli Mills

Eli Mills is the main antagonist of Jurassic World: Fallen Kingdom. He is the assistant of Benjamin Lockwood, one of the co-founders of the original Jurassic Park, and his finance manager. He seeks to make a profit off of selling the dinosaurs trapped on the island of Isla Nublar.

History
Mills was the one who hired Owen, Claire and the Dinosaur Protection Group to go onto Isla Nublar and rescue the dinosaurs trapped on it, allegedly so they could be transported to a safer island before Isla Nublar's volcano erupted.

Accompanying Owen and Claire were Ken Wheatley and his team of mercenaries, whom Mills had hired to capture the dinosaurs for him. After capturing Blue, a raptor whom Owen had raised, Wheatley's mercenaries abandoned Owen and Claire and their friends on the island. However, they manage to flee the island before the volcano erupts and regroup on a ship filled with captured dinosaurs.

It is then revealed that Mills is working with auctioneer Gunnar Eversoll to auction off the captured dinosaurs. However, the auction is disrupted when Owen releases a Stygimoloch to thwart it.

Mills later attempts to escape with a genetic sample taken from the Indominus rex, but is killed by a Tyrannosaurus rex and a Carnotaurus sastrei.
