Leon

Leon was a worker at the Velociraptor paddock. Movies=

Jurassic World
Leon was on duty when Vic Hoskins was watching Owen Grady working with his raptors. When a pig used to feed the raptors got loose inside the pen, Leon attempted to use a noose on the end of a long pole to retrieve the animal before the raptors ate it. He was too late. Although he got the noose around the pig's neck, a raptor snatched the pig and jerked it away. Leon, holding onto the pole, got pulled off of the elevated walkway he was standing on and fell into the enclosure with the animals.

He was immediately surrounded by Blue, Delta, Charlie and Echo, who hissed and snarled fiercely at him. As he scooted away from them, Owen opened the door and entered the paddock, and was able to successfully make the four raptors back down, allowing Leon to make it safely out of the enclosure before leaving, himself, warning Leon to be more careful next time.

What eventually happened to Leon is unknown. He doesn't appear to have been among those killed when the Indominus rex turned the raptors against the humans, so it's possible he was among the employees and visitors evacuated from Isla Nublar.
