I'm not a pro with JW, but I did manage to keep track of each raptor and their deaths in the film after several views. I always got Charlie and Echo mixed up for the longest time.
- Charlie is the first to go down, by RPG. She has green coloration.
- Delta is thrown onto the hibachi grill. She has the blueish-grey coloration, and is the one that killed Hoskins
- Echo is chomped and then thrown away. She has an orangeish-brown stripe pattern.
After the Ingen mercenaries were ambushed by the raptors, it is Echo and Delta that are seen chasing and attempting to attack Claire and the kids in the truck. They are the two that run into the forest afterwards.
