Dawn of the Planet of the Apes: Firestorm
Five days after the Battle on the Golden Gate Bridge, he joins Caesar, three chimpanzees, Rocket, Dallas and Sam, two fellow orangutans, Musang and Eastwood, and one bonobo named Koba as they distract a helicopter. Together they draw the helicopter away from the main troop, only to find more humans on the ground with both tranquilizer guns and regular guns.
Caesar ordered Keling and the other orangutans to carry the other apes on their backs as they were better at finding branches to swing from day or night, and they needed the edge since it was night time. Keling follows his orders and personally carries Caesar on his back as they make their escape. After the apes lose the helicopter and humans on the ground Caesar orders Keling to let him down and Keling obliges.
After regrouping with the main group of apes, Keling helps the apes in their search for food by telling Caesar that fruit can sometimes be found in metal or plastic cans made by humans. Keling eventually escapes the humans' grasp and joins Caesar's newly founded colony.
