While Ann Darrow was being chased by a Foetodon, a Vastatosaurus rex appeared and killed by Foetodon by crushing it with its jaws. Upon seeing Ann, the V-Rex chased after her. Ann managed to hide on a fallen tree, but a second V-Rex appeared and attacked her. Thankfully, King Kong arrived and rescued Ann. The V-Rex attacked Kong, and was soon joined by the other one. Kong took on both V-Rexes, only to find himself attacked by a third one. Kong quickly killed one V-Rex by smashing its head with a boulder. The other two V-Rexes then tackled Kong off a cliff, causing them to become tangled in vines. Kong battled the V-Rexes through the mess of vines and tried to reach Ann. Eventually, Kong grabbed Ann and got free from the vines, dropping to the ground below. One of the V-Rexes got free as well and prepared to resume the battle. Ann retreated behind Kong and allowed him to defend her. After a vicious struggle, Kong grabbed the V-Rex's jaws and pried them apart until they snapped, killing the mighty saurian.
