Jurassic World had not one, but TWO good hero moments in the final battle with the Indominus.
The first one is when the Indominus is going after Owen, Zach, and Gray, trying to claw them out of the souvenir shop.
Then here comes Claire (IN HEELS!!!) who throws a flare at the Indominus, leading to the arrival of old Rexy, who thunderously roars at the usurper to her throne, challenging the Indominus to a fight. Keep in mind the age differences between the two. The Indominus was only six years old and was in her prime. Rexy was anywhere from 25-35 and was considered an older lady. This would be the equivalent of Diane Lane challenging Ronda Rousey to a fight.
As expected, Rexy puts up a hell of a fight, but due to the Indominus's size, strength, youth, and the advantage of working arms, Rexy is overpowered and is just about to be killed...
...and then comes our second hero moment, where you hear two raptor barks and see Blue come charging around the corner, lowering herself into attack position and going full speed into the Indominus (to the tune of the main theme from The Lost World), giving Rexy enough time to recover and get back into the fight. The two dinosaurs tag team the Indominus, with Blue using her speed and agility to keep the Indominus busy and allow Rexy to use her brute strength to wear the Indominus down and smash it through buildings and to the lagoon, where the Mosasaur finishes it off.
As much as people hated that scene, I found it to be brilliantly done, showing an unprecedented amount of teamwork between an old dinosaur who has NEVER liked raptors and a young raptor who is an ornery little ball of psycho behavior.
The faceoff between the two after the Indominus's death where Rexy glares at Blue, then decides to walk off and let her live said it all. Blue had the old dinosaur's respect at that point.
