A New Beginning: Spyro uses his full power to blast Cynder so hard he knocks her out of the Dark Master's control
The Eternal Night: Spyro is exposed to Malefor's evil power, turning him into Dark Spyro. Dark Spyro then proceeds to turn Gaul to stone and shatter him to pieces.
Let's not forget when Spyro flips out after Ignitus's apparent death in the Burned Lands only to have Cynder snap him out of it with a calm "Don't do this."
Dawn of the Dragon: The entire Final Battle is one long one. Spyro and Cynder fight the Big Bad first in a dog fight, then while falling down a volcano to the center of the planet where they finally defeat him in a Beam-O-War.
Also, Ignitus gets one in the first game when he shows just what a fully trained dragon can really do to a bunch of apes. Another group of them end up suffering this in the second game in another such moment during the Ape raid on the temple.
Sparx finally snapping and punching out Sniff in the Sky Pirates arc of the second game.
