As Kory's white head sucked in heat to freeze the Thunder Bird flying above her, her red head spat that heat right back up, heating the air enough that it combusted into crimson flames. The dangerous part about a temperature dragon wasn't their cold or heat outputs, but the speed at which they can switch between them, causing everything, especially metals, to cool and heat rapidly, making them brittle.
The Thunder Bird dodged Kory's flames, but was caught by her cold breath, getting chilled until the moisture in the air started freezing on its steel plates. But it seems that the heat from the machine's powerful engines was enough to protect it from completely freezing, and something cackled inside its beak.
Isdis and Kory didn't know if it was laughing or what, but in the next second, when the beak opened up, they still couldn't tell what they were looking at. Several barrels lined together like a cylinder, spinning rapidly… that was a machine gun.
