Those blazing claws, they tore through the flesh of them azure fire minions like a hot knife cutting through butter; the first creature that got its head sliced off was some kind of a drake that could breathe fire, and the second one was an imp with a body made of rock, yet Leo's claws could penetrate through its stony flesh with no difficulty, reaching for its blue molten core and crushed it to bits, causing instant death, leaving only piles of rocks falling upon the ground as if they were blood.
Once, I had heard that blue flames are the hottest kind of flames, with their temperature ranging from 2600 - 3000 degrees... though it seemed that Leo's solar flare did surpass such an extreme amount of heat; the Sun is 10,000 degrees at the surface, after all.
