Fire

"Fire users can crate fire out of thin air, and elemental water injures them. They can also withstand pressure and heat, and are slightly fireproof."

Core Crush
Core Crush is a move invented by none other than Aron Az Ure, where the user puts their hand on the enemy's chest, and then the hand heats up and glows, then shoots fire and mostly smoke to make the enemy vulnerable and weakened, and most importantly temporarily blind.
