Game info: Make snuffing out these flame-flinging fiends a priority, or your toast! And whoever said to fight fire with fire never met these things; your red-hot spells won't even tickle. When in danger, they'll burst into flames and really bring the heat. Douse them with a well-aimed Water or Blizzard spell to chill them out, then finish the job.

Wiki info: The Flame Core is a Pureblood Heartless that appears in Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage- and Kingdom Hearts III. The flame core has a round potbelly body with wings on the side, lavender cracks on the body, two legs dangling underneath, and fiery eyebrows over its eyes. Its top jaw isn't attached to the rest of itself and pops occasionally while spurting flames. They spout fire from their mouths and when they feel the need they will cover themselves in flames. The only way to take out the flames is with either a water or blizzard spell.
