New Neutral B...or, more accurately, its alt version triggered by pressing
while he steps back before shooting fireballs:
Ground version:
Aerial version:
It is powerful, cannot be absorbed or reflected like Bowser and Charizard's fire breath, is a meteor smash (spike?) if used in the air and stops all vertical movement, so, it can be used as part of Ridley's already perfect recovery abilities. BUT vertical range (ground version)/horizontal range (aerial version) is pretty bad and there is a blind spot that can be exploited by small characters or Samus' crawl:
Until fireballs crashing the game will be fixed, this will remain default version. Default version is disabled and can't be triggered without editing moveset file, but even then, Ridley won't shoot anything or even use any SFX and GFX.
