Forum:Five-headed dragon vs light and darkness dragon

last saturday i had a duel with someone who plays dragons. he had a face-up five-headed and i halved it's attack with dark mist, then i summoned light and darkness dragon, now is my question, since ladd is both light and dark, does five-headed take damage and can it be destroyed by battle with it? ladd hasn't negated once sine the battle and five-headed has 2500 atk.
