Can you destroy five headed dragon?

Answer 1

Yes, a light monster with enough attack can destroy it, you can also destroy it with a card effect.

for example use dragon master knight combined with metalmorph or a blue eyes white dragon with mega morph

Answer 2

try to live in real world.there were no dragons in the world,so where comes the possibility of 5 headed dragon.dragon is just a small creature like mongooses which come reptile.

EDIT: He/She was most likely referring to the Yu-Gi-Oh! card. Five-Headed Dragon is only protected from Battle Damage by EARTH, FIRE, WATER, DARK, and WIND monsters. This means that it can be destroyed by any card effects, or by Battle with a LIGHT Attribute monster. You could use cards like Mirror Force or Sakuretsu Armor as it is not protected against card effects.

Answer 3

Yes. Its only protection is that it can't be destroyed by battle, by any monster that is not Light or Divine. It can be freely destroyed by any regular monster destruction effects, as well as returned to the extra deck or removed from play.
