  • Legendary Monsters
  • Mythical Monsters


The user is or has the ability to take on the form of a gigantic monster, creature that is often hideous and may produce fear or physical harm by either its appearance or its actions. The word "monster" derives from Latin monstrum, an aberrant occurrence, usually biological, that was taken as a sign that something was wrong within the natural order.

Giant Monsters are remarkably variable in appearance and most have their own unique abilities and powers, the one fact that is common to them all is their immense size, endurance and strength.
