LoreThis card cannot be Special Summoned except by removing from play three different Sea Serpent-Type Monster Cards on your side of the field; then you can Special Summon this card from your Fusion Deck (You do not use "Polymerization"). This card cannot be destroyed as a result of battle. The original ATK and DEF of this card become equal to the combined original ATK and DEF of the Sea Serpent-Type Monsters used to Special Summon this card. As long as this card remains face-up on the field, increase the ATK and DEF of all Sea Serpent-Type Monsters by 800 points. Once per turn, by Tributing 1 WATER or Sea Serpent-Type monster on your side of the field, this card gains ATK equal to that monster's original ATK, until your opponent's next End Phase.
