Kraken

The Kraken is one of the great primordial "Titans" - enormous beasts from the elemental planes who wield power sufficient to challenge even the gods. The kraken played a major part of The Shattering by destroying the city of Neprius and slaying one of the resident gods, Blipdoolpoolp. The creature is still alive to this day, but has not shown much interest in attacking the inhabitants of the Elemental Plane of Water for quite some time.
