The electricity-emitting section of the Millennial Pearl Seahorse, and its regalia, the symbol of its surpassing might—now snapped off amidst a clash against a mighty challenger.
As the greated predator that can arise from seahorses, this being's evolutionary journey is not the same as that experienced by other Fontemer Aberrants. It did not start from a large base form before growing larger and stronger, but instead grew limbs and a horn that have no place on an ordinary seahorse. Even its musculature and skeleton have changed. It really seems to resemble a fantastical beast from legends of yore more than its original shape. In the imaginations of poets and authors, even seahorses can frolick upon the earth.
