Based on its name, The Great Tide is water based and it resembled a gigantic sea serpent with giant squid tentacles on the end of its tail though they are thousands of times larger and they can create craters and earthquakes upon impact, an angler fish luminescent bulb hanging from the dorsal ray on its head that is capable of firing immense blasts of electricity powerful enough to cause thunderstorms. The bulb can also fire powerful EMP pulses, hundreds of times the power of Leatherback's EMP.
