This enormous carnivorous aquatic creature capable of traveling at ultra-high speeds was infested by the X. An active hunter, Serris will strike its prey at high speeds, clocked at over 200kph, swallowing smaller creatures whole or tearing small chunks out of larger prey. Its voracity is unmatched, as Serris is also known to snatch creatures from the shoreline or on boats in the middle of the ocean. With an elongated body and flexible skeleton, Serris can also travel through tight passages at high speeds, while its thick armored plating protects it from attack. For these reasons, the B.S.L scientists had been studying Serris’ potentials as a versatile aquatic bioweapon, capable of infiltrating underwater bases or sinking ships.
In murky water, its bioluminescent underbelly glows eerily. Its weak spot is its skull, which has thinner transluscent cartilage over the brain. Serris uses this to create an iridescent glow used to attract prey and mates, depending on the patterns used. Serris is also territorial and will settle on its place of birth as its home, fiercely defending it from any intruder.
