Miaplacidus was an amphibious animal species while lived on the Ozymandias. It was engineered by MTHR-248 from human and spinosaurus genes.[2] Only one specimen is known to have existed, and was killed by S.O.A.R. member Patrick Tyler shortly before the ship's destruction in Earth orbit.


Miaplacidus was created by the M.T.H.R. as part of a pre-record order by Captain Satoko Evans to create lifeforms to inhabit the planet a2, following the crew's death from lethal radiation poisoning. Though MTHR was tasked only with cloning the crewmembers who had submitted genetic samples to the DNA laboratory, it began to incorporate stored dinosaur DNA to the samples after discovering reptilian DNA was less affected by cosmic radiation.[3] Miaplacidus was created as a follow-up study to engineer an amphibious hybrid to colonise the planet's waters.[2]

When MTHR-248 began an attempt to destroy the front modules of the Ozymandias, Miaplacidus attacked the Energy Core and flooded it during an fight with Patrick Tyler. It successfully escaped to the MTHR Sector before the Energy Sector was destroyed, and fought him again in the MTHR Room when it was intentionally flooded in an attempt to kill him. Miaplacidus was however killed in the confrontation.



Full render of the Miaplacidus

Miaplacidus shared some physical attributes to the Spinosaurus, such as long jaws filled with sharp teeth, long grasping arms and tall spine. The creature also sports large fins covering its head, akin to a frilled lizard. Miaplacidus is also capable of spitting high-pressure jets of water as a long-range attack.[4][excerpt 1]



The Miaplacidus roaring.

Miaplacidus serves as a boss enemy fought in the M.T.H.R. chamber, and should not be confronted directly. Its primary attacks are biting and using water blast, while at some points it may also use its tail to whip. WASPs are very useful in this fight since Miaplacidus constant movement means that the player needs to constantly dodging its attacks.

Often times, the creature will swim in the water surrounding the battle area. The creature will sometimes show itself and spray a powerful water blast, dealing high damage to the player.
