PRIMASSIC: Rise of the Hybrids


In a hidden valley untouched by time, a team of rogue geneticists stumbles upon a discovery that could change the fate of Earth forever—fossils embedded with ancient primordial DNA, predating even the known Jurassic period. What they uncover is not just history… it’s a gateway to a lost world ruled by monsters beyond imagination.

Led by visionary paleogeneticist Dr. Kael Varn, the team uses cutting-edge CRISPR tech to revive prehistoric creatures, but this time, they go a step further. Merging DNA from different species—T. rex fused with venomous snakes, Stegosaurs with fire-resistant hide, raptors with chameleon abilities—they create unstoppable hybrid dinosaurs with intelligence, aggression, and purpose.

But something awakens with them—the Primassic force, an ancient biological instinct buried in their genes. As the hybrids begin to evolve rapidly, forming packs, claiming territories, and learning, it becomes clear: they are not just animals… they are reclaiming the world.

Now, as nature spirals into chaos and governments panic, humanity must confront its ultimate predator—a new dominant species born from our own ambition.

Will science save us, or has it just awakened Earth’s ancient rulers to finish what extinction began?

🐍🧱 Codename: "The Leviathan Serpent"


Species: Serpentocroca Destructor Prime


Titanocrochus Rex is the ultimate swamp predator — a gigantic, serpent-bodied crocodilian hybrid with unparalleled power, armor, and stealth. With the muscular coil of a Titanoboa and the armored snout and crushing jaws of a Sarcosuchus, this beast doesn't just hunt—it annihilates.


It thrives in murky, tropical river systems and marshlands, where it uses its 50-foot body to coil, crush, and drown prey. Its armored dorsal plating, inherited from the Sarcosuchus, deflects small-arms fire, while its heat-sensing pits allow it to detect body heat in total darkness.


Land Speed (burst): 12 km/h (short-range)


Skin Armor Rating: Resistant to bullets and fire


Capable of biting through reinforced vehicles or dinosaur armor.


Wraps around prey, crushes bones, and drags them into deep water to finish the kill.


Executes a modified crocodilian death roll while coiled — causing spinal dislocation and instant kill.


Can stay submerged for over an hour and launch surprise attacks from beneath.


Emits a low-frequency subsonic rumble that causes smaller animals (and some hybrids) to flee in terror.


Has been observed killing for dominance, not just hunger


Only known predator of Quetzaraptor Apex hatchlings near wetlands


🧪 Notes from Dr. Kael Varn's Logbook:


> "Titanocrochus Rex is not just a creature — it's a living biomechanical disaster. The swamp is no longer a place of peace. It's his kingdom, and all who enter… vanish."
