Meet the Invictophantasma nox, which means "unconquerable phantom of the night" (Codenames/Alias: The Sauropod Assassin, The Phantom That Wanders the Night, I. nox, sometimes spelled as I-Nox)

This hybrid contains the DNA of Giganotosaurus carolinii (base), Deinocheirus mirificus (claws and hump, slightly upright posture), Koolasuchus cleelandi (slower metabolism and contributes to head shape), and Utahraptor ostrommaysorum (tail feathers, bulky proportions). It also contains DNA from the toadhead agama (Phrynocephalus mystaceus) (head shape and weird face flaps, search it up), firefly squid (glow and RNA editing) and an unspecified species of lanternshark (glow, shark-like teeth growth pattern and coloration) of the genus Etmopterus.

Other minor genes include arapaima (durable scales), Komodo dragon (anticoagulant and iron-coated teeth), and edited limpet genes (would normally give limpets their strong goethite teeth, the hardest of any living animal, but is tweaked to reinforce the bones of Nox)

Note: They can turn their glow on and off, with the default color of those areas being grey. Invictophantasma nox has a significantly stronger bite-force than the Giganotosaurus but has a smaller and shorter head. It also borrows the Deinocheirus's claws, which it uses for self-defense from other Invictophantasma specimens. One swipe would slit a large sauropod's throat. At least 37 specimens currently exist and people hope it stays that way or less. A female specimen named the "Black Ripper" escaped her enclosure and took at least 153 lives along the way, she was ultimately euthanized. As Invictophantasma are incredibly aggressive, most of them are given anti-aggression meds to avoid another incident.

Changes from 2023 - Removed Argentinosaurus DNA, added a few new genes (since I don't have the same restrictions as last time since it was for a contest with rules)
