Dinocroc is a hybrid of Suchomimus and Sarchosuchus Imperator, and resembles a spinosaurid theropod. It is much smaller than the famous Spinosaurus, its size being closer to that of either Baryonyx or maybe a real Suchomumus. The other one from Dinocroc vs Supergator looked like a hybrid of Stratiosuchus from Brazil & the South American Spinosaur Irritator.
Dinocroc is just like many other antagonistic predators are portrayed in fiction: always hungry and having a specific taste for humans. But what made it dangerous is its tenacity and persistence to after protagonists and other humans who stood on its path, which equal to its insane endurance. As Dinocroc is said to be a gene-spliced mixture of crocodile and a dinosaur ancestor of the modern crocodile, it is highly aggressive, creating a sort of squared version of it's own instinctual ferocity. While the Dinocroc appears primarily driven by hunger it also show a clear aggression for all living creatures no-matter how much it eats. The methodical picking off of all humans no matter how far they run indicates some sort of blind hatred for all things regardless of it's innate instincts. Dinocroc is also revealed to be extremely territorial as witnessed in the cross-over film between it and Supergator.
Powers and Abilities
Dinocroc has the classic ability set of a Jurassic Park styled dinosaur as well as other predatory monsters in other film: very strong for its size, fast, agile, and extremely hard to kill.
At the end of the movie, Dinocroc was hit by a train and had a railroad spike driven through its eye into its brain. However, at the end of the movie, it seems to be alive and well. This could be attributed to it having an offspring, as the novelization seems to suggest.
Battle against SupergatorThis film features Dinocroc, who serves as one of the two main antagonists in the film, the other being it's arch rival, Supergator.
In the movie Dinocroc vs Supergator, another Dinocroc is seen. It looks fairly different here and has different origins. It spends most of the movie terrorizing a local town until it comes to blows with another super-crocodillian called the supergator. Being that this creature was smaller, and built more like a real alligator than a dinosaur, it was dispatched fairly easily. The Dinocroc was then unceremoniously killed by a saw dust explosion.
