Genetically enhanced Dilophosaurus

The Geneticially modified Dilophosaurus was a Dilophosaurus genetically engineered by Dr. Gustavus that appeared in the comics Return to Jurassic Park V and Return to Jurassic Park VI. It was never revealed what was different about this modified Dilophosaur, though interestingly it was never seen opening up its frill or using its signature ranged attack of venomous spit.

Story
This Dilophosaurus was one of the many genetically modified dinosaurs that Dr. Gustavus created to achieve the goal of a superior race of dinosaurs by breeding these modified dinosaurs and accelerating their evolution.

The Dilophosaurus became free along with many of Gustavus' dinosaurs on the night of the Isla Nublar Incident when he accidentally fired his gun at a dinosaur embryo in a jar instead of Derek, his intended target who along with fellow researcher Abby Nakajima snuck inside the cabana where Gustavus created his dinosaurs. The Dilophosaurus and the Elaphrosaurus where the only dinosaurs created by Gustavus to leave the cabana. The Dilophosaur followed the jeep of Abby and Derek as the escaped from the cabana. After Derek noticed the Dilophosaur's presence, he and Abby's jeep went off the road they were driving on due to a mud slide caused by the storm. When the Dilophosaurus arrived at the crashed jeep it found its creator holding Abby and Derek at gunpoint. The Dilophosaur then proceeded to attack its own creator allowed the two researchers to escape. The researchers also left Gustavus for death as he was mauled by the Dilophosaur he had created, but Gustavus somehow managed to survive the attack and made it back to his cabana, albeit severely injured.

The Dilophosaurus then arrived at the same cliff where the Gustavus' cabana was located after said cabana had been swept away by heavy rainfall along with all the animals that were still inside it. The Dilophosaurus found Derek grasping desperately on a tree root on the side of the cliff with Abby subsequently holding onto his leg. The Dilophosaurus began to attack Derek but the rescue helicopter that Gustavus called in arrived and rescued the two researchers.
