The Stegosaurus is a prehistoric dinosaur, and one of the minor characters from Fantasia's segment, The Rite of Spring. It makes a brief appearance in Heroes vs. Villains War.
Heroes Vs Villains War
When Sharptooth terrorised the dinosaurs and some heroes in a local field, Stegosaurus stood up against the evil T-Rex. Although he managed to subdue Sharptooth with his tail, he was no match against the T-Rex's ferocity, as he bit Stegosaurus on the neck, losing his senses. Stegosaurus had a brief time to open his eyes, before he shut them down, as he died from the wounds, leaving the other heroes to mourn about his loss.
