Stegosaurus is a pre-historic dinosaur and one of the minor characters from Fantasia in the segment, "The Rite of Spring". Stegosaurus makes a brief appearance in Heroes vs. Villains War.
Heroes Vs Villains War
When Sharptooth terrorises the dinosaurs and some heroes in a local field, Stegosaurus makes a stand against the evil T-Rex. Although he manages to subdue Sharptooth, with his tail, he is no match against the T-Rex's ferocity, as he bites Stegosaurus on the neck, losing his senses. Stegosaurus has a brief time to open his eyes, before he shuts them down and dies, leaving the other heroes to mourn about his loss.
