Dinoshroom

Powers
Dinoshrooms are a combination of Dinosaurs and Fungi. When the Dinoshroom was chasing Drake Pansymar, it was quite close to him. This shows how fast this creature is. Furthermore, his muscle build, such as chest, legs and tail also demonstrate this animal is strong/powerful. We can see that this creature was made for Battle Purposes. It has a range of sharp teeth, pointed edges on its chest and shoulder, and has sharp finger nails. In addition, the Dinosaur's nose has about five holes. We can assume that since we can not see the creature's eyes, the Dinoshroom therefore relies on it's multiple robust nostrils. Moreover, it has been shown in the comic that the Dinoshroom is capable of flying. To be specific, it can burst out huge flames out of its lower shoulder. Imitating a kind of rocket powered jetpack.

Theories
It is strongly suggested that this creature is one of the examples of being a mutant. It has the natural ability to shoot out fire to fly, like a rocket/jetpack, and it has organic armour grown out of it. It is also quite evident that the characteristics of this creature (being a mushroom and a dinosaur) could be the cause of a combination of radioactivity and the enviroment (which was the Mushroom Forest).
