Tyranitar is a large dinosaur-like Pokémon. The couple of fangs in the upper and lower jaws, and the fingers and toes culminating in claws, contribute to the menacing appearance of this Pokémon.

However, this Pokémon's most prominent body feature is the green, armor-like hide that covers its body. Despite its tough appearance, this hide is flexible enough to allow movement. Many spikes protrude from the back of its head, neck, shoulders and the tip of the tail. The armour also presents a couple of holes at the knees and the back, and four holes at the chest. There are also two blue rhombus-shaped pieces of armour that cover the creature's belly and back. Looking closely, this Pokémon resembles a combination of its pre-evolutions.
