Mega Tyranitar is a dual-type Rock/Dark pseudo-legendary Pokémon.
Mega Tyranitar has more gaps in its armor than its normal form, with four new triangular holes along the sides of its neck and one on its throat. The four on its chest are now larger with the top two containing red ovals. While the spikes along the back of its neck grow shorter, the ones on its head elongate to form prominent ridges along its brows. The center spike on its head becomes a long, upright horn. Its chest plate expands, curving over its shoulders and along its back to form three long, irregular spikes on each side of its body. The scales on Mega Tyranitar's belly have now become red instead of blue and seethe with energy, enabling it to emanate more power. It gains two sharp spikes on its knees, as well as more prominent leg joints. Its tail lengthens, with the three spikes surrounding its tip growing upward and outward. Its back had split open because of the overwhelming power from Mega Evolution.
