Zamazenta resembles a magenta wolf with yellow eyes, with a bulkier frame than Zacian's and a ponytail on its head. Its forelimbs, tail, and ponytail are all a deep blue. Its body is covered in battle scars and part of one ear is missing (which is healed when it enters its Crowned Shield form). Its head and neck have thick fur resembling a shield.
The Crowned Shield form causes Zamazenta to generate a set of golden armor covering the front of its body like a shield; while the side portion normally covers its forelimbs, it can slide forward to allow Zamazenta to use Behemoth Bash or protect itself from frontal attacks more effectively. Its ponytail also grows to cover most of its backside.
By absorbing metal particles, Zamazenta can change to its other form in battle. In legends, it known as the Fighting Master's Shield due to ability to defect any attacks. Zamazenta is both feared and respected by all. By becoming a statue, it can rest for aeons; even while asleep, it can cast illusions including a projection of itself. It is believed to be the younger sibling (or perhaps the rival) of Zacian. When together with Zacian, it cancels out the power of Eternatus, even in the powerful Eternamax form.
Zamazenta's regal and majestic movements enables it to overwhelm opponents who face off against it. Zamazenta fends off the attacks of foes by using the golden shield that covers its front. The shield's strength is so formidable that even the sharp claws of Dragon-type Pokémon cannot leave a single scratch upon it. No battlefield, no matter how terrible, can make Zamazenta flinch in its resolve. It charges at enemies head on with the impregnable shield-like armor that serves as a weapon. By bashing the enemies with its full might, it is said that the power can cause cracks in the land and that the resulting shockwaves can lay waist to hundreds of enemies. By using its signature move, it can go through towering mountains.
Zamazenta is the only known Pokémon capable of using Behemoth Bash.
