In its Hero of Many Battles form, Zamazenta is a very large magenta lupine Pokémon with yellow eyes and 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 its right ear is missing. 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. By absorbing metal particles, Zamazenta can change to its Crowned Shield form in battle.

In legends, it is known as the Fighting Master's Shield due to its ability to deflect any physical attacks. Zamazenta is both feared and respected by all. By becoming a statue, it can rest for eons; even while asleep, it can cast illusions including a projection of itself. Zamazenta is capable of flying. It is variously believed to be the younger sibling or the rival of Zacian. Its regal and majestic movements enable it to overwhelm opponents who face off against it
