Ultima Weapon

Ultima Weapon, also known as Atma Weapon or Ultimate Weapon, is a recurring superboss in the Final Fantasy series. It is a six-limbed bio-mechanical monster that first appeared in Final Fantasy VI as an ancient war machine created during the War of the Magi. The Ultima Weapon is the namesake for the "Weapon"-type enemies that appear in numerous Final Fantasy titles.

Beginning with Final Fantasy VIII, Ultima Weapon has been depicted as a weaker version of Omega Weapon, an even more powerful superboss that usually demands Ultima Weapon be defeated to challenge it. In later titles, Ultima Weapon has returned to being a standalone boss, often appearing alongside Omega and Shinryu in a trio of optional bosses. Ultima Weapon is also the namesake of the powerful sword, Ultima Weapon, which is sometimes obtained by defeating the monster.
