Deus

Deus is an antagonist in Xenogears. It is fought twice, once in Mahanon, and again in its core. It is referred as a god by many of the Xenogears world's inhabitants. But in reality, it is a biological weapon created by humans in ancient times on another planet. Although it is the penultimate boss, the boss after Deus is extremely easy, it is considered by many the final boss of the game.

Appearance and Personality
Deus has several forms. Its first form, known as "Omega 1" was seen on the display screen of the Eldridge in the opening scene. This is the form that the party fought in Mahanon. After being defeated in its first form, and its body was move to Merkava, Deus takes the form of a large dome with many eyes. After Merkava rises from the earth, Deus begins terraforming to fuse with the planet. When confronted by the party inside its body, Deus is surrounded by four pillars with the center being its true body. Due to being an an artifical intelligence, Deus displayed little to no personality.
