Polaris

Polaris is the final Septentrion appearing in Devil Survivor 2, and the final boss in the game.

Battle
The fight with Polaris comes in 3 stages. During the first stage, Polaris is effectively immune to everything save Almighty, being capable of reflecting Physical attacks and nullifying every elemental attack, in addition to possessing several powerful attacks of his own and infinite range. Instead, the player has to weaken him by destroying parts of Polaris scattered across the battlefield, gradually reducing his offensive and defensive capabilities.

For the next stage, Polaris summons Shadow forms of each of the Demon Tamers. The player now must defeat them to proceed.

For the final stage, Polaris takes on a more bulky form, composed of 3 parts, labelled Polaris A, B, and C. Polaris A, the main body, is capable of firing a large laser outside battle to inflict Almighty damage to all characters standing on the bridge that leads to Polaris A. Polaris B, his right shoulder, possesses strong Physical strength, and Polaris C, his left shoulder, constantly summons another demon team into the battlefield each time it gets a turn. Only Polaris A needs to be defeated to end the battle.
