Minerva is the goddess of the planet that Genesis sees after his last defeat. She is also an optional Boss that you can fight. She is extremely difficult to defeat. She has 1,000,000 HP and can kill you with one hit if you are not careful. She is under the final "Great Cavern of Wonders" mission. You must have at least 70,000 HP because she has an attack that does damage of at least around 60,000 to 68,000 if you have Barrier and are guarding. You can steal 99 Phoenix Downs from her though. You can use these for unlimited gil and Soldier Points. Steal the Phoenix Downs, wait for her to attack (because you will die), then sell the Phoenix Downs. They are worth a lot of gil. For the Soldier Points, use the gil you got from selling them to buy Materia, then convert it to Soldier Points. Note: Minerva can eliminate Raise status with one of her attacks.

The weak spots for the three Bosses in Sector 2 are as follows:

Colossus (Base Boss): Climb the stairs until at the very top and look down at Colossus's head. When the head opens, shoot it with a shotgun for best results (1/5 to 1/4 damage).

Enforcer (City Boss): On the machine's back near the bottom, is a circular lighted area. Your crosshairs will lock on to that area. Shoot it with a shotgun or rocket launcher for best results.

Mantis (Ruins Boss): Get close to the bug and shoot the underside. Shooting its shell will not do anything, as it deflects most of the shots. The best weapon is the Photon MG because it stops Mantis in its tracks.
