Forgotten One

The Forgotten One is a monster created by mortal hands, sealed in the Prison of Eternal Torture due to its uncontrollable power and to the fact it nearly ended the world. In order to fight it Leon Belmont had to first obtain the Unlock Jewel found in the Pagoda of the Misty Moon, then go down the stairs across from the warp room. He is the hardest boss in the game as he has three stages of battle (organs, arm, head) with 4800HP each. When destroyed, it yields the Black Orb.

Strangely enough, it is weak against Ice, making the Whip of Ice more effective against it than the Vampire Killer. This could be related to the fact that it spews a fire beam from its mouth.

Form 1
The Forgotten One's first stage is his lower body and organs. Leon has to attack the Forgotten One's organs to tear them off one by one. Attack 1: An endless supply of maggots will drop off of the Forgotten One's body, landing on the platform with Leon. If Leon is close to the Maggots, they will arc back before lunging at him. On Hard Mode, the maggots are capable of inflicting Curse status.

Attack 2: Poison blood drips from the left side, right side, or middle of the organs.

Form 2
Attack 1: He swipes his hand across the platform, dealing heavy damage. On Hard Mode, he will sweep his arm three times across the platform.

Attack 2: He will hover his hand above the platform and slam his hand down on the platform. Alternatively, he will slam his fist down.

Attack 3: His hand lets out poison blood across the platform. After he finishes releasing blood, he will slam his hand down again.

Form 3
Attack 1: He releases a roar that shakes the room, causing rocks to crash down from above. Some rocks will remain on the platform while others will disappear.

Attack 2: He sweeps a devastating breath of fire across the stage. The rocks are the only shelter from the attack. Being hit generally results in instant death.

Trivia

 * Although the creature nearly ended the world, it is questionable how it was imprisoned if it was so powerful.


 * The Forgotten One is considered one of the more disturbing bosses.


 * The description of the maggots that crawl out of the Forgotten One's body reads "Sent to consume Forgotten Ones" which implies that there is more than one of these monsters in existence.
