World Vanquisher

The World Destroyer (世界の破壊者, Sekai no Hakaisha), also known as Izuru Kamukura (AI), is the main antagonist of Super Danganronpa 2.5: Nagito Komaeda and the Destroyer of the World.

The World Destroyer is an artificial intelligence program created by Hajime Hinata who has merged with Izuru Kamukura and based off Alter Ego with the intention of awakening Class 77-B from their comatose states induced by their deaths within the Neo World Program.

Within Nagito Komaeda's illusion, the World Destroyer killed Kazuichi Soda, Fuyuhiko Kuzuryu, Sonia Nevermind, Peko Pekoyama, and several police officers. Considering the World Destroyer had to enter the minds of all the other comatose members of Class 77-B, it's possible his body count is much higher than what is known.

In the end after Nagito's illusion has been destroyed when Nagito killed himself, the World Destroyer states that he is an Alter Ego and trying to destroy all of the instability to awaken Nagito from being comatose.

Appearance
The World Destroyer's appearance is near identical to that of his creator's, Hajime. The World Destroyer has short, spiky brown hair with a large ahoge that protrudes from the top of his head. He wears a similar outfit to that that Hajime wore while a student of Hope's Peak Academy, with a black blazer and tie over a white shirt, black dress pants, and black dress shoes.

Unlike Hajime but like Izuru, both of the World Destroyer's eyes are a deep red color.

Personality
Much like how his appearance was based off Hajime's, his personality is primarily based off his alter ego's: Izuru. The World Destroyer is quite bored with the world and often neglects to show any emotion, his duty being his sole interest. He erased mental blocks with no mercy and since they had the form of humans, he looked like a cold-blooded murderer in their eyes.

When he explains to Nagito Komaeda what hope is and sees his reaction, a rare but small smile can be seen on The World Destroyer's face.

After Nagito was killed and his real-world counterpart was awoken from his comatose state, the World Destroyer's personality became similar to Hajime's. He seemed genuinely happy that Nagito had awoken and expressed a desire to explain himself and his actions to him.

Hand Pistol
The World Destroyer has the ability to use his hand as a gun. By pointing his fingers in such a way that make them resemble a pistol, he is seemingly able to fire invisible bullets from the tips of his fingers.

Using this pistol, he killed several police officers, Peko, and presumably Kazuichi, Fuyuhiko, and Sonia.

Illusionary Class 77-B
They were the target in order to destroy Nagito's world.
