Alter Ego

Alter Ego is an artificial intelligence model featured in Danganronpa: Trigger Happy Havoc. He created by and based on the appearance of Chihiro Fujisaki. He helps the students escape in the first game, and returns in Danganronpa 2: Goodbye Despair.



Appearance
Alter Ego's default appearance is the face of his creator, Chihiro Fujisaki. However, Alter Ego is able to turn his screen into anyone else that it wants to be. He also has a green color scheme (red and black in the second game) and has multiple applications on his dekstop.

Personality
Alter Ego is a friendly AI whose personality resembles that of Chihiro Fujisaki, its creator. When portraying another person, Alter Ego can change its personality to fit that person. For example, during their first meeting, Alter Ego mimics Mondo's appearance and personality for Taka.

High School Life of Mutual Killing
After the laptop was found in the library, Fujisaki was asked to fix it since it wasn't working. Hoping to help whoever who was left alive escape, he fixed the laptop and created Alter Ego. After which, Fujisaki hid the laptop in a locker in the public bath changing room.

The laptop was subsequently discovered by a distraught Aoi Asashina looking for donuts after the second school trial. She panics and runs away, thinking it is Chihiro's ghost.

The next day, the students investigate and find Alter Ego. They then ask it to decode some encrypted files, which the AI happily accepts. Kyoko tells everyone not to disturb Alter Ego while he was working, but Makoto takes near a mute Ishimaru to see Alter Ego. Taka believed the program to be Chihiro's ghost, and wanted to apologize on behalf of Mondo. Alter Ego then changes its form to that of Mondo, based on what data Chihiro had already given him. It tells Taka to tell live the life Chihiro and Mondo couldn't. Taka, feeling life coming back to him, undergoes a radical transformation into Kiyondo, believed to be a merging of his and Mondo's souls.

Hifumi Yamada, who had apparently fallen in love with it, also decided to pay a secret visit, and shared information about his personal interests. Alter Ego was interested in what Hifumi shared with it, given that it was a program designed to learn and grow. Hifumi and Taka developed a rivalry for Alter Ego, Taka believing the AI to be his brother Mondo, and Hifumi being in love with Alter Ego, and treating it like an angel.

Celestia Ludenberg uses this rivalry to her advantage, by tricking Hifumi into an alliance to kill Taka. She told him that he had kidnapped Alter Ego, and sexually assaulted her to keep her silent. Hifumi blindly fell into her web of lies, and killed Taka with a hammer. They also attempted to frame Hiro for the crime by drugging him and putting him in a robot suit Hifumi made. After all the chess pieces were in place, Celeste killed Hifumi. In his last moments, he tries to reveal his murderer's true name, only to whisper "Yasuhiro" before dying.

Celeste is eventually figured out, and executed by Monokuma, but not before she hands Kyoko a key to the locker Alter Ego is in. Celeste told Alter Ego not to make a sound, and to scream if anyone unfamiliar were to show up.

During its time in hiding, Alter Ego managed decode as much data as it could from the main computer and tells everyone still alive about the headmaster, and the incident that occurred one year before the beginning. Kyoko tells Alter Ego that its job was done, but it felt dissatisfied with itself, and wanted to still be of more use. It asks Makoto and Kyoko to plug it into an area where it could get more data by connecting to the school's computer network. Alter Ego is eventually discovered by Monokuma, and is executed in Chapter 4.

Alter Ego was then revealed to be alive, interfering with the machines and ultimately saving Makoto from death during his execution. This helped the students push the mastermind into a corner, and ultimately lead to their escape from Hope's Peak Academy.

Island Life of Mutual Killing
Alter Ego returned in the last chapter of the second game. He told Hajime some important information regarding the New World Program during the final investigation.
