Danganronpa 2: Goodbye Despair
Izuru Kamukura, after being captured by the Future Foundation along with other Remnants of Despair, downloads AI Junko into the Neo World Program.

Chapter 6 - This is the End, Goodbye Academy of Despair
Once Hajime Hinata and the rest of the survivors reached the final trial and the choice to either graduate or live on the island forever, Junko pretended to be Makoto Naegi and force them to Graduate. After the survivors realize they are being tricked, Junko reveals herself in the form of a giant body and communicates with them through the use of a giant cell phone which displays her. As the trial carries on, Makoto Naegi, Kyoko Kirigiri, and Byakuya Togami appear in the game and Junko's full plans are revealed to the cast.

Junko planned to use the Graduation Ceremony to upload her own AI into the comatose bodies which would effectively revive her in their bodies and to also keep the members of the Future Foundation locked in the game forever as she is the one that must allow a student to graduate.

Junko's overall goal, in the end, was to fill the entire world with copies of herself that she dubs "Junkoland". Junko spreads her despair into the survivors and manipulates them into wanting to graduate but with the help of Chiaki Nanami, Hajime is able to become awakened and put an end to her despair. With this, the eight are able to activate the Forced Shutdown, which put an end to the AI Junko for good.
