Ultimate Physicist

The Ultimate Physicist (超高校級の「物理学者」chō kōkō kyū no “butsuri gakusha” lit. Super High School Level Physicist) is a minor character that is mentioned in Danganronpa: Trigger Happy Havoc.

History
The Ultimate Physicist does not actually appear during the story. They are only mentioned by Monokuma when Makoto Naegi is wondering about the air purifier in the Physics Lab. Monokuma initially says that it is a time machine made by the Ultimate Physicist, which he almost immediately says isn't true. In the English version, he also says that they died during The Tragedy, though in the Japanese version he only implies it.
