Shouichi Makise

Shouichi Makise (牧瀬 章一, Makise Shōichi), publicly known as Dr Nakabachi (ドクター中鉢), was a scientist researching in the field of time-travelling. He is later revealed to be the father (and attempted killer) of Kurisu Makise and is one of the main antagonists of Steins;Gate.

History
In college, he was friends with Yukitaka Akiha, with Yukitaka funding his time travel research early on. In the Alpha Worldlines, they were both inspired by their mentor.

After college, Shouichi got married and had a daughter, Kurisu Makise. He and his daughter would often have discussions on physics together. Eventually however, Kurisu's genius ability began to show, and she began disproving her father's theories one after another. This, combined with Shouichi's field of study, led to the man becoming a laughing stock of the scientific community and heavily strained his relationship with his daughter. He would begin taking his anger out on his wife leading to a divorce. By 2010, he had not spoken to Kurisu in seven years.

Plot
The story of Steins;Gate begins with Rintaro Okabe and Mayuri Shiina attending Dr. Nakabachi's press conference about time travel. His presentation angers Rintaro, who accuses him of plagiarizing John Titor's research. He loses his temper and yells at Rintaro, ordering him to stop. Before the argument can escalate, Kurisu pulls Rintaro out of the room. He is uninvolved with the majority of the story after this point.

Alpha Worldlines
In the Alpha Worldlines, Dr. Nakabachi cancels his press conference after a satellite crashes into Radio Kaikan, destroying the room he was going to speak in.

Beta Worldlines
At the very end of the plot of Steins;Gate, Okabe along with Suzuha Amane, time travel back to the day of the conference to prevent Kurisu's death. Okabe travels to the location of Kurisu's death and sees her enter the room with Dr. Nakabachi. It is revealed that his real name was Shouichi Makise and that he is Kurisu's father. Kurisu reveals to him that she wrote a thesis on the possibility of time travel and wanted to co-publish it with him in order to restore both his reputation and their relationship. Shouichi, while interested in publishing the thesis, refuses to share the credit with his daughter, despite not having actually contributed to the thesis. Kursisu attempts to reason with him, but this ends up further angering him, and he attempts to murder her. Okabe tries to stop him, but unintentionally stabs Kurisu himself. While Okabe is lamenting his action, Shouichi grabs the thesis and runs away.

Shouichi later takes the thesis and defects to Russia. The research documents were later saved from a plane fire by Mayuri's metal Upa, which triggered the metal detector. The thesis is later used as the basis for Russia's time travel research, contributing to the beginning of WWIII.

In the Beta continuity shown in Steins;Gate 0, it is revealed that he's more or less kept prisoner in the country to help with research and development of a time machine, and that the published version of the paper is actually an inferior copy written by Nakabachi himself to poorly mimic the theory and ridicule it among scientists. This aims to distract the rest of the world from the actual research, but also from the chaos ensuing from various organizations tracking down what remains of Kurisu - the paper's actual author, whose existence became apparent when Nakabachi's lack of actual knowledge shone through - in order to properly reconstruct the time machine.

Steins Gate Worldline
Events play out the same as in the Beta Worldlines until Shouichi attacks Kurisu. This time, instead of interfering directly, Okabe taunts the man into stabbing him instead. After stabbing Okabe, Shouichi takes the thesis and flees, later attempting to defect to Russia, like in the Beta Worldlines. However, with Okabe halving arranged things so that the Upa put into the envelope by Kurisu is a plastic one, the metal detector does not go off and the papers get destroyed by the fire, foiling Shouichi's plan.

He then swore vengeance on the Russian airlines, whom he blamed for the destruction of the research papers and was detained by Russian authorities. He was also investigated for stabbing Okabe.
