Shiro Sano's character which he is going to play in Kamen Rider Heisei Generations: Dr. Pacman Vs Ex-Aid & Ghost with Legend Riders is named as Michihiko Zaizen.
Zaizen is a Mad Scientist who is working on Gene medicine and also working on "Next Genome" Project. He becomes Dr. Pacman & uses the BugVisor stolen from Genm Corp. to spread the Pacman Virus around the city which also affects Akari Tsukimura.
Zaizen can also transform into a Bugster form called Genomes.
The producer Takahito Ohmori had offered the role while expecting an Ultimate Mad Scientist. Michihiko Zaizen's thinking is distorted from the inside and he will distort people's life by moving left and right.
Shiro Sano had commented that there is a dialogue in the movie "So the high school student of that time is now a Kamen Rider", when Shiro Sano was in high school, Kamen Rider 1 was airing. He felt like this dialogue was a message to him "So the High School Student of that time is now appearing in Kamen Rider".
