Godzilla: King of the Monsters

Ishirō Serizawa (芹沢猪四郎,   Serizawa Ishirō?) was a scientist character created by Legendary Pictures that first appeared in the 2014 Godzilla graphic novel, Godzilla: Awakening, before making his first live-action appearance in the film, Godzilla. He returned in the 2019 sequel, Godzilla: King of the Monsters.


Dr. Serizawa is a somewhat stoic individual with a deep respect for the organisms he studies. He is very critical of the human race, particularly towards their attempts to dominate the planet and their scant regard for the rest of nature. His father taught him the value of mankind co-existing with nature and the harmony needed with nature at a young age.

Though he is secretive about his past, he loved and respected his father Eiji, so ever since he died, Ishirō keeps his father's broken pocket watch as a keepsake and reminder of humanity's hubris at Hiroshima. He believes Godzilla's existence is in the good of nature, as he appears to restore balance when it is disrupted.

After the events of 2014, Serizawa is a more respected figure in the world as governments look to him as the leading authority on the Titans. Being a reserved person, his interests include the works of the composer Wagner and poet Matsuo Bashō. Despite being considered royalty in the ranks of Monarch due to his father being one of the agency's founding fathers, Serizawa chooses not to carry a title as he doesn't believe in a higher order, only in an equal balance.


Vivienne Graham

Serizawa and Vivienne Graham are two intellectuals who are the guiding force behind Monarch. After he recruited Graham into Monarch, Serizawa noticed her brilliance in paleo-forensics and fossil analysis. He also likes how she challenges him with her scientific focus.

Serizawa and Graham continued to work together when Monarch revealed itself to the world and when their colleague Emma Russel and her daughter Maddie were abducted by Alan Jonah. During the confrontation in Antarctica, Graham was devoured by Ghidorah and Serizawa was utterly saddened by her death.

William Stenz

Understanding of Stenz's job and position in ensuring the safety of civilians during the MUTO crisis, Ishirō respects him enough to tell him about his father's pocket watch. Even though Stenz doesn't always listen to him on how to deal with the MUTOs, Serizawa sees the admiral as a reasonable man and the two share a mutual respect.


Godzilla: Awakening

Before the bombing of Hiroshima, Ishirō Serizawa was born in 1945 to Japanese sailor Eiji Serizawa and his wife. After the atomic bomb fell, Eiji found Ishirō alone in the ruins of Hiroshima and left him with his grandparents in Kyoto for the next several years.

In 1980, Ishirō visited his father in Tokyo when he called him urgently. Eiji began telling him things he said he would tell him when he was older: That he didn't work for a cargo company and in reality worked for a secretive government unit. Then Ishirō learned about Shinomura and Gojira. He attended his father's funeral the next year in 1981 and was approached by his father's old friend, Shaw. Knowing why Shaw's there, Serizawa said he's ready and joined Monarch.


In the late 1980s, Serizawa was introduced to Landsat employee Rick Stanton by colleague Dr. Houston Brooks, as whispers of the 1973 secret mission to Skull Island piqued Stanton's curiosity. Knowing a true believer when he sees one, Serizawa offered Stanton a job at Monarch shortly afterward and Stanton joined in 1989. In 1997, during a speaking engagement at Oxford University, Serizawa noticed paleobiology doctorate candidate Dr. Vivienne Graham. She joined Monarch two years later and Serizawa became her mentor. Impressed by her talent and passion, their dynamic evolved into a close partnership. In the same year, Serizawa and Dr. Graham are called to the Philippines to investigate a collapsed mine. There, they discover the skeleton of a long-dead member of Godzilla's species along with two giant spores, one of which has hatched.

In 2005, Monarch detected a sonic pulse wave signal originating from Boston similar to a previously recorded Titan song. Believing the signal to be the sign of a new Titan emerging, Serizawa, Dr. Graham, and a field team are dispatched to investigate. They follow the signal to a lab at MIT and find Drs. Mark and Emma Russell testing their prototype of the ORCA, a potentially revolutionary device that could change the face of interspecies communication. Two years later, as the couple continues to make breakthroughs with their research, they are both brought into Monarch.[1]


Nature has an order. A power to restore balance. I believe he is that power. „ 

— Ishirō to Ford Brody, about Godzilla

In the 15 years following the 1999 Janjira power plant incident, Serizawa, Graham, and a team of Monarch scientists study the male MUTO while it is cocooned and feeding on the plant's reactor. After the MUTO breaks free from its cocoon and destroys Monarch's research facility, Serizawa and Graham are taken aboard the U.S.S. Saratoga to help the U.S. military, under the command of Admiral Willian Stenz, hunt and destroy the MUTO.

After discovering that Godzilla has resurfaced, Serizawa believes that he has risen to kill the MUTO, which was his kind's natural enemy. Serizawa is proven correct when Godzilla swims underneath the Saratoga and confronts the MUTO in Honolulu. After Godzilla and the MUTO both leave Honolulu, Serizawa begins studying the MUTO's echolocation patterns more carefully. Serizawa concludes that the MUTO was communicating with a female --the dormant spore - which at this point was moved to a nuclear waste repository in Nevada. A team of soldiers is sent to the facility in Nevada and discovers that the female has hatched and is attacking Las Vegas.

When the military forms a plan to lure all three monsters offshore and try to kill them with a nuclear warhead, Serizawa protests, claiming that the bomb will have no effect on the monsters and that Godzilla is only there to kill the MUTOs and restore balance. Serizawa's pleas fall on deaf ears however and the military carries out the plan, which fails after the male MUTO steals the armed warhead and delivers it to the female at their nest in the center of San Francisco. After this, Admiral Stenz agrees to Dr. Serizawa's plan to withdraw military effort to destroy the MUTO and let Godzilla handle them. After Stenz refocused military efforts to extracting the bomb, Serizawa tells an extraction team that the MUTOs have likely laid eggs underground and are keeping the warhead there.

After the battle, Serizawa and Graham gather around the seemingly dead body of Godzilla in the ruins of San Francisco. When Godzilla stirs and returns to the ocean, Serizawa looks up in joy as the monster he has dedicated so many years of his life to studying returns to his home in peace.

Godzilla: King of the Monsters

Sometimes, the only way to heal our wounds is to make peace with the demons who created them „ 

— Ishiro to Mark Russell

Several years after the reveal of Titans to the world, Serizawa, Graham, and Sam Coleman are invited to Washington D.C. to speak to the congress about whether Monarch should fall under military jurisdiction. During the meeting, Serizawa and his colleagues were informed that Emma and Madison Russell had been abducted and decided to recruit Mark Russell to help with the rescue mission.

When Godzilla became too close to Castle Bravo, Serizawa and Mark insisted Diane Foster to not attack. Shortly after, Godzilla swam to Antarctica with Monarch in tow. It is there where the team witnessed Emma destroying Outpost 33 to awaken Ghidorah, who then had a brief battle with Godzilla and much to Serizawa’s horror, devoured Graham.

The next morning, the Monarch team received a message from Emma, who revealed that it was her plan to awaken the Titans so that humans could realize that they were never the dominant species. Serizawa scolded Emma for risking the lives of billions and trying to control something beyond humanity’s power. Despite his criticism, Emma moved forward with her plan by awakening. Rodan from Outpost 56 of Isla de Mara. Serizawa and his team then realized that Ghidorah was heading for the island and sent the G-Team for evacuation whilst the Argo lure Rodan towards Ghidorah. The plan was a success, but Ghidorah quickly overpowered Rodan and set his sights on the Argo. Just before Ghidorah could reach the Argo, Godzilla leapt out of the ocean and attempted to subdue Ghidorah, biting off one of his heads in the process. The military then intervened by deploying the Oxygen Destroyer to kill the Titans. Godzilla was seemingly killed, but Ghidorah survived the attack. Serizawa could only sit in distraught at the results.

Not long after, Monarch discovered that Ghidorah was actually an alien invader who wanted to terraform Earth into a suitable habitat by commanding the other Titans. Serizawa concluded that no other creature could fight back since the rivalry between Godzilla and Ghidorah was ancient and unique. When everyone was uncertain of what to do, Mothra appeared before Castle Bravo, revealing that Godzilla was still alive but very weak.

Serizawa, Mark, Stanton, and Chen decided revive Godzilla by traveling to the Hollow Earth via a submarine and detonate a nuclear warhead in his lair. However, the launching mechanism was damaged during the submarine’s crash and the only way to activate the warhead was by hand. Despite the danger of heat and radiation, Serizawa volunteered to detonate the warhead himself, believing that it was his purpose to revive Godzilla. He passed on his notes and research to Mark before bidding farewell to his colleagues. After braving the volcanic environment, Serizawa activated the warhead on a timer of 1 minute and proceeded to approach the beleaguered Godzilla. Serizawa then placed his hand on Godzilla’s snout and said goodbye to his old friend as the warhead exploded.
