OVA
Description
Doctor Yuri is a character from the original video animation series Bubblegum Crash. He appears as a primary antagonist in the second episode of the series, titled Geo Climbers. His background is that of a Boomer scientist, a specialist in the artificial life forms known as Boomers that are central to the series' cyberpunk setting. He is directly responsible for the murder of a colleague named Professor Haynes, the creator of a unique and highly advanced sentient Boomer named ADAMA. Following the murder, Doctor Yuri stole the professor's research data. His motivation for these actions is tied to a secret arrangement with an unseen benefactor, who is later revealed to be the series antagonist Largo. Yuri's goal was to analyze and transmit ADAMA's data to this figure for purposes that ultimately serve a larger Boomer revolution.

In terms of personality, Doctor Yuri is portrayed as a calculating and treacherous figure, willing to commit murder to advance his agenda. His actions demonstrate a self-serving nature and a strong desire to avoid exposure. When his plans begin to unravel, he shows a willingness to use deadly force to eliminate witnesses and secure his escape. His dialogue and presentation have been described by contemporary reviewers as unremarkable, with some criticism directed at his character design, particularly his hairstyle.

The role Doctor Yuri plays in the story is that of a direct instigator for the episode's conflict. After the sentient Boomer ADAMA activates and flees, Yuri fears its mission to upload its data to a central super-computer in Geo City, an underground urban complex beneath Mega-Tokyo. Such an upload would provide evidence to convict him for Professor Haynes's murder. To prevent this, he deploys his own team of Boomer assassins, the Geo Climbers, to hunt down ADAMA. He also created a prototype combat Boomer designated EM-302, which he later uses in a direct confrontation. His key relationships include his role as a subordinate to Largo, for whom he is gathering intelligence. His primary adversary is ADAMA, whose very existence threatens to expose his crimes. He also comes into direct conflict with the Knight Sabers, particularly Priss Asagiri, who is protecting ADAMA, and the team's leader, Sylia Stingray.

The character's development culminates in his final confrontation with Sylia Stingray. After his EM-302 unit is destroyed in a rooftop battle, Doctor Yuri attempts to escape but is cornered by Sylia. He resists arrest and pulls a gun on her. However, her Hard Suit protects her from the attack, and she retaliates by killing him with her palm cannon. His most notable ability is his expertise in Boomer technology, demonstrated by his murder of Professor Haynes to steal advanced research and his successful creation of the combat model EM-302. More significantly, his technical actions have a lasting impact on the series; before his death, he successfully completed the upload of ADAMA's data to Largo. This information would later be used by Largo to incite a larger Boomer uprising.
