Finally got to work on my Idea for an antagonist for my Merdog in San Francisco Story, Meet Dr. Snowball who is a Nerdy antagonist based off of Snowball the Bunny from the Secret Life of Pets & Dr. Walter Kornbluth from the 1984 Film Disney Movie Splash, in my Idea of the Story like counterpart Dr. Walter, Snowball comes across Sasha the Merdog while doing a deep-sea diving expedition, when he goes to report it to his fellow Scientist that Merdog exist but they don't believe him leading to him finding out that Sasha is in City of San Francisco and tries to throw water at her to expo her as a Merdog but ends up throwing water at the wrong girl getting himself beaten up by her boyfriend.

The Reason I'd pick Snowball for the Idea, Because of his Ego and his History of being an antagonist in the first Secret Life of Pets Movie and getting beaten up by a monkey in the 2nd Movie when he was playing Superhero which I might think about putting in some use for his redemption arch.

Snowball the Bunny Belongs to Illumination Entertainment.

Dr. Walter Kornbluth from the 1984 Movie Splash belongs to Disney.
