Snowball

Snowball is the main antagonist-turned-deuteragonist of The Secret Life of Pets and one of the main characters in RS101: The New Academy. He is also the husband of Queen Waterva Wa-Nabi.

Personality
Snowball is known for being insanely cute, but also literally insane due to the trauma of being abandoned by his owner. He has a hate for pets and their owners. Snowball initially fits the classic "evil mastermind" stereotype, wanting to dominate the world using The Flushed Pets. Snowball is also incredibly eccentric and manipulative, with a tendency to rely on one-liner comedy. However, in the end, he had a change of heart, as he was now a member of the D101 family.
