Beast Wars is the main title of the Transformers spin-off series in which the Maximals and Predacons battle on prehistoric Earth. It is widely known as the first major CGI Transformers animated series and follows a group of shape-shifting robot factions after a crash landing on a strange planet. The story mixes action, science fiction, and character-driven drama, and it became especially notable for expanding the Transformers franchise in a new visual style.
