The ant protagonist in A Bug's Life is Flik. He is an inventive but accident-prone worker from an ant colony forced to provide food for the grasshoppers each season.
Flik's attempts to improve life for the colony repeatedly cause trouble, but his creativity eventually leads him to challenge Hopper, the grasshopper leader. Believing he has recruited powerful warrior insects, Flik brings a group of circus performers to the colony. They are not trained fighters, yet their performance skills help the ants discover that cooperation and courage can defeat intimidation.
The other names are important characters but not the protagonist. Hopper is the main antagonist, Dot is the colony's young princess, and Atta is the older princess who is preparing to become queen. Released in 1998, A Bug's Life was Pixar's second feature film and was directed by John Lasseter, with a story developed by Lasseter, Andrew Stanton, and Joe Ranft.
