Thumper is a grasshopper and the secondary antagonist in Disney/Pixar's 1998 film A Bug's Life.


Physical Description[]

Thumper appears as a grasshopper with pale green skin and sharp teeth.


He does not speak in the actual movie, and is portrayed as animalistic and feral. However, in one of the bloopers, he is revealed to be intelligent and can speak. As he is roaring at Dot, he stops to rethink on how he could do better, in which he says: "I'm sorry, I'm sorry. Can we cut? It's just that I don't think I'm coming across. Hmm. Oh! Oh! I know! I know! I could lather up a bunch of spit. Ooh, ohh, that's good. I got it, J.L. All right, one more for me."


A Bug's Life[]

Thumper is Hopper's "pet," so to speak. He is feral, vicious and almost doglike (and also attached to a leash collar). Thumper is somewhat Hopper's main enforcer, brutally beating up any insect who stands up or disobeys Hopper.

When Thumper is first seen, he furiously threatens and angrily frightens Dot, prompting Flik to defend her, much to Hopper's anger.

Many months later, when the grasshoppers return to Ant Island, Thumper furiously attacks and angrily chases Dot after she accidentally bumps into him while attempting to seek Flik for help. Dot, however, manages to escape by tricking Thumper into believing she has died.

Later, Flik angrily stands up to Hopper again and, after admitting that he was the one who came up with the fake bird hoax (when it was set on fire by P.T. Flea), gets violently beaten by Thumper as punishment. However, Flik manages to survive the ordeal and continues his standoff. As he does, Hopper angrily approaches Flik and knocks him to the ground. Now it's Hopper's turn to violently beat Flik. But Hopper is stopped by Atta. While the rest of the colony angrily chase off the other grasshoppers in the ant battle, Thumper tries to scare Dot again, but she gets angry at him, furiously smacks him, lividly scolds him, furiously calls him a bad grasshopper twice, and angrily tells him to go home as she conquers her fear of him. He then angrily screams at her, but Dim appears behind Dot and ferociously roars like a T-rex at Thumper, making him race off after the other grasshoppers flying home while yelping like a dog.

A Bug's Life (video game)[]

In the video game, Thumper is the first of four bosses that Flik must defeat, appearing in the "Council Chamber" level.


  • Thumper's sound effects was later used one of the creatures in Narnia.
