Appeared in: A Bug's Life

Thumper is a minor antagonist in A Bug's Life.

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 threatens Dot, prompting Flik to defend her, much to Hopper's anger.

Many months later, when the grasshoppers return to Ant Island, Thumper attacks and chases Dot after she 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 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 beaten up by Thumper as punishment. However, Flik manages to survive the ordeal and continues his standoff. As he does, Hopper approaches Flik and attacks him, knocking him to the ground. He then tries to squash Flik's head, only to be stopped by Atta. While the rest of the colony chase off the other grasshoppers, Thumper tries to scare Dot again, but she smacks him, calls him a bad grasshopper, and tells him to go home. He then angrily roars at her, but Dim appears behind Dot and roars louder than Thumper, making him race off after the other grasshoppers while yelping like a dog.

A Bug's Life: The Video Game

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


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."
