No! Bad grasshopper. Bad grasshopper! Go home!
―Dot overcoming her fear of Thumper and telling him to go home

Thumper is the secondary antagonist of 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. He communicates with sounds of different animals such as a monkey and a dog. However, during the outtakes, he is very neurotic as he speaks when his roar didn't work right while trying to scare Dot.


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 to or disobeys Hopper. In particular, Thumper has a rivalry with Dot.

When Thumper is first seen, he is straining at his leash two grasshoppers are holding onto and snarling, wanting to eat the ants. Thumper lets out a scream and goes for Dot. Dot gasps in horror and runs, but she is picked up by Hopper. Hopper teasingly brings a whimpering Dot closer and closer to Thumper, dangling her in the air. Hopper continues to carry Dot even closer to a screaming and snarling Thumper until Flik orders Hopper to leave Dot alone. Hopper comes over to Flik and asks if he wants Dot. Flik did not want Dot. So Hopper tells him to get back in line before letting Dot go.

Many months later, when the grasshoppers return to Ant Island, Thumper attacks and chases Dot after she accidentally bumps into him while attempting to seek Flik for help. Dot slows him down by hurting him with a spiky plant; he catches up and knocks her down into the riverbed. Thumper, believing she is dead, laughs and flies off. However, Dot is finally able to fly now, and she reappears after Thumper leaves.

Later, Flik stands up to Hopper again and, after admitting that he was the one who came up with the fake bird (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 knocks him to the ground. Before Flik can get beaten up by him, Atta stops Hopper. While the rest of the colony chase off the other grasshoppers, Thumper tries to scare Dot again with monkey pants, but she smacks him, calls him a bad grasshopper, and tells him to go home. He then angrily screams at her, but Dim appears behind Dot and lets out a T-Rex roar at Thumper, scaring the wits out of him and making him race off after the other grasshoppers while making a noise like a cartoon dog yelping.

A Bug's Life (video game)

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


  • Thumper's ironic name was completely intended. John Lasseter named him after one of his favorite Disney characters, Thumper from Bambi.
  • Though Thumper rarely speaks, as Molt is desperately trying to hold his leash. When he actually speaks in the outtakes, he is voiced by David L. Lander, who has also voiced Smarty the Weasel.
  • In one of the Outtakes Thumper asked for "another take" at roaring at Dot. "One more take JL!"
  • In the video game version, his only line is "PSYCHO! THAT'S WHY THEY CALL ME THUMPER!"
