General Mandible is the manipulative and deluded supreme commander of the ant military, and the main antagonist of DreamWorks' first rendered 3D animated film, Antz. He was allowed by the Queen Ant to make the decisions of the colony. He is voiced by Gene Hackman who also played Lex Luthor. He is Cutter's former boss.
General Mandible is an ant who serves as the leader of the Queen's army alongside with his accomplice Colonel Cutter. He is a war-hungry insect with little regard for the colony as a whole (especially the army's battle against the Termites), which becomes evident when eventually betrays every ant, including the Queen but excluding his own army, by flooding the anthill in a attempt to "wash away the past".
He intends to marry Princess Bala, making her his queen and the mother of thousands of larval children, but she calls off the wedding and rejects him after becoming suspicious of his plans.
After successfully flooding the anthill, the would-be-dictator's scheme is foiled when Z, Princess Bala and the others from a ladder with their own bodies to escape from the rising waters. Mandible attempts to kill Z, but Cutter, finally having enough of Mandible's evil ways, turns against him, and instead tries to help Z, stating that is what's truly "for the good of the colony". Mandible, enraged, snaps and screams "YOU USELSS, UNGRATEFUL MAGGOT! I AM THE COLONY!" And he charges at Cutter but Z pushes Cutter out of the way, and he and Mandible fall into the flooded anthill, While Cutter saves Z, Mandible ends up smashing into an upturned root, killing him on impact.
Mandible is a nasty dictator of the ant colony. He even tricked them into going into war. He has strong feelings/lust for Bala but Bala doesn't like him. Mandible later interrogates Weaver into wanting to know where Z is located. He is described as crazy by Bala later on in the film.
- General Mandible is somewhat similar to Hopper from A Bug's Life, another computer-animated film about ants that both came out in 1998. Both are brutal insect leaders who took advantage of other insects.
- General Mandible is also similar to Adolf Hitler due to a desire to commit genocide in the name of a perfect "society" run by a superior kind of individual (for Hitler the Ubermensch, for Mandible the Soldier Ant).
- General Mandible is considered to be one of DreamWorks' most evil villains (along with Dagur the Deranged and Drago Bludvist).
- "Sacrifice. To some, it is just a word. To others, it is a code. A soldier knows that the life of an individual ant doesn't matter. What matters is the Colony. He's willing to live for the Colony. To fight for the Colony. To die for the Colony. At 0800 hours, we received word that the Termite enemy has mobilized. We have no choice but to launch a preemptive strike. You are the Queen's finest. I know you will all do your duty. I am proud to send you into battle. Dismissed."
- "Damn! Good. Damn good."
