Mecha tank

Equalist mechs are large, mechanized suits manufactured by Hiroshi Sato for the Equalists.

History
During the Metalbending Police Force's search of all Future Industries' factories, a worker handed Korra a note telling her to meet him under a bridge at midnight if she wanted to learn the truth about Hiroshi Sato. When Korra, Tenzin, and Lin arrived under the bridge, the man told them that Hiroshi Sato had a secret factory under his mansion where he manufactured Equalist weapons, including the electrified gloves. The man also told them that Sato was in the process of creating superweapons for the Equalists. Later that night, once the Police Force had found and infiltrated Hiroshi's secret Equalist factory, they discovered that the "superweapons" were actually large, mechanized robots.

Design
The Equalist mechs are large, mechanized robots made out of platinum - a form of metal so pure, that metalbending has no effect on it. The Mechs have claw-like hands which are extendable via metal cables. They are capable of producing electricity and dispersing it via these claws to electricute their opponents. In addition, the mechs are capable of shooting out spiraling disks that contain metal cables that tangle around their victims and then electricute them.
