Battle at the Equalist factory

The Battle of Future Industries was an early battle in the Equalist revolt. It took place in the Equalist factory located underneath the Sato estate. The battle took place days after the Equalist raid at the Pro-bending Arena. The battle occured when Avatar Korra, Chief Beifong, Tenzin, and metalbender police officers executed a raid on the hidden factory.

History
A few days prior, Avatar Korra eavesdropped on a conversation Hiroshi Sato, owner of Future Industries, had on the phone, saying that they would be ready to strike by the end of the week. Alarmed, she reported her findings to Chief Beifong and Tenzin. Due to the death of Sato's wife at the hands of a firebender, they deemed it as a idea worth looking into.

The next day, the mansion was raided and Chief Beifong and Tenzin interrogated Sato. Stating that it was all misunderstanding, he explained that since his biggest rival, Cabbage Corp, had been closed due to equalist equipment being found in its factories, it would be the perfect time to launch a new line of Satomobiles to the public. However, he did agree to have his factories searched by police. The searches wound up yielding no evidence of any involvement with the Equalists, save for the last of the searches, when Korra was given a summons to meet a mysterious man under the Silk Road Bridge at midnight for information regarding Hiroshi's involvement with the Equalists. She attended this, along with Chief Beifong and Tenzin.

They were informed that Hiroshi was involved with the Equalists and had framed Cabbage Corps. He revealed that Sato had created and supplied the Equalists with the electrified gloves, and that he was working on an even more devastating weapon. They were also told that there was a secret factory located underneath the Sato's mansion. The mansion was raided and a tunnel was found in Hiroshi's workshop behind his home. Korra, Tenzin, Lin Beifong and several metalbender cops entered the tunnel and found a massive factory with banners of Amon on the walls. They also saw the brand new weapons - mecha tanks.

Battle
At that moment, a large door shut quickly, trapping the benders inside the factory. Lin attempted to metalbend the door open, but to no avail. Hiroshi Sato then revealed himself to the group and told Lin that the door was made of platinum, effectively rendering their metalbending useless. Hiroshi and several other Equalists surrounded them as Lin realized that the informant she, Tenzin, and Korra had met had set them up.

After Korra angrily branded Hiroshi a no-good Equalist and demanded he come out, he declined and began attacking the benders. The metalbender cops were able to leash two of the mecha tanks, momentarily stopping them with their metal cables. Lin began attacking one mecha by using hidden blades in her armor to stab the control area of it. Korra attempted to use firebending to bring Hiroshi's mecha down, but was unsuccessful. Tenzin started to use airbending attacks against Hiroshi's mecha which succeeded in driving him back. The metalbender cops were disabled by the mechas using their electric claws to electrocute the officers. Lin was then knocked out by an electrically charged cable shot from a mecha. Korra suffered the same fate at the hands of Hiroshi's mecha, but Tenzin saved her from being slammed into the ground. The airbender then charged the mechas on his own, using advanced airbending techniques to ward off the attacks. He was knocked unconscious by Hiroshi's weapon.

As the industrialist ordered the Equalists to load the benders into tracks to be taken to Amon, Mako and Bolin snuck in from the side after hearing noise from the battle on the surface. As they gathered up Tenzin, Korra, and Lin to take them to safety, they were halted by Hiroshi and the Lieutenant. Mako then angrily noted to Hiroshi that his friendliness toward them was all to gain their trust. Sato confirmed it and told him that the hardest part was watching his daughter fall in love with a "firebending street rat" like him.

As Hiroshi and the Lieutenant advanced toward them, Asami called out to her father to stop. Hiroshi then confessed to his daughter about his connection with the Equalists and attempted to justify his affiliation with the organization. Sato then offered Asami to join him, giving her the chance to take an electrified glove. Asami appeared to accept his offer, much to Mako and Bolin's dismay. She then told her father that she loved him and electrocuted him with the glove. The Lieutenant then proceeded to attack her, but she defeated him without significance effort. She, along with Mako and Bolin, carried Korra, Tenzin, and Lin out of the factory.

Effects
As the escapees fled in a police airship, Lin revealed to Tenzin that she was resigning from Chief of Police because of the guilt in knowing her metalbender cops were being taken to Amon. After Tenzin urged her not to, she told him that she was going to rescue them and take down Amon her way, even if it was "outside the law." Korra told Mako, Bolin, and Asami that they were welcome to stay at Air Temple Island.
