Yakone

Yakone was an individual who threatened Republic City forty-two years before Avatar Korra's arrival.

History
Yakone had a history of being arrested, though he was acquitted of all charges. Eventually, he was convicted of bloodbending.

When Yakone threatened Republic City in 128 ASC, Avatar Aang successfully dealt with him head-on.

Forty-two years later, Councilman Tarrlok brought him up in an argument with Tenzin in order to persuade the United Republic Council to allow his task force to attack Amon head-on, just as Avatar Aang had done all those years ago against Yakone.

In the episode Out of the Past, Korra is captured and is put in a container and decides to listen to Tenzin and meditate on what she saw in her visions. Korra then saw Aang and Toph approaching then arresting Yakone for some criminal accusations and several witness reports.
