Yakone

Yakone was a powerful bloodbender who threatened Republic City forty-two years before Avatar Korra's arrival.

History
Yakone was the head of the criminal empire of Republic City who had a history of being arrested, though he was always 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, removing his bending. Five years after this event, he had a son named Tarrlok.

Forty-two years later, his son, 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.

When Korra was captured by Tarrlok, she followed Tenzin's advice to meditate, only to see flashbacks of her predecessor, and his allies Councilman Sokka and Chief Toph Beifong, apprehend Yakone. Few more moments down the line, Korra saw Yakone use bloodbending on everybody inside the City Hall during his trial, with Aang engaging him in combat. Aang entered the Avatar State and stopped Yakone by taking away his waterbending abilities for good. After the visions had stopped, Korra realized that Tarrlok is Yakone's son, who assumed a new identity to freely avenge his father.

Abilities
According to the testimonies of several of Yakone's bloodbending victims, Yakone used his ability on multiple occasions, all without the assistance of the full moon. During Korra's flashbacks, Yakone was shown to be an extremely powerful bloodbender, utilizing the ability on an entire courtroom, including Avatar Aang, in broad daylight, while hardly moving. His bending abilities were later removed by Avatar Aang following Yakone's unsuccessful escape from Republic City.
