As the leader, Lightning Bolt Zolt worked to make the Triple Threat Triad one of the most prominent organized crime syndicates in Republic City, using fear and violence to extort shopkeepers, steal shipments, and blackmail public figures. Around this time, the crime boss met Mako, who was working for the gang as an accountant, and taught the young boy lightning generation and redirection.
In 167 AG, Zolt, along with Shady Shin, Mako, and Bolin, watched a pro-bending match featuring the Black Quarry Boar-q-pines, inclusive of legendary competitor Toza, whom Shin had paid off to take a dive. However, after the pro-bender completed a knockout, Zolt glared angrily at the ring while Bolin revealed that he had told Toza not to throw the match. Outraged about this revelation, Shin stormed off, chasing the fleeing siblings. Zolt followed the group, and eventually found his recruiter facing off against Mako, Bolin, and Toza in the latter's gym. Slamming his fist into the wall, the crime boss angrily put a stop to the fight. Zolt proceeded to chastise his associate for fighting kids, and the pro-bender for costing him money and not acting honorably. Zolt grimly watched as Toza offered the young brothers a chance to live in the Pro-bending Arena and walked away after they accepted the offer.
At the beginning of the Anti-bending Revolution in autumn 170 AG, Lightning Bolt Zolt was among five bending mobsters taken after the Equalist raid on the Triple Threat Triad's headquarters. During an Equalist gathering, Amon, who recounted Lightning Bolt Zolt's many acts of oppression over nonbenders, presented the bound crime boss to the booing crowd of nonbending Equalist supporters. Zolt, unmoved and annoyed by the situation, simply said that the nonbenders should "boo [themselves]." Much to his surprise, an Equalist proceeded to release him, while Amon challenged him to a duel to keep his bending. At first Zolt was confused that someone, especially a nonbender, would face him out of free will, but he soon grinned and accepted the challenge. Self-confident, he predicted that Amon would regret freeing him.
Lightning Bolt Zolt started the duel by sending multiple rounds of fire blasts at Amon, who dodged every attack, consequently nearing Zolt after each maneuver. Realizing that he needed more to kill the Equalist leader, Zolt enhanced his attack on Amon with a steady stream of lightning. However, the revolutionary leader easily overpowered him while evading all of his attacks. Amon caught Zolt's arm to control his lightning, and placed two fingers on his forehead with his other hand on the back of Zolt's neck, stripping him of his bending. In an impressive spectacle, Zolt's stream of lightning degraded into firebending and finally extinguished. After taking his bending, the Equalist leader let go of Zolt, who collapsed onto the ground. The crime boss, however, quickly regained his consciousness. Refusing to give up, he attempted to firebend at Amon, but to no avail. Shocked of the loss of his bending abilities, the Triple Threat Triad leader asked Amon what he had done to him. The revolutionary leader told Zolt, "Your firebending is gone. Forever." In the course of the next six months, Zolt was replaced by Viper as the triad's leader.
Lightning Bolt Zolt is known to be a blunt and often merciless man who does not hesitate to cut his enemies down. Tremendously self-confident, he is unconcerned of what others think of him, evidenced by his callous attitude toward the booing nonbender crowd that gathered at Amon's rally. He also showed to be courageous and unyielding, as he accepted Amon's challenge without hesitation and even tried to attack the Equalist leader when he was defeated and lying on the ground. However, Zolt was deeply shocked when realizing that his firebending was gone, hinting that much of his self-confidence depended on his powerful bending.
Zolt was very skilled in the art of firebending, having mastered the difficult and dangerous techniques of lightning generation and redirection at a high level, and was one of the few known firebenders able to generate lighting at a fast speed. Zolt also proved to be a capable teacher, as he passed his lightning techniques down to Mako. The extent of his abilities became apparent during his duel with Amon; Zolt employed quick bursts of fire before resorting to his powerful lightning. He was able to maintain a steady stream of lightning, using it to cut through multiple metal structures with ease. The crime boss is also relatively physically strong, as he was able to stand up immediately after Amon's removal of his bending, and also regained consciousness very quickly.
Zolt's line after Amon removed his bending was the same as Ozai's when Aang removed his bending: "What did you do to me?"
Zolt is the third known person to lose his bending in the Avatar universe, but the first to do so in The Legend of Korra, and the first known person to have his bending taken away by someone who is not an Avatar.
Zolt is also the first person besides Ozai who has shown the ability to be able to generate lighting at a fast speed. Mako later also displayed fast lightning generation.
Zolt possesses an accent similar to that of an Italian mobster.
Zolt's teachings of lighting generation and redirection to Mako were cut out of the show to save time.
