Baatar Jr.

Baatar Jr. is Suyin Beifong and Baatar's eldest son, nephew of Lin Beifong, and grandson of Toph Beifong. As Zaofu's engineer, he is responsible for enacting his father's designs. However, after Earth Queen Hou-Ting's murder and the subsequent decline of the Earth Kingdom's stability, he left Zaofu together with Kuvira to reunite the nation, much to the disapproval of his mother.

History
While Suyin hosted a dinner for Avatar Korra and her friends, Baatar Jr. and his father passed by the dining hall, where the latter informed the matriarch that they would have to eat in his office as they had a major breakthrough regarding the remodeling of a tram station. After the two left, Suyin proudly remarked that Baatar Jr. was an engineer who was responsible for handling all of his father's projects.

He later attended Opal's farewell dinner and subsequently accompanied the rest of the dining group to the rooftop, where they watched Opal depart for the Northern Air Temple.

After the Insurrection of the Red Lotus, Baatar Jr. left Zaofu in order to help Kuvira reunite the Earth Kingdom. This action greatly displeased his mother and he had a falling out with her, a conflict that still raged by 174 AG. At some point, he entered in a relationship with Kuvira, which progressed to the point that he proposed to her, which she accepted.

By 174 AG, he traveled the Earth Kingdom by train. When Bolin reported to him that two more states had agreed to join their alliance, he happily took the reports from him and relayed the message to Kuvira, stating that they had reached ninety percent of their goal. He was about to celebrate their achievement with Varrick, Zhu Li, and Bolin by drinking some tea, though when Kuvira stated that she refused to celebrate until the Earth Kingdom was reunited completely, he digressed and put his cup back down. However, the contents ended up being spilled on his clothing when their train suddenly halted due to an earthen obstruction on the tracks.

After Kuvira cleared their path, they continued on to the State of Yi, where Baatar Jr. found his sister Opal. He greeted her in a friendly matter, though when he asked how their mother was doing, Opal snapped at him, dismissing his question since she believed he did not care anyway. After the governor of Yi ordered Kuvira and her army to leave the state, Baatar Jr. retreated with everyone else to the border of the state, where they would wait a day for the governor to reconsider. When he did, they all returned and Baatar Jr. witness his fiancé claim the town in name of a united Earth Kingdom.
